Recipe 8.8. Killing User Processes the Easy, Fun Way

8.8.1 Problem

You need to delete a user, but userdel reports that some of the user's processes are running. You sure would like single command to find and stop all of the user's processes.

8.8.2 Solution

Use the slay program:

# slay foober

slay: -KILL is kicking foober's butt!

slay: Whoa, I have the power supreme.

slay finds and kills all the user's processes at once, saving you the trouble of hunting them down and killing them yourself. slay has four modes: nice, normal, mean, and butthead. Mean mode kills any nonprivileged user who attempts to slay another user. Set your desired mode in /etc/slay_mode.

8.8.3 Discussion

The traditional method of finding processes belonging to a user is to use ps, as in:

$ ps U 1007


$ ps U foober

3936 ?        S      0:00 xchat

3987 ?        S      0:00 /usr/lib/galeon-bin

4209 ?        S      0:00 kdeinit: kio_file file /tmp/ksocket-carla/klauncherkF21rc.slave-

You can then kill one by one:

# kill 3936

# kill 3987

# kill 4209
