This command runs your shell script in the background with no output of any kind, and it will remain running even after you logout.

What others think

Why not:

nohup /bin/sh myscript.sh >/dev/null 2>&1 &

I even think it's not needed to redirect stdout here because nohup does redirect stdout to file "nohup.out", so this might be enough:

nohup /bin/sh myscript.sh 2>/dev/null &

I could not verify this at the moment, but the other version has quite many redirects.

Or am I wrong ?

I'm pretty sure you can even do it this way too which wont create a nohup file:

(/bin/sh myscript.sh >/dev/null 2>&1) &

ya the goal was to not create a nohup and display no message, it worked but you guys are right, the nohup is not neccessary... I think I just liked the nohup as it avoided the subshell problems.

what is up with the repeated redirection?
