Launch independent process

How can I close a terminal without killing the command running in it?

If I open a terminal emulator, type firefox & and then close the terminal, the process it launched -Firefox- gets killed as it was its child.

How can I prevent this behavior?

in any case, for most cases a "Run program..."-style launcher will do. — deprecated, May 13 '12 at 17:16

Use the disown command. In zsh you can also use &| to background and disown in a single operation.

$ firefox &
[1] 74773
$ disown %1 # or "disown %firefox"
$ firefox &| # zsh only; bash will report "syntax error near unexpected token `|'"

cool! apparently one can't do it in one line right? will consider switching to zsh. – deprecated May 13 '12 at 17:31
I couldn't find one, sadly. Possibly someone more expert in `bash` knows a trick, other than a shell function that manipulates job control to do it. – geekosaur May 13 '12 at 17:35
@vemv try `nohup`. Example - `nohup firefox` – Ulrich Dangel May 13 '12 at 21:22
