Schedule a script or command in x num hours, silently run in the background even if logged out

echo "nohup command rm -rf /phpsessions 1>&2 &>/dev/null 1>&2 &>/dev/null&" | at now + 3 hours 1>&2 &>/dev/null
This is helpful for shell scripts, I use it in my custom php install script to schedule to delete the build files in 3 hours, as the php install script is completely automated and is made to run slow. Does require at, which some environments without crontab still do have. You can add as many commands to the at you want. Here's how I delete them in case the script gets killed. (trapped) atq |awk '{print $1}'|xargs -iJ atrm J &>/dev/null

You don't need nohup for at-jobs, and you don't need do redirect STDIN and STDERR either (will be sent by mail to the user that starts the job)

What's up with the double redirection? So it seems like the shorter version would be: echo "rm -rf /phpsessions" | at now + 3 hours

echo overload! (attempt #2 :-) <<< "rm -rf /phpsessions" at now + 3 hours
