Re: help with 'rename' function

Well, I needed to do exactly this but also do other arbitrary
rename operations to one or many files, so I first created a
"higher-order" ;) function...

rename-with-filter () {
        if ! [[ $# -lt 2 ]]
                for kala in $argv[2,-1]
                        mv "$kala" "$(echo "$kala" | eval $1)"

...using which I could make, for example, a following kind of
function to transform filenames like ThisIsFilename to

rename_separate () {
        rename-with-filter "sed -e 's/\([a-z]\)\([A-Z]\)/\1_\2/g'" $*

This should handle your much simpler case too.

Sorry, can't help you with your implementation, I'm pretty much
write-only zsh user :)
