Hi there,
Hi
I have a bunch of files that I want to rename:

There's no regex anywhere in your examples, only "globs" aka shell pattern matching aka shell pathname expansion. See here: http://mywiki.wooledge.org/glob http://mywiki.wooledge.org/RegularExpression It's important to understand that these are distinct things. They superficially might look similar, but they behave differently. regex is more powerful, and more complicated. A perl-based solution will require you to use regex notation. A solution using 'find' and 'mv' with shell parameter expansion (like your example) http://mywiki.wooledge.org/BashFAQ/073 will require you to use glob notation. So a first step might be to choose which of regex or glob you prefer, and then proceed from there. Your problem statement looks simple enough that regex is not required, unless you choose an approach that mandates using regex. Personally being already comfortable with both, I would probably use a perl-based "rename" tool. It has a dry-run option which is useful when you are unsure of the syntax.
