ps wwwwuax|awk '/command/ { printf("kill -9 %s\n",$2) }'|/bin/sh

Kill all processes belonging to a user

Okay, commands like this are a bit of a personal peeve. awk(1) operates on a /pattern/ {action} paradigm and yet I see people leave out the /pattern/ portion of an awk command all the time, opting to use grep or sed instead. You'll save yourself some typing and time if you include the /pattern/ with your {action}.

What Others Think

Not bad, but you can save a few characters by changing printf to print: 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.
