Thanks for the response. I tried a test case with the code you gave and the filenames don't change.
Code:
#! /bin/bash

for OLD_FILE in $( ls | egrep '^[0-9]{5}' )
do
  NEW_FILE=$( echo ${OLD_FILE} | sed 's/^[0-9]{5}//' )
  if [ -f $NEW_FILE ]
  then
    echo $NEW_FILE'-duplicate'
  fi
  echo $OLD_FILE $NEW_FILE
done

exit 0

The code I think is not working is: ( echo ${OLD_FILE} | sed 's/^[0-9]{5}//' )
Any thoughts?
