Probably, the easiest option is to add the script to the rc.local file.

Hello Haris,
yes you can put this scrip in rc.local which will execute after all other system init scripts.

if you are not really sure go through below sample script you can modify acordingly, thanks,

Hi Khan,
You got the right answer from all above. "/etc/rc.local" is the final place that kernel look for any startup scripts during the boot process.
you can put your commands on this file

writing all the commands you want to execute at the boot time as a shell script and put that shell script path on rc.local file is what i do and recommend.

Good Luck..!

Hi Khan,
rc.local file is already there and all you need to add your commands to that file or add the paths to shell scripts on that files.

by the way please show some appreciation for all that gave you answers with points.

Good Luck..!

Hi,
The easiest way to add startup things open /etc/rc.d/rc.local and add what you want to this is the startup file for user.

[root@rspc521 rc.d]# ll rc.local
-rwxr-xr-x 1 root root 220 Jun 24 2003 rc.local

As the others said, the easiest way is to add it to rc.local.

But! if you need it to execute on a specific position in the startup sequence then you need probably need to study the method used to start and shutdown services for that particular distribution.

If you just need it to start without any other dependencies or anything then rc.local version is just fine and probably the most simple one.
