Filenames ROT13

for each in *; do file="$each."; name=${file%%.*}; suffix=${file#*.}; mv "$each" "$(echo $name | rot13)${suffix:+.}${suffix%.}"; done
This got a bit complicated, because I had to introduce an additional dot at the end that has to be removed again later.

What Others Think

This is a bit shorter and simpler: for i in *;do mv "$i" "$(echo ${i%%.*}|rot13).${i#*.}";done

eightmillion: Yes, but it doesn't work for filenames without a dot.

Ahh, right. I hadn't considered that. Your version suddenly makes way more sense.
