How to run a script at boot automatically using Linux

If you need to run a script at boot automatically using Linux, this is the easiest solution. this covers only System V behaviour and of course doesn't cover the various aspects of different runlevels nor the service kill at shutdown.

• Create a script file

# vi /etc/init.d/rc.local

...edit the script file calling your applications.

• Modify the executable flag

# chmod +x /etc/init.d/rc.local

• Activate the service at boot

# update-rc.d rc.local start 99 5 .

... this creates a symbolic link in /etc/rc5.d

• In case you want to remove the service

# update-rc.d -f rc.local remove
