NAME
       uscheduled - a job scheduler

SYNOPSIS
       uscheduled [-d DIR]

DESCRIPTION
       uscheduled reads information about a number of jobs from DIR, or, if
       this is not given, from ~/.uschedule/.

       It then sleeps until one or more of the jobs have to be run, at which
       point it will try to run and either reschedule or delete them.

       uscheduled runs under the rights of the user for whom the programs are
       started. It changes to DIR on startup and runs in an own session. It
       doesn't detach from the terminal or move itself into the background.

       All time calculation is done in UTC.

JOB EXECUTION
       If uscheduled needs to start a job the following will be done:

       *  uscheduled forks a new process.

       *  the new process redirects /dev/null to file descriptors one and two,
          if desired.

       *  the new process changes to $HOME.

       *  the new process executes the program.

       *  uscheduled reschedules the job.  The users program will inherit the
          environment of the daemon, unless otherwise indicated during job
          creation time.  The standard input will be redirected from
          /dev/null. By default the file descriptors one and two (standard and
          error output) are not redirected, meaning that the output will go
          into the same log files as the output of the daemon, if any.

SIGNAL HANDLING
       uscheduled exits gracefully on SIGTERM. It reloads the job
       specifications on SIGHUP.
