Shell Programming and Scripting

Hi

I had written a piece of script .

Please let me know is it possible to run / execute this script at system startup ??

Thanks in advance .

Quite possible. It depends on your distro, but most of them have /etc/local.start, /etc/conf.d/local.start, or some equivalent. Adding a line for your script file to it will cause it to run when the system finishes booting to its login prompts.

It's also possible to specify a script to run on start via a user's crontab:

Code:

@startup /path/to/my/script.sh

Thank you very much .

Hi ,

I am uisng Enterprise Linux 5 , i could not find anything as what you mentioned .

Can anybody please help me in this case .

I usually create a script in /etc/rc3.d called S99local for this type of thing. That way when the system hits runlevel 3, it runs my script after everything else has started. Just make sure the permissions are set up correctly and owned by the superuser account.

Good luck!

What version of Linux/Unix are you using? Typically every version of *nix has some sort of launch daemon that controls and launches everything at start up. For example, the Debian/Ubuntu flavors of Linux use /etc/init.d which can be used to launch your script at start up regardless if any user is logged in or not system wide.

If you want it to trigger when a particular user logs in you will have to set some kind of log in hook, and that can also be done by a launch daemon or it can be done by editing the user's default shell to launch the script when ran by editing their profile.

can you give some more details on what you are trying to accomplish here?
