What others think

Actually, at one point I used this very simple command on my Eeepc to write a bash daemon to monitor the VGA connector, and automatically set up this sort of thing. This accomplishment was both my first real shell script, as well as my first contribution to open source (i was so proud when someone found it useful enough to make it work better ^.^)
