Kill all processes that don't belong to root/force logoff

for i in $(pgrep -v -u root);do kill -9 $i;done
explanation: grep -- displays process ids -v -- negates the matching, displays all but what is specified in the other options -u -- specifies the user to display, or in this case negate The process loops through all PIDs that are found by pgrep, then orders a forced kill to the processes in numerical order, effectively killing the parent processes first including the shells in use which will force the users to logout. Tested on Slackware Linux 12.2 and Slackware-current

What Others Think

This would be a good place for xargs pgrep -v -u root | xargs kill Or, even better, just use pkill pkill -v -u root

Thank you for pointing out the other commands. I will test them to see if they yield the same results including forcing the users to be logged out.
