NAME

       cronnext - time of next job cron will execute

SYNOPSIS

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

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 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

       -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 montly 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.
