Some GUI apps launch cleanly via the Terminal command line, but some don't, and they cause the Terminal to wait for the app to terminate. Even then, some don't "release" the command line.
The mysterious ampersand
& suffix seems to cause the terminal to put the process into the background (but I'm not sure what happens there).
Is there a way to launch an app via the Terminal so that there is no "hang on" effect, just like launching something via Alt+F2?
I'd like to have the command line available again immediately, without something still in the background and printing in the terminal.
