The problem is that if I execute a command (eg. a Python script), the terminal or script is waiting until the program return a exit status so that it can continue or return to terminal. Is there a way to circumvent this?

  • You could run it in the background, just do: ./command.py & – jgr Jan 14 '13 at 20:00

In most shells, you can launch commands or processes in the background by appending an ampersand (&) to the command:

python file.py &

Several choices:

  1. Run it in screen. man screen, screen, myprorgamm, C-a d, screen -r.
  2. nohup myprogramm
  3. myprogramm &
  • Tried: $ screen _command_, $ nohup _command_ $ _command_ &. Nothing worked so far. – user1527118 Jan 14 '13 at 20:19

    for screen - start with man screen, it's complex app with lots and lots of functionality. nohup and & (aka detach) can't "not work", really. if there is any error - make sure to post it here. – iced Jan 14 '13 at 20:23

  • What OS and shell are you using? – Ivan Yurchenko Jan 14 '13 at 20:05
  • Trisquel GNU/Linux with dash. In Terminal I am using bash, while in scripts dash. Either of these does not work. The command I am trying to execute is /usr/share/screenlets/CircleClock/CircleClockScreenlet.py which is a part of a program called Screenlets (also available in Ubuntu). – user1527118 Jan 14 '13 at 20:13
