Here's mine:

#!/bin/sh
flags="-TERM"
case $1 in -*) flags="$1"; shift;; esac
patterns="evilfuckinghack"
for n in $*
do
  patterns="$patterns|$n"
done
killed="`ps ax|awk '$5 ~ /'$patterns'/ {print $1}'`"
test -z "$killed" && exit 1
echo $killed
kill $flags $killed
exit $?

And you're right. It *is* incredibly useful.
