What Others Think

Nice trick with the % ${name%ext}. I looked it up: http://www.gnu.org/software/bash/manual/bashref.html#Shell-Parameter-Expansion Using the rename command that comes with the "util-linux" package in almost every linux distribution: rename .ex1 .ex2 *.ex1 the asterisk must be unquoted because rename depends on the shell to expand *.ex1. Another way, using the prename command that comes with perl: rename 'y/ex1/ex2/' *.ex1

I got it from somewhere -- maybe The Bash Cookbook? At any rate, it's been tremendously useful. I've stayed away from rename versions since I spend considerable time on OS X and OpenSolaris where rename isn't as ubiquitous.
