.TH INIT-D-SCRIPT 5 "2014-02-09" "init-d-script" "File formats"
.SH NAME
init-d-script \- interpreter for short and simple init.d scripts.
.SH 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
.URL http://refspecs.linuxfoundation.org/LSB_4.1.0/LSB-Core-generic/LSB-Core-generic/iniscrptact.html "The LSB specification"
for information about init.d scripts in the LSB.
.P
This is a simple example on how init-d-script can be used to start and
stop a daemon with PID file support:
.P
.EX
#!/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
.EE
.P
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.
.P
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.
.P
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.
.P
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:
.P
.EX
alias do_reload=do_reload_sigusr1
