Как я могу легко создать скрипт /etc/init.d/?

Debian и его производные имеют файл skeleton, расположенный в каталоге /etc/init.d, который должен делать именно это, то есть помогать пользователям писать адекватные сценарии. Я использовал его несколько раз, мне кажется, это именно то, что вы ищете.

I have found this gist: https://gist.github.com/naholyr/4275302

This is basically what was I was searching for.

Here is my (modified) version of the script:

#!/bin/bash SERVICE_FILE=$(tempfile) cat >> $SERVICE_FILE <<\EOF #!/bin/sh ### BEGIN INIT INFO # Provides: <NAME> # Required-Start: $local_fs $network $named $time $syslog # Required-Stop: $local_fs $network $named $time $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Description: <DESCRIPTION> ### END INIT INFO SCRIPT=<COMMAND> RUNAS=<USERNAME> PIDFILE=/var/run/<NAME>.pid LOGFILE=/var/log/<NAME>.log start() { if [ -f "$PIDFILE" ] && kill -0 $(cat "$PIDFILE"); then echo 'Service already running' >&2 return 1 fi echo 'Starting service…' >&2 local CMD="$SCRIPT &> \"$LOGFILE\" & echo \$!" su -c "$CMD" $RUNAS > "$PIDFILE" echo 'Service started' >&2 } stop() { if [ ! -f "$PIDFILE" ] || ! kill -0 $(cat "$PIDFILE"); then echo 'Service not running' >&2 return 1 fi echo 'Stopping service…' >&2 kill -15 $(cat "$PIDFILE") && rm -f "$PIDFILE" echo 'Service stopped' >&2 } uninstall() { echo -n "Are you really sure you want to uninstall this service?
