How to start a GUI application from the terminal and return immediately? [duplicate]
For example, if I type gimp in my terminal, Gimp will launch, but it will wait for gimp to be closed before returning control to the terminal. If I press CtrlC it will close Gimp. How do I prevent this?
place an ampersand (&) at the end of the command, e.g.:
gksu nautilus &
to start a root file manager, or in your case, to start GIMP:
gimp &
It's really as simple as that!
