I have 91 photos that I want to rename in this fashion. Thanks!

hi, can you teach me how to do it ? I know about "for f in `ls *.jpg` ; do mv "$f" "01_$f" ; done, but how can i set 01 to increase by a value of 1 until 91? Also, it has to be 01 and not 1. Thanks! — user2494805, Jun 17 '13 at 20:18

A simple for loop to iterate over the files and printf to make the new filename should do it:

#!/bin/bash

i=1
for orig in *.jpg
do
    new=$(printf "%02d_%s" $i $orig)
    mv $orig $new
    ((i++))
done
