bash: make rename script traverse directories

Hi, I have written a simple script to rename a load of files from *.pdf to *_.pdf.

The problem I have is that it can't traverse directories, as I have several hundred directories and I don't fancy running the script manually in each one. I have 3 levels of directories that I need it to look in - basically it just needs to do so recursively.

Here is the script:

Quote:

#!/bin/bash

for i in *.pdf
do

j=`echo $i | sed 's/.pdf/_.pdf/'`
mv $i $j

done

It works fine when run from within the folder containing some pdf's, but I can't run it from 1 level up, i.e. encompassing a couple of hundred folders each containing 10's of pdf's.

Any help would be greatly appreciated.

try

Code:

find . -name '*.pdf' | while read f

do

  echo mv $f ${f%.pdf}_.pdf

done

using echo for safety.

try this:

Code:

for i in `find . -name '*.pdf'`
