.SH DESCRIPTION
|
|
|
|
|
Determine the time cron will execute the next job. Without arguments, it
|
|
|
|
|
prints that time considering all crontabs, in number of seconds since the
|
|
|
|
|
Epoch, rounded to the minute. This number can be converted into other formats
|
|
|
|
|
using
|
|
|
|
|
.BR date (1),
|
|
|
|
|
like
|
|
|
|
|
.B date --date @43243254
|
|
|
|
|
|
|
|
|
|
The file arguments are optional. If provided,
|
|
|
|
|
.I cronnext
|
|
|
|
|
uses them as crontabs instead of the ones installed in the system.
