NAME

       init-d-script - interpreter for short and simple init.d scripts.

DESCRIPTION

       Generic  init.d  script framework to reduce the redundant code in /etc/init.d/.  The goal is to create an
       init.d script that is Debian and LSB compliant.  When the Debian policy conflict with the LSB, the Debian
       policy  take  preference.   See The LSB specification ⟨http://refspecs.linuxfoundation.org/LSB_4.1.0/LSB-
       Core-generic/LSB-Core-generic/iniscrptact.html⟩ for information about init.d scripts in the LSB.

       This is a simple example on how init-d-script can be used to start  and  stop  a  daemon  with  PID  file
       support:

       #!/lib/init/init-d-script
       ### BEGIN INIT INFO
       # Provides:          atd
       # Required-Start:    $syslog $time $remote_fs
       # Required-Stop:     $syslog $time $remote_fs
       # Default-Start:     2 3 4 5
       # Default-Stop:      0 1 6
       # Short-Description: run at jobs
       # Description:       Debian init script to start the daemon
       #                    running at jobs.
       ### END INIT INFO
       DAEMON=/usr/sbin/atd

       In  addition  to  the  DAEMON  setting,  one can specify DESC, NAME, PIDFILE (none means no PID file), or
       implement   override   functions   do_force_reload_override,   do_reload_override,   do_restart_override,
       do_start_override,    do_start_cmd_override,   do_start_prepare,   do_start_cleanup   do_status_override,
       do_stop_override, do_stop_prepare, do_stop_cleanup and do_stop_cmd_override.

       If the daemon support reloading, implement the do_reload function to make the init.d script recognize the
       reload operation as well as use it for the force-reload operation.

       If  DAEMON  is 'none', the check to see if the daemon is installed is disabled, and replacement functions
       do_start_cmd_override, do_stop_cmd_override and do_status_override functions must be implemented.

       Services supporting reload should define the do_reload function.  If the service handle  reload  using  a
       SIGUSR1 signal, the following alias can be used instead of implementing ones own do_reload function:

       alias do_reload=do_reload_sigusr1
