Throw an exit code when no players are running

[UtkarshVerma]

I was currently writing a script for displaying playerctl details in i3bar and wanted to develop a case where the script shouldn't execute, that is when no players are active. My first thought was to use the playerctl status command and match it with "No players found" and it worked, but I wasn't able to suppress the excess output associated with it, that is "No players found". I also checked if playerctl throws an exit code when executing playerctl status in absence of any music players, and it doesn't. It always exits with zero exit code.
Therefore it would be great if the functionality of returning an error code other than 0 were implemented since that would enable me to use the following:

#Exit script if no players running
playerctl status 2>/dev/null || exit 3;

Yeah seems reasonable.

In the meantime:

if [[ $(playerctl status 2>&1) = "No players found" ]]; then
    exit 3
fi

@acrisci Thanks, that's quite similar to what I'm using as a workaround currently. But better since it doesn't rely on grep.

[[ $(playerctl status 2>&1 | grep "No players found") = "" ]] || exit 3;
