What causes insserv: warning: script 'XXX.sh' missing LSB tags and overrides, and how is it prevented?

pi@raspberrypi /etc/init.d $ sudo rm 5_*

pi@raspberrypi /etc/init.d $ sudo vi /etc/init.d/5_second_cron

pi@raspberrypi /etc/init.d $ sudo chmod +x /etc/init.d/5_second_cron

pi@raspberrypi /etc/init.d $ sudo update-rc.d /etc/init.d/5_second_cron defaults^C

pi@raspberrypi /etc/init.d $

5_second_cron.sh is the following:

#!/bin/bash

while true

do

 /usr/bin/php /var/www/cron.php

 sleep 5

done

EDIT. Tried the following. Script just "hung" when I executed $ sudo update-rc.d /etc/init.d/5_second_cron.

pi@raspberrypi /etc/init.d $ sudo vi /etc/init.d/5_second_cron

pi@raspberrypi /etc/init.d $ sudo chmod +x /etc/init.d/5_second_cron

pi@raspberrypi /etc/init.d $ sudo update-rc.d /etc/init.d/5_second_cron defaults^.C

pi@raspberrypi /etc/init.d $

5_second_cron is the following:

#!/bin/bash

# /etc/init.d/5_second_cron



### BEGIN INIT INFO

while true

do

 /usr/bin/php /var/www/cron.php

 sleep 5

done

exit 0

EDIT2. Messing around some more, and now this:

pi@raspberrypi /etc/init.d $ sudo update-rc.d /etc/init.d/5_second_cron defaults

update-rc.d: using dependency based boot sequencing

update-rc.d: error: unable to read /etc/init.d//etc/init.d/5_second_cron

Sorry about the very late answer.

Init scripts aren't meant to run persistently. What I mean by this is that the init scripts are supposed to start the program, then exit, leaving the program running in the background. This way, the init system knows the runlevel has been reached.

Therefore, I would recommend putting your script into a separate folder, say /usr/bin.
This is what it would contain:

#!/bin/sh



while true

do

 /usr/bin/php /var/www/cron.php

 sleep 5

done

In your init script, put the following:

#!/bin/sh

### BEGIN INIT INFO

# Provides:          5_second_cron

# Required-Start:    $remote_fs $syslog

# Required-Stop:     $remote_fs $syslog

# Default-Start:     2 3 4 5

# Default-Stop:      0 1 6

# Short-Description: PHP Loop

# Description:       Initiate a given PHP file every 5 seconds

### END INIT INFO



case "$1" in

start)

    setsid /path/to/your/script.sh >/dev/null 2>&1 < /dev/null &

    ;;

*)

    ;;

esac

This makes it so the script takes the start argument, which is the way it is invoked, and also detaches the actual script from the process as a background daemon.

After these edits, simply run:

$ sudo insserv 5_second_cron
