I'm sure none of you care much but I'm quite pleased I was able to figure this out in only a couple tries**
ETA: fixes, works well though there is still some error junk in the output, even with the 2>&1 > dev/null incantation.
**The hours wasted fighting with gem, ImageMagick, macports (sudo mv /opt/not.opt), and make last week will not be spoken of. Take one point from ruby and put it into bash's bucket.
