CRONNEXT(1) User Commands CRONNEXT(1)
cronnext - time of next job cron will execute
cronnext [-i users] [-e users] [-s] [-a] [-t time] [-q time] [-j
command] [-l] [-c] [-f] [-h] [-V] [file]...
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 date(1), like date --date
@43243254
The file arguments are optional. If provided, cronnext uses them
as crontabs instead of the ones installed in the system.
-i user,user,user,...
Consider only the crontabs of the specified users. Use
*system* for the system crontab.
-e user,user,user,...
Do not consider the crontabs of the specified users.
-s Do not consider the system crontab, usually the
/etc/crontab file. The system crontab usually contains the
hourly, daily, weekly and monthly crontabs, which might be
better dealt with anacron(8).
-a Use the crontabs installed in the system in addition to the
ones passed as file arguments. This is implicit if no file
is passed.
-t time
Determine the next job from this time, instead of now. The
time is expressed in number of seconds since the Epoch, as
obtained for example by date +%s --date "now + 2 hours",
and is internally rounded to the minute.
-q time
Do not check jobs over this time, expressed in the same way
as in option -t.
-j command
Only look for jobs that contain command as a substring.
-l Print the whole entries of the jobs that are the next to be
executed by cron. The default is to only print their next
time of execution.
-c Print every entry in every crontab with the next time it is
executed.
-f Print all jobs that are executed in the given interval.
Requires option -q.
-h Print usage output and exit.
-V Print version and exit.
