Zsh trick: restart pow with command completion

Recently I started using the zero configuraiton web server pow from the good folks at 37signals and absolutly love it. I really like how restarting the server is as simple as touching restart.txt to the tmp directory. However I have been working on a feature that requires frequent restarts of the server and found it repetitive. Since I was being lazy about typing in the path to restart.txt I decided to automate it a little. And add command completion.

Got those with the following zsh script:

kapow(){
  touch ~/.pow/$1/tmp/restart.txt;
  if [ $? -eq 0 ]; then; echo "pow: restarting $1" ; fi
}
compctl -W ~/.pow -/ kapow

This gives me a kapow command that will restart the app for me.

I also put it up in a gist, if you would like to fork it and make changes.
