How can I prevent nohup from creating the file ~/nohup.out?

  • 772

I use the command $ nohup ... to start an application in the background so that I can close the terminal window afterwards.

Upon execution it creates the file ~/nohup.out.

Example:

orschiro@x230:~$ nohup /bin/bash -c "sleep 15 && python3 /home/orschiro/bin/show_state.py"
nohup: ignoring input and appending output to 'nohup.out'

How can I prevent nohup from creating nohup.out?

command-line

    You may redirect the output anywhere you like, for example:

    nohup /bin/bash -c "sleep 15 && python3 /home/orschiro/bin/show_state.py" >/dev/null 2>&1

    redirection prevents the default output file nohup.out from being created. /dev/null is oblivion, so if you don't want the data at all, send it there.

    In bash you can abbreviate >/dev/null 2>&1 to &>/dev/null

    For programs I use often I make an alias (and add it to my .bashrc) for example

    alias show_state='nohup /bin/bash -c "sleep 15 && python3 /home/orschiro/bin/show_state.py" >/dev/null 2>&1'

    Now all I have to type is show_state
