# This shell script will stop the mystic internet service (mis). It will fail out if the process #
|
||
|
|
# is not running and a stop attempt is made. It will also continually poll to make sure it stops #
|
||
|
|
# successfully, and if it is still running after 60 seconds, will be forcefully terminated. This #
|
||
|
|
# script can ideally be called as a fork within a systemd .service file. The script will exit #
|
||
|
|
# with an appropriate error code to indicate whether is was successful or not. It is intended to #
|
||
|
|
# work only with Debian, Ubuntu and other debian based distributions. #
