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.
