I'm trying to setup a script in my .bashrc which would create an alias that makes it possible to run a command in the background and ignores output. It should be possible for this command to have multiple arguments, for example "java -jar MyJar.jar". So far I have tried: alias back='nohup "$1" > /dev/null &' But when I test it using for example back sh path/to/intellij/bin/idea.sh my console output is like this: nohup: failed to run command ‘’: No such file or directory And whenever an error happens, it's also logged, which is what I wanted to avoid. Am I taking the wrong approach here or what is going on?

You will need to use a function instead of an alias like:

function back() {
    nohup "$@" &> /dev/null &
}

  • What does the &> /dev/null do here? doesn't the nohup command itself capture all the output into the nohup.out file already? Commented Aug 19, 2016 at 10:18
  • It prevents the output of nohup: ignoring input and appending output to ‘nohup.out’

  • Adding this to .bashrc was indeed the solution, and works like a charm.
