Eject and the autamated cat feeder.

I was teaching a Linux system administration course last week at College of Engineering Chengannur. While  I was demonstrating openssh one of the participants logged on the my demo machine remotely and  ejected the cdrom drive with eject. He then asked me how to close the drive from command line. I said i don’t know. Today, I  searched the net for a solution and found out that eject -t can close the cd drive. ( eject has a couple of other interesting options . RTFM eject)

While searching for this information I landed on a funny project called automatic cat feeder. The cat feeder is built with ubuntu linux and this guy has made the most innovative use of eject utility. 😀
