Running bash commands in the background without printing job and process ids

Question

To run a process in the background in bash is fairly easy.

$ echo \"Hello I\'m a background task\" &
[1] 2076
Hello I\'m a background task
[1]+  Done             


        

Answer 1

Based on this answer, I came up with the more concise and correct:

silent_background() {
    { 2>&3 "$@"& } 3>&2 2>/dev/null
    disown &>/dev/null  # Prevent whine if job has already completed
}
silent_background date
