how to put particular application on system startup in fedora 15? How do I put particular application on system startup on my Fedora 15. For instance if I want to start my Firefox browser on system startup how do I achieve this? What have I done so far is, I just created a simple shell scrip and put the command of starting a Firefox browser in that and placed that shell script in `/etc/init.d/` directory. #!/bin/bash /usr/bin/firefox

That should be configured in your desktop environment (DE) settings. For example if you're running Gnome, use `gnome-session-properties` as explained in this question on AskFedora.

For KDE this can be configured in `Autostart`, which looks like this:

The reason why the global init scripts won't work is that these commands are run outside the scope of the GUI/DE. Similarly, you can't run `firefox` from a plain tty shell without tweaks, but you can from the terminal window within your DE.
