Apply icons to bash scripts

I created a script for XChat according to this answer, and I was wondering if there is anyway to apply XChat icon to it.

Solution 1:

Create a .desktop file like this and put it in /usr/share/applications/

[Desktop Entry]
Type=Application
Name=XChat Firefox
Exec=/usr/bin/your_script
Icon=/usr/share/icons/xchats_icon

"XChat Firefox" will then be a launchable application with XChat's icon. Exec can also take a bash command (with arguments, optionally) as its value.

For a complete explanation of the .desktop format, see this specification.

Solution 2:

After copying your appname.desktop file to /usr/share/applications you may have to wait a few minutes while kbuildsycoca4 rebuilds the system config cache.
