Im afraid, that output has no files that match your criteria - maybe the typo of ".jpp" in your original request should have been ".jpg" ?

@citaylor - thanks very much for your help - that worked like a charm! Smilie

Now that I have a list of these files is there someway I could create a pairing file which I could execute and have all the files renamed as would specified by the pairing file?

    print;
  }
}

this is bad. do not shell out unless you absolutely have to. In Perl , you can use
Code:
while (<*>){
   ....
}

to display files

    echo $file
  fi
done

another bad example. Don't use ls to parse files. use the shell
Code:
for file in *
do
  ....
done

@citaylor - well i would ideally like to be able to create a flat file in the form of:

[name of file to rename] | [new file name]

and then execute some sort of script that will apply the renaming to the files that exist in a specific folder.

again many thanks for your help

Is there a predefined list of these renames, or is there an algorithm we could use to know what to rename the files to ? The latter is easier, but the former isnt difficult either...

@citaylor - there is a predifined list which I would like to use - an alogorithm would be nice to use however as many of these files have been in correctly named by hand it would be very dificult to create an algorithm that would be able to do the matching automatically
