AppleScript to Make Filenames Unique

I needed this when I import photos from several sources and they have overlapping names. Simply select all the files and execute this script, probably from the User Scripts Folder.

Inside the AppleScript editor (in your OSX Applications - Utilities) go to Preferences - General and check

[x] Show Script menu in menu bar

# AppleScript (multi) rename script for Finder files.
# Hens Zimmerman, October 16, 2011.
 
# Iterate through all files and rename them.
 
tell application "Finder"
    set filenames to selection
    set theCount to number of items in filenames
     
    repeat with idx from 1 to theCount
        set theFile to (item idx of filenames as text)
        set TheName to name of (theFile as alias)
        set UUID to do shell script "uuidgen"
        set NewName to (UUID & " " & TheName)
        set name of file theFile to NewName
    end repeat
end tell

Now in the OSX Finder, simply select the files you want to give a unique filename and execute the script.
