Can I batch rename to remove prepended characters?

Question

I know the basics of batch renaming files, but can't seem to figure out if this is possible:
I have a number of files scattered across different projects and folders.
These files are named ABC-DEF-xxxxxxx
The xxxxxxx is unique to each file, and non-sequential (sometimes just text words).
So I am wondering is if there a way to batch remove the "ABC-DEF-" from the master file name and leave everything else in the name unchanged?
I should say...without doing a tremendous amount of work like exporting the files from Aperture, changing the names somehow, then re-importing (which I think would be lots of work, esp since the files are scattered across different projects/folders).
Thanks much everyone!

Answer 1

This script will rename all the selected versions in the form XXX-YYY-FinalName to FinalName
Doesn;t matter what XXX and YYY are or how long they are as long as the format is exactly three groups of chars separated by a dash.
tell application "Aperture"
          set imageList to (the selection)
          if imageList is {} then
                    error "Select IMages."
          end if
          set {oldTID, AppleScript's text item delimiters} to {AppleScript's text item delimiters, "-"}
          repeat with i in imageList
                    set n to (name of i)
                    set name of i to text item 3 of n
          end repeat
          set AppleScript's text item delimiters to oldTID
end tell
to run it select all the text in the box above right click it and select make new applescript. This will copy the script into the AppleScript editor.
Start Aperture and select the images you want to rename.  I strongly advise you do this first on a test library to make sure it is doing want you want. Export some of the images as a new library and test with that.
Note this will only change the version names no the original file names. If you also want to change the original file names once the versions are renamed select them and run  MetaDatat->Batch Change. Select Version Name Format: Current Version Name and select the Apply to Originals checkbox.
