Running a startup script in UBUNTU 9.04

Last few days I was trying out some new script in which we had to log in and start the script.. Well while I messed up the whole thing as I had put the script before logging in and I could not use my computer furthermore( ofcourse, I removed the script but that is something different) so I decided to put how to put a script before logging in and after logging in Ubuntu

PUT A SCRIPT BEFORE LOGGING IN

1. Write your script in bash
2. Save it in a file named startup or anything you wish to..
3. Copy this file to the directory /etc/intit.d/ (you may use cp -v source destination or mv -v source destination)
4. Make your copied script executable by using chmod +x startup
5. then type the following commands update-rc.d startup defaults

INSERTING A SCRIPT AFTER LOGGING IN

1. Doing this is as easy as doing it in Windows
2. Go to System->Preferences->StartUp Applications
3. Click Add
4. Write your App’s name
5. Make sure your app is executable and provide a link to it in the command prompt
6. You can also a bash command in command dialog box
7. Enter a description if you want to
8. Click Ok and you are done…
