CRONNEXT(1)                   User Commands                  CRONNEXT(1)

NAME         top

       cronnext - time of next job cron will execute

SYNOPSIS         top

       cronnext [-i users] [-e users] [-s] [-a] [-t time] [-q time] [-j
                command] [-l] [-c] [-f] [-h] [-V] [file]...

DESCRIPTION         top

       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.

OPTIONS         top

       -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.
