What Others Think

Why not: nohup /bin/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 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 >/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.
