By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations +below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it +becomes a de-facto standard. To achieve this, non-free programs must +be allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control +compilation and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at least + three years, to give the same user the materials specified in + Subsection 6a, above, for a charge no more than the cost of + performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply, and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices.

If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License +may add an explicit geographical distribution limitation excluding those +countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation.

For instance, we have a cluster of 4 Fedora servers which our end + users use as timeshare systems, using round robin DNS, and if one of + the servers is down it doesn't really matter too much. We don't even + backup the servers, relying on NFS home directories and rebuilding + from scratch using kickstart + cfengine if a server fails and can't + be restarted. However, the users have scattered crontab files around the 4 + servers, so that if the particular server a cron job is meant to run + on dies, the job doesn't run any more, and the crontab file may be + permanently lost. What we needed was a facility to allow crontabs in /var/spool/cron + on these 4 servers be NFS mounted from a single directory on our + NetApp filers (so giving us backups and snapshots), with any user + able to run "crontab -e" from any of the servers to manage a single + shared crontab, and for us in the IT Service to be able to set just + one of the 4 servers to run user crontab jobs at any time. However, + we needed to keep /etc/crontab and the files in /etc/cron.d/ + specific to each individual server still, and keep crond running on + all 4 servers.

Since the file is created with the user's euid, and + because utime is called on the file as root, an attacker can replace + the temporary file after it is created with a symlink to any file or + folder on disk, which will then have its atime and mtime set to 0. + This is certainly not a critical issue, but this action can be used + to deny service in many scenarios. For example, the cron daemon + checks the mtime of the crontab spool folder and its contents to + determine whether or not it needs to update its database of + cronjobs, and if these times are reset to 0, no new cronjobs will be + added. Other daemons relying on accurate timestamps may be similarly + affected. Finally, build tools such as make could be tricked into + not re-compiling source, based on an old timestamp.

It executes commands at +intervals specified in days. Unlike cron, it does not assume that the +system is running continuously. It can therefore be used to control +the execution of daily, weekly and monthly jobs (or anything with a +period of n days), on systems that don't run 24 hours a day. When +installed and configured properly, Anacron will make sure that the +commands are run at the specified intervals as closely as +machine-uptime permits. + + Every time Anacron is run, it reads a configuration file that +specifies the jobs Anacron controls, and their periods in days. If a +job wasn't executed in the last n days, where n is the period of that +job, Anacron executes it. Anacron then records the date in a special +timestamp file that it keeps for each job, so it can know when to run +it again. When all the executed commands terminate, Anacron exits. + + It is recommended to run Anacron from the system boot-scripts. +This way the jobs "whose time has come" will be run shortly after the +machine boots. A delay can be specified for each job so that the +machine isn't overloaded at boot time. + + In addition to running Anacron from the boot-scripts, it is also +recommended to schedule it as a daily cron-job (usually at an early +morning hour), so that if the machine is kept running for a night, +jobs for the next day will still be executed. + + + Why this may be useful ? + ------------------------ + + Most Unix-like systems have daily, weekly and monthly scripts that +take care of various "housekeeping chores" such as log-rotation, +updating the "locate" and "man" databases, etc. Daily scripts are +usually scheduled as cron-jobs to execute around 1-7 AM. Weekly +scripts are scheduled to run on Sundays. On machines that are turned +off for the night or for the weekend, these scripts rarely get run. + + Anacron solves this problem. These jobs can simply be scheduled as +Anacron-jobs with periods of 1, 7 and a special target called @monthly. + + + What Anacron is not ? + --------------------- + + Anacron is not an attempt to make cron redundant. It cannot +currently be used to schedule commands at intervals smaller than days. +It also does not guarantee that the commands will be executed at any +specific day or hour. + + It isn't a full-time daemon. It has to be executed from boot +scripts, from cron-jobs, or explicitly. + + + For more details, see the anacron(8) manpage. + + + Requirements + ------------ + + - A Linux system. (maybe other *NIX systems) + - A functioning syslog daemon. + - A functioning /usr/lib/sendmail command. (all MTAs should have + that). + + + Compilation and Installation + ---------------------------- + + - Untar the source package. + + - Check the Makefile. Edit as required. + + - Check the top of "global.h". You may want to change the syslog + facility and priorities, and the path to your MTA's sendmail + compatible command (/usr/lib/sendmail). + + - cd to the directory. + + - Type "make". + You can safely ignore warnings of the form: "*.d: No such file or + directory" + + - Become root. Type "make install". + + + Setup + ----- + +1. Locate your system's daily, weekly and monthly cron-jobs. + See your cron documentation for more details. + +2. Decide which of these jobs should be controlled by Anacron. + Remember that Anacron does not guarantee execution at any specific + day of the month, day of the week, or time of day.

Unlike +.BR cron(8) , +it does not assume that the machine is running continuously. Hence, it +can be used on machines that are not running 24 hours a day to control +regular jobs as daily, weekly, and monthly jobs. +.PP +Anacron reads a list of jobs from the +.I /etc/anacrontab +configuration file (see +.BR anacrontab (5)). +This file contains the list of jobs that Anacron controls. Each job +entry specifies a period in days, a delay in minutes, a unique job +identifier, and a shell command. +.PP +For each job, Anacron checks whether this job has been executed in the +last +.B n +days, where +.B n +is the time period specified for that job. If a job has not been +executed in +.B n +days or more, Anacron runs the job's shell command, after waiting for the +number of minutes specified as the delay parameter. +.PP +After the command exits, Anacron records the date (excludes the hour) in +a special timestamp file for that job, so it knows when to execute that +job again. +.PP +When there are no more jobs to be run, Anacron exits. +.PP +Anacron only considers jobs whose identifier, as specified in +.BR anacrontab (5), +matches any of the +.I job +command-line arguments. The +.I job +command-line arguments can be represented by shell wildcard patterns (be +sure to protect them from your shell with adequate quoting). Specifying +no +.I job +command-line arguments is equivalent to specifying "*" (that is, all +jobs are considered by Anacron). +.PP +Unless Anacron is run with the +.B \-d +option (specified below), it forks to the background when it starts, and +any parent processes exit immediately. +.PP +Unless Anacron is run with the +.B \-s +or +.B \-n +options, it starts jobs immediately when their delay is over. The +execution of different jobs is completely independent. +.PP +If an executed job generates any output to standard output or to standard +error, the output is mailed to the user under whom Anacron is running +(usually root), or to the address specified in the +.B MAILTO +environment variable in the +.I /etc/anacrontab +file, if such exists. If the +.B LOGNAME +environment variable is set, it is used in the From: field of the mail. +.PP +Any informative messages generated by Anacron are sent to +.BR syslogd (8) +or +.BR rsyslogd (8) +under with facility set to +.B cron +and priority set to +.BR notice . +Any error messages are sent with the priority +.BR error . +.PP +"Active" jobs (i.e., jobs that Anacron already decided to run and are now +waiting for their delay to pass, and jobs that are currently being +executed by Anacron), are "locked", so that other copies of Anacron +cannot run them at the same time. +.SH OPTIONS +.TP +.B \-f +Forces execution of all jobs, ignoring any timestamps. +.TP +.B \-u +Updates the timestamps of all jobs to the current date, but does not run +any. +.TP +.B \-s +Serializes execution of jobs. Anacron does not start a new job before the +previous one finished. +.TP +.B \-n +Runs jobs immediately and ignores the specified delays in the +.I /etc/anacrontab +file. This options implies +.BR -s . +.TP +.B \-d +Does not fork Anacron to the background. In this mode, Anacron will +output informational messages to standard error, as well as to syslog. +The output of any job is mailed by Anacron. +.TP +.B \-q +Suppresses any messages to standard error. Only applicable with +.BR -d . +.TP +.B -t some_anacrontab +Uses the specified anacrontab, rather than the +.I /etc/anacrontab +default one. +.TP +.B -T +Anacrontab testing. Tests the +.I /etc/anacrontab +configuration file for validity. If there is an error in the file, it is +shown on the standard output and Anacron returns the value of 1. Valid +anacrontabs return the value of 0. +.TP +.B -S spooldir +Uses the specified spooldir to store timestamps in. This option is +required for users who wish to run anacron themselves. +.TP +.B -V +Prints version information, and exits. +.TP +.B -h +Prints short usage message, and exits. +.SH SIGNALS +After receiving a +.B SIGUSR1 +signal, Anacron waits for any running jobs to finish and then exits. +This can be used to stop Anacron cleanly. +.SH NOTES +Make sure your time-zone is set correctly before Anacron is started since +the time-zone affects the date. This is usually accomplished by setting +the TZ environment variable, or by installing a +.I /usr/lib/zoneinfo/localtime +file. See +.BR tzset (3) +for more information. +.PP +Timestamp files are created in the spool directory for each job specified +in an anacrontab. These files are never removed automatically by +Anacron, and should be removed by hand if a job is no longer being +scheduled. +.SH FILES +.TP +.I /etc/anacrontab +Contains specifications of jobs.

In case systemd is enabled, then unit file is installed into +.I /lib/systemd/system/crond.service +and daemon is started by +.I systemctl start crond.service +command. It returns immediately, thus, there is no need to need to start it with +the '&' parameter. +.PP +.I Cron +searches +.I /var/spool/cron +for crontab files which are named after accounts in +.I /etc/passwd; +The found crontabs are loaded into the memory. +.I Cron +also searches for +.I /etc/anacrontab +and any files in the +.I /etc/cron.d +directory, which have a different format (see +.BR crontab (5)). +.I Cron +examines all stored crontabs and checks each job to see if it needs to be +run in the current minute. When executing commands, any output is mailed +to the owner of the crontab (or to the user specified in the +.I MAILTO +environment variable in the crontab, if such exists). Any job output can +also be sent to syslog by using the +.B "\-s" +option. +.PP +There are two ways how changes in crontables are checked. The first +method is checking the modtime of a file. The second method is using the +inotify support. Using of inotify is logged in the +.I /var/log/cron +log after the daemon is started. The inotify support checks for changes +in all crontables and accesses the hard disk only when a change is +detected. +.PP +When using the modtime option, +.I Cron +checks its crontables' modtimes every minute to check for any changes and +reloads the crontables which have changed. There is no need to restart +.I Cron +after some of the crontables were modified. The modtime option is also +used when inotify can not be initialized. +.PP +.I Cron +checks these files and directories: +.TP +.IR /etc/crontab +system crontab. Nowadays the file is empty by default. Originally it +was usually used to run daily, weekly, monthly jobs. By default these +jobs are now run through anacron which reads +.IR /etc/anacrontab +configuration file. See +.BR anacrontab (5) +for more details. +.TP +.IR /etc/cron.d/ +directory that contains system cronjobs stored for different users. +.TP +.IR /var/spool/cron +directory that contains user crontables created by the +.IR crontab +command. +.PP +Note that the +.BR crontab (1) +command updates the modtime of the spool directory whenever it changes a +crontab. +.PP +.SS Daylight Saving Time and other time changes +Local time changes of less than three hours, such as those caused by the +Daylight Saving Time changes, are handled in a special way. This only +applies to jobs that run at a specific time and jobs that run with a +granularity greater than one hour. Jobs that run more frequently are +scheduled normally. +.PP +If time was adjusted one hour forward, those jobs that would have run in +the interval that has been skipped will be run immediately. Conversely, +if time was adjusted backward, running the same job twice is avoided. +.PP +Time changes of more than 3 hours are considered to be corrections to the +clock or the timezone, and the new time is used immediately. +.PP +It is possible to use different time zones for crontables. See +.BR crontab (5) +for more information. +.SS PAM Access Control +.IR Cron +supports access control with PAM if the system has PAM installed. For +more information, see +.BR pam (8). +A PAM configuration file for +.IR crond +is installed in +.IR /etc/pam.d/crond . +The daemon loads the PAM environment from the pam_env module. This can +be overridden by defining specific settings in the appropriate crontab +file. +.SH "OPTIONS" +.TP +.B "\-h" +Prints a help message and exits. +.TP +.B "\-i" +Disables inotify support. +.TP +.B "\-m" +This option allows you to specify a shell command to use for sending +.I Cron +mail output instead of using +.BR sendmail (8) +This command must accept a fully formatted mail message (with headers) on +standard input and send it as a mail message to the recipients specified +in the mail headers. Specifying the string +.I "off" +(i.e., crond -m off) +will disable the sending of mail. +.TP +.B "\-n" +Tells the daemon to run in the foreground. This can be useful when +starting it out of init. With this option is needed to change pam setting. +.I /etc/pam.d/crond +must not enable +.I pam_loginuid.so +module. +.TP +.B "\-f" +the same as -n, consistent with other crond implementations. +.TP +.B "\-p" +Allows +.I Cron +to accept any user set crontables. +.TP +.B "\-P" +Don't set PATH. PATH is instead inherited from the environment. +.TP +.B "\-c" +This option enables clustering support, as described below. +.TP +.B "\-s" +This option will direct +.I Cron +to send the job output to the system log using +.BR syslog (3). +This is useful if your system does not have +.BR sendmail (8) +installed or if mail is disabled. +.TP +.B "\-x" +This option allows you to set debug flags. +.TP +.B "\-V" +Print version and exit. +.SH SIGNALS +When the +.I SIGHUP +is received, the +.I Cron +daemon will close and reopen its log file. This proves to be useful in +scripts which rotate and age log files. Naturally, this is not relevant +if +.I Cron +was built to use +.IR syslog (3). +.SH CLUSTERING SUPPORT +In this version of +.IR Cron +it is possible to use a network-mounted shared +.I /var/spool/cron +across a cluster of hosts and specify that only one of the hosts should +run the crontab jobs in this directory at any one time. This is done by +starting +.I Cron +with the +.B \-c +option, and have the +.I /var/spool/cron/.cron.hostname +file contain just one line, which represents the hostname of whichever +host in the cluster should run the jobs. If this file does not exist, or +the hostname in it does not match that returned by +.BR gethostname (2), +then all crontab files in this directory are ignored. This has no effect +on cron jobs specified in the +.I /etc/crontab +file or on files in the +.I /etc/cron.d +directory. These files are always run and considered host-specific. +.PP +Rather than editing +.I /var/spool/cron/.cron.hostname +directly, use the +.B \-n +option of +.BR crontab (1) +to specify the host. +.PP +You should ensure that all hosts in a cluster, and the file server from +which they mount the shared crontab directory, have closely synchronised +clocks, e.g., using +.BR ntpd (8), +otherwise the results will be very unpredictable. +.PP +Using cluster sharing automatically disables inotify support, because +inotify cannot be relied on with network-mounted shared file systems. +.SH CAVEATS +All +.BR crontab +files have to be regular files or symlinks to regular files, they must +not be executable or writable for anyone else but the owner. This +requirement can be overridden by using the +.B \-p +option on the crond command line. If inotify support is in use, changes +in the symlinked crontabs are not automatically noticed by the cron +daemon. The cron daemon must receive a SIGHUP signal to reload the +crontabs. This is a limitation of the inotify API. +.PP +The syslog output will be used instead of mail, when sendmail is not +installed. +.SH "SEE ALSO" +.BR crontab (1), +.BR crontab (5), +.BR inotify (7), +.BR pam (8) +.SH AUTHOR +.MT vixie@isc.org +Paul Vixie +.ME +.br +.MT mmaslano@redhat.com +Marcela Mašláňová +.ME +.br +.MT colin@colin-dean.org +Colin Dean +.ME +.br +.MT tmraz@fedoraproject.org +Tomáš Mráz +.ME diff --git a/man/crond.8 b/man/crond.8 new file mode 100644 index 0000000..64c7c26 --- /dev/null +++ b/man/crond.8 @@ -0,0 +1 @@ +.so man8/cron.8 diff --git a/man/cronnext.1 b/man/cronnext.1 new file mode 100644 index 0000000..5dab9fb --- /dev/null +++ b/man/cronnext.1 @@ -0,0 +1,86 @@ +.TH CRONNEXT 1 "2017-06-11" "cronie" "User Commands" +.SH NAME +cronnext \- time of next job cron will execute +.SH SYNOPSIS +.TP 9 +.B cronnext +[\fB-i \fIusers\fR] [\fB-e \fIusers\fR] [\fB-s\fR] +[\fB-a\fR] +[\fB-t \fItime\fR] [\fB-q \fItime\fR] [\fB-j \fIcommand\fR] +[\fB-l\fR] [\fB-c\fR] [\fB-f\fR] [\fB-h\fR] [\fB-V\fR] +[file]... +.SH DESCRIPTION +Determine the time cron will execute the next job.

Each user can have their own crontab, and though these are files +in +.IR /var/spool/ , +they are not intended to be edited directly. For SELinux in MLS mode, +you can define more crontabs for each range. For more information, see +.BR selinux (8). +.PP +In this version of +.IR Cron +it is possible to use a network-mounted shared +.I /var/spool/cron +across a cluster of hosts and specify that only one of the hosts should +run the crontab jobs in the particular directory at any one time. You +may also use +.BR crontab +from any of these hosts to edit the same shared set of crontab files, and +to set and query which host should run the crontab jobs. +.PP +Scheduling cron jobs with +.BR crontab +can be allowed or disallowed for different users. For this purpose, use the +.I cron.allow +and +.I cron.deny +files. If the +.I cron.allow +file exists, a user must be listed in it to be allowed to use +.BR crontab . +If the +.I cron.allow +file does not exist but the +.I cron.deny +file does exist, then a user must +.I not +be listed in the +.I cron.deny +file in order to use +.BR crontab. +If neither of these files exist, then only the super user is allowed to use +.BR crontab . +.PP +Another way to restrict the scheduling of cron jobs beyond +.BR crontab +is to use PAM authentication in +.I /etc/security/access.conf +to set up users, which are allowed or disallowed to use +.BR crontab +or modify system cron jobs in the +.IR /etc/cron.d/ +directory. +.PP +The temporary directory can be set in an environment variable. If it is +not set by the user, the +.I /tmp +directory is used. +.PP +When listing a crontab on a terminal the output will be colorized unless +an environment variable +.I NO_COLOR +is set. +.PP +On edition or deletion of the crontab, a backup of the last crontab will be saved to +.I $XDG_CACHE_HOME/crontab/crontab.bak +or +.I $XDG_CACHE_HOME/crontab/crontab..bak +if +.B -u +is used. +If the +.I XDG_CACHE_HOME +environment variable is not set, +.I $HOME/.cache +will be used instead. +.PP +.SH "OPTIONS" +.TP +.B "\-u" +Specifies the name of the user whose crontab is to be modified.

If a hostname is supplied, the host whose hostname returned +by +.BR gethostname (2) +matches the supplied hostname, will be selected to run the selected cron jobs subsequently. If there +is no host in the cluster matching the supplied hostname, or you explicitly specify +an empty hostname, then the selected jobs will not be run at all.

Each user can define their own crontab. Commands defined +in any given crontab are executed under the user who owns that particular +crontab. Uucp and News usually have their own crontabs, eliminating the +need for explicitly running +.BR su (1) +as part of a cron command. +.PP +Blank lines, leading spaces, and tabs are ignored. Lines whose first +non-white space character is a pound-sign (#) are comments, and are not +processed. Note that comments are not allowed on the same line as cron +commands, since they are considered a part of the command. Similarly, +comments are not allowed on the same line as environment variable +settings. +.PP +An active line in a crontab is either an environment setting or a cron +command. An environment setting is of the form: +.PP + name = value +.PP +where the white spaces around the equal-sign (=) are optional, and any +subsequent non-leading white spaces in +.I value +is a part of the value assigned to +.IR name . +The +.I value +string may be placed in quotes (single or double, but matching) to +preserve leading or trailing white spaces. +.PP +Several environment variables are set up automatically by the +.BR cron (8) +daemon. +.I SHELL +is set to /bin/sh, and +.I LOGNAME +and +.I HOME +are set from the /etc/passwd line of the crontab\'s owner. +.I HOME +and +.I SHELL +can be overridden by settings in the crontab; LOGNAME can not. +.PP +(Note: the +.I LOGNAME +variable is sometimes called +.I USER +on BSD systems and is also automatically set). +.PP +In addition to +.IR LOGNAME , +.IR HOME , +and +.IR SHELL , +.BR cron (8) +looks at the +.I MAILTO +variable if a mail needs to be send as a result of running any commands +in that particular crontab. If +.I MAILTO +is defined (and non-empty), mail is sent to the specified address. If +.I MAILTO +is defined but empty +.RI ( MAILTO="" ), +no mail is sent. Otherwise, mail is sent to the owner of the crontab. +This option is useful if you decide to use /bin/mail instead of +/usr/lib/sendmail as your mailer. Note that /bin/mail does not provide +aliasing and UUCP usually does not read its mail. If +.I MAILFROM +is defined (and non-empty), it is used as the envelope sender address, +otherwise, the username of the executing user is used. This variable is +also inherited from the crond process environment. +.PP +(Note: Both +.I MAILFROM +and +.I MAILTO +variables are expanded, so setting them as in the following example works as expected: MAILFROM=cron-$USER@cron.com ($USER is replaced by the system user) ) +.PP +By default, cron sends a mail using the 'Content-Type:' header +of 'text/plain' with the 'charset=' parameter set to the 'charmap/codeset' +of the locale in which +.BR crond (8) +is started up, i.e., either the default system locale, if no LC_* +environment variables are set, or the locale specified by the LC_* +environment variables (see +.BR locale (7)). +Different character encodings can be used for mailing cron job outputs by +setting the +.I CONTENT_TYPE +and +.I CONTENT_TRANSFER_ENCODING +variables in a crontab to the correct values of the mail headers of those +names. +.PP +The +.I CRON_TZ +variable specifies the time zone specific for the cron table. The user +should enter a time according to the specified time zone into the table. +The time used for writing into a log file is taken from the local time +zone, where the daemon is running. +.PP +The +.I MLS_LEVEL +environment variable provides support for multiple per-job SELinux +security contexts in the same crontab. By default, cron jobs execute +with the default SELinux security context of the user that created the +crontab file. When using multiple security levels and roles, this may +not be sufficient, because the same user may be running in different +roles or in different security levels. For more information about roles +and SELinux MLS/MCS, see +.BR selinux (8) +and the crontab example mentioned later on in this text. You can set the +.I MLS_LEVEL +variable to the SELinux security context string specifying the particular +SELinux security context in which you want jobs to be run. +.B crond +will then set the execution context of those jobs that meet the +specifications of the particular security context. For more information, +see +.BR crontab (1)\ -s\ option. +.PP +The +.I RANDOM_DELAY +variable allows delaying job startups by random amount of minutes with +upper limit specified by the variable. The random scaling factor is +determined during the cron daemon startup so it remains constant for +the whole run time of the daemon. +.PP +The format of a cron command is similar to the V7 standard, with a number +of upward-compatible extensions. Each line has five time-and-date fields +followed by a +.BR user name +(if this is the +.BR system +crontab file), and followed by a command. Commands are executed by +.BR cron (8) +when the 'minute', 'hour', and 'month of the year' fields match the +current time, +.I and +at least one of the two 'day' fields ('day of month', or 'day of week') +match the current time (see "Note" below). +.PP +Note that this means that non-existent times, such as the "missing hours" +during the daylight savings time conversion, will never match, causing +jobs scheduled during the "missing times" not to be run. Similarly, +times that occur more than once (again, during the daylight savings time +conversion) will cause matching jobs to be run twice. +.PP +.BR cron (8) +examines cron entries every minute. +.PP +The time and date fields are: +.IP +.ta 1.5i +field allowed values +.br +----- -------------- +.br +minute 0-59 +.br +hour 0-23 +.br +day of month 1-31 +.br +month 1-12 (or names, see below) +.br +day of week 0-7 (0 or 7 is Sunday, or use names) +.br +.PP +A field may contain an asterisk (*), which always stands for +"first\-last". +.PP +Ranges of numbers are allowed. Ranges are two numbers separated with a +hyphen. The specified range is inclusive. For example, 8-11 for +an 'hours' entry specifies execution at hours 8, 9, 10, and 11. The first +number must be less than or equal to the second one. +.PP +Randomization of the execution time within a range can be used. +A random number within a range specified as two numbers separated with +a tilde is picked. The specified range is inclusive. +For example, 6~15 for a 'minutes' entry picks a random minute +within 6 to 15 range. The random number is picked when crontab file is parsed. +The first number must be less than or equal to the second one. You might omit +one or both of the numbers specifying the range. For example, ~ for a 'minutes' +entry picks a random minute within 0 to 59 range. +.PP +Lists are allowed. A list is a set of numbers (or ranges) separated by +commas. Examples: "1,2,5,9", "0-4,8-12". +.PP +Step values can be used in conjunction with ranges. Following a range +with "/" specifies skips of the number's value through the range. +For example, "0-23/2" can be used in the 'hours' field to specify command +execution for every other hour (the alternative in the V7 standard is +"0,\:2,\:4,\:6,\:8,\:10,\:12,\:14,\:16,\:18,\:20,\:22"). Step values are +also permitted after an asterisk, so if specifying a job to be run every +two hours, you can use "*/2". Please note that steps are evaluated just +within the field they are applied to. For example "*/23" in hours field +means to execute the job on the hour 0 and the hour 23 within a calendar +day. See "NOTES" below for a workaround. +.PP +Names can also be used for the 'month' and 'day of week' fields. Use the +first three letters of the particular day or month (case does not +matter). Ranges and lists of names are allowed. Examples: "mon,wed,fri", +"jan-mar". +.PP +If the UID of the owner is 0 (root), the first character of a crontab +entry can be "-" character. This will prevent cron from writing a syslog +message about the command being executed. +.PP +The "sixth" field (the rest of the line) specifies the command to be run. +The entire command portion of the line, up to a newline or a "%" +character, will be executed by /bin/sh or by the shell specified in the +SHELL variable of the cronfile. A "%" character in the command, unless +escaped with a backslash (\\), will be changed into newline characters, +and all data after the first % will be sent to the command as standard +input. +.PP +Note: The day of a command's execution can be specified in the following +two fields \(em 'day of month', and 'day of week'. If both fields are +restricted (i.e., do not contain the "*" character), the command will be +run when +.I either +field matches the current time. For example, +.br +"30 4 1,15 * 5" would cause a command to be run at 4:30 am on the 1st and +15th of each month, plus every Friday. +.PP +A crontab file syntax can be tested before an install using the -T option. See +.BR crontab (1) +for details. +.SH EXAMPLE CRON FILE +.nf +# use /bin/sh to run commands, no matter what /etc/passwd says +SHELL=/bin/sh +# mail any output to `paul', no matter whose crontab this is +MAILTO=paul +# +CRON_TZ=Japan +# run five minutes after midnight, every day +5 0 * * * $HOME/bin/daily.job >> $HOME/tmp/out 2>&1 +# run at 2:15pm on the first of every month -- output mailed to paul +15 14 1 * * $HOME/bin/monthly +# run at 10 pm on weekdays, annoy Joe +0 22 * * 1-5 mail -s "It's 10pm" joe%Joe,%%Where are your kids?% +23 0-23/2 * * * echo "run 23 minutes after midn, 2am, 4am ..., everyday" +5 4 * * sun echo "run at 5 after 4 every sunday" +.fi +.SH Jobs in /etc/cron.d/ +The jobs in +.I cron.d +and +.I /etc/crontab +are system jobs, which are used usually for more than one user, thus, +additionally the username is needed.

For example, specifying "0/35" for the minute field of a +crontab entry won\'t cause that entry to be executed every 35 minutes; +instead, it will be executed twice every hour, at 0 and 35 minutes past. +For more fine-grained control you can do something like this: +.nf +* * * * * if [ $(expr \\( $(date +%s) / 60 \\) % 58) = 0 ]; then echo this runs every 58 minutes; fi +0 * * * * if [ $(expr \\( $(date +%s) / 3600 \\) % 23) = 0 ]; then echo this runs every 23 hours on the hour; fi +.fi +Adjust as needed if your +.BR date (1) +command does not accept "+%s" as the format string specifier to output +the current UNIX timestamp. +.SH SELinux with multi level security (MLS) +In a crontab, it is important to specify a security level by +.I crontab \-s +or specifying the required level on the first line of the crontab. Each +level is specified in +.IR /etc/selinux/targeted/seusers . +When using crontab in the MLS mode, it is especially important to: +.br +- check/change the actual role, +.br +- set correct +.I role for +.IR directory , +which is used for input/output. +.SH EXAMPLE FOR SELINUX MLS +.nf +# login as root +newrole -r sysadm_r +mkdir /tmp/SystemHigh +chcon -l SystemHigh /tmp/SystemHigh +crontab -e +# write in crontab file +MLS_LEVEL=SystemHigh +0-59 * * * * id -Z > /tmp/SystemHigh/crontest +.fi +.SH FILES +.I /etc/crontab +main system crontab file. +.I /var/spool/cron/ +a directory for storing crontabs defined by users. +.I /etc/cron.d/ +a directory for storing system crontabs. +.SH "SEE ALSO" +.BR cron (8), +.BR crontab (1) +.SH EXTENSIONS +These special time specification "nicknames" which replace the 5 initial +time and date fields, and are prefixed with the '@' character, are +supported: +.PP +.nf +@reboot : Run once after reboot. +@yearly : Run once a year, ie.

"0 0 * * *". +@hourly : Run once an hour, ie. "0 * * * *". +.fi +.SH CAVEATS +.BR crontab +files have to be regular files or symlinks to regular files, they must +not be executable or writable for anyone else but the owner. This +requirement can be overridden by using the +.B \-p +option on the crond command line. If inotify support is in use, changes +in the symlinked crontabs are not automatically noticed by the cron +daemon. The cron daemon must receive a SIGHUP signal to reload the +crontabs. This is a limitation of the inotify API. +.PP +cron requires that each entry in a crontab end in a newline character. If the +last entry in a crontab is missing a newline (i.e.\& terminated by EOF), +cron will consider the crontab (at least partially) broken. +A warning will be written to syslog. +.SH AUTHOR +.MT vixie@isc.org +Paul Vixie +.ME diff --git a/missing b/missing new file mode 100755 index 0000000..625aeb1 --- /dev/null +++ b/missing @@ -0,0 +1,215 @@ +#! /bin/sh +# Common wrapper for a few potentially missing GNU programs. + +scriptversion=2018-03-07.03; # UTC + +# Copyright (C) 1996-2018 Free Software Foundation, Inc. +# Originally written by Fran,cois Pinard , 1996. + +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2, or (at your option) +# any later version. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The idea + is that you would use these pre-tested macros to solve a + very specific set of problems, and they would run fast. + Caution: no side-effects in arguments please!! They may be + evaluated MANY times!! + + These macros operate a stack of objects. Each object starts life + small, and may grow to maturity. (Consider building a word syllable + by syllable.) An object can move while it is growing. Once it has + been "finished" it never changes address again. So the "top of the + stack" is typically an immature growing object, while the rest of the + stack is of mature, fixed size and fixed address objects. + + These routines grab large chunks of memory, using a function you + supply, called 'obstack_chunk_alloc'. On occasion, they free chunks, + by calling 'obstack_chunk_free'. You must define them and declare + them before using any obstack macros. + + Each independent stack is represented by a 'struct obstack'. + Each of the obstack macros expects a pointer to such a structure + as the first argument. + + One motivation for this package is the problem of growing char strings + in symbol tables. Unless you are "fascist pig with a read-only mind" + --Gosper's immortal quote from HAKMEM item 154, out of context--you + would not like to put any arbitrary upper limit on the length of your + symbols. + + In practice this often means you will build many short symbols and a + few long symbols. At the time you are reading a symbol you don't know + how long it is. One traditional method is to read a symbol into a + buffer, realloc()ating the buffer every time you try to read a symbol + that is longer than the buffer. This is beaut, but you still will + want to copy the symbol from the buffer to a more permanent + symbol-table entry say about half the time. + + With obstacks, you can work differently. Use one obstack for all symbol + names. As you read a symbol, grow the name in the obstack gradually. + When the name is complete, finalize it. Then, if the symbol exists already, + free the newly read name. + + The way we do this is to take a large chunk, allocating memory from + low addresses. When you want to build a symbol in the chunk you just + add chars above the current "high water mark" in the chunk. When you + have finished adding chars, because you got to the end of the symbol, + you know how long the chars are, and you can create a new object. + Mostly the chars will not burst over the highest address of the chunk, + because you would typically expect a chunk to be (say) 100 times as + long as an average object. + + In case that isn't clear, when we have enough chars to make up + the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed) + so we just point to it where it lies. No moving of chars is + needed and this is the second win: potentially long strings need + never be explicitly shuffled. Once an object is formed, it does not + change its address during its lifetime. + + When the chars burst over a chunk boundary, we allocate a larger + chunk, and then copy the partly formed object from the end of the old + chunk to the beginning of the new larger chunk. We then carry on + accreting characters to the end of the object as we normally would. + + A special macro is provided to add a single char at a time to a + growing object. This allows the use of register variables, which + break the ordinary 'growth' macro. + + Summary: + We allocate large chunks. + We carve out one object at a time from the current chunk. + Once carved, an object never moves. + We are free to append data of any size to the currently + growing object. + Exactly one object is growing in an obstack at any one time. + You can run one obstack per control block. + You may have as many control blocks as you dare. + Because of the way we do it, you can "unwind" an obstack + back to a previous state.
