Hi,

The system usually will have a link in /etc/rcX.d to /etc/init.d/file these are the normal ways of starting something - they are normally started with the start/stop options. all you should have to do is decide what run level that you would like the program to start at and adjust the shell to sort iy out!

Dave

There are several ways to achieve this and you might want to research the "Unix boot process" to better understand the details involved.

gull04 had it right, an init-script is probably what you might need. Check the chkconfig --list command for a list of configured services and read its man page to understand how to modify the configuration of various init-scripts.

I hope this helps.

use crontab
edit crontab file (crontab -e) as below

Code:

@reboot <joblist>

joblist contains the jobs you have to run during start-up

write your commands in script file

Code:

script.sh
=======
cmds
....

edit crontab file by using command

Code:

crontab -e

the above command open crontab file
enter the following code in opened file

Code:

@reboot path/to/script.sh

save and quit

commands in script.sh will execute when system starts...

I'm stuck at the script potion. Not sure about the commands to use for the scripts. Any suggestion ? Thanks
