Old-Schcool UNIX Script: Clean House
The hard drives on the Silicone Graphics IRIX systems that I used to administer were always filling up. We had plenty of hard disk space, for the time, but the systems were used in ways that quickly ate up any available space. Some of the workstations were used for running engineering analyses that could generate humongous result files, while others ran CAD applications which left behind many medium-sized temporary files. To keep the systems running it was necessary frequently clean up the drives, and since manually cleaning up disks can be error prone I wrote a script to do the work for me. Since I wrote the script to do some of my work for I had a little free time to add a nifty progress display, which makes the program slightly more complex.
