This is a 'killall' command equivalent where it is not available. Prior to executing it, set the environment variable USERNAME to the username, whose processes you want to kill or replace the username with the $USERNAME on the command above. Side effect: If any processes from other users, are running with a parameter of $USERNAME, they will be killed as well (assuming you are running this as root user) [-9] in square brackets at the end of the command is optional and strongly suggested to be your last resort. I do not like to use it as the killed process leaves a lot of mess behind.
kill processes by user . Remove "i" if you don't want to confirm.
Kill all processes belonging to a user, with a minimum of resource usage. Great for the times when a user fork-bombs the system and it's difficult to login or run commands.
Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?

ps wwwwuax|awk '/command/ { print "kill -9 "$2 }'|/bin/sh
Then another few by using a subshell execution rather than the pipe:kill -9 $(ps wwwwuax|awk '/command/ { print $2 }')
This works, but it exposes a bug in the original command. Awk's pattern matches awk itself. In the original command the error message is lost.
