I am running jupyter lab 4.4.0 on redhat 6. I am trying to start the lab in the background so that the app\'s output is not appearing in my console anymore.
$ jupy
You should rewrite your command like this:
$ jupyer lab >/dev/null 2>&1 &
ANd also is wise to add nohup to avoid stop of app if you logout
$ nohup jupyer lab >/dev/null 2>&1 &
