Can you batch rename files if they contain certain criteria

You might want to try the application A Better Finder Rename. It has a built-in function to convert Mac file & folder names to legal Windows file & folder names:

Naturally, somebody will come along later and throw a smattering of regex in a bash script for you to puzzle out, but ABFR does this kind of thing so easily. It can even create a droplet app onto which you can 'drop' files & folders to be processed. It is a handy tool to have in your toolbox if you aren't a strong programmer, or don't have the time, or both.

Try something like this:

 for file in Picture*.jpg
 do
    mv "$file" "vacation-$file"
 done  

(open terminal and add one line {press Enter} at a time.)

What that does is uses the variable file for each entry matching Picture*.jpg. Then it takes the file or folder and moves it to be prefixed with "vacation".

Hope that helps
