Nicely done! The 'killall' command might also be worth mentioning:
$ killall vim
But I think it'll be less specific as your method (but handy if you know for sure the process is
exactly called 'vim')
Also, maybe persons less familiar with awk could use 'cut -f 2' to get the processid.
again, great stuff

You can use pgrep/pkill for this, if it's installed on your system:
pgrep prog.*1
pid
pid
pid
pkill prog.*1
will kill all the pids matching the pattern.
