Simple bash approach. But this script will clobber files when there is a collision: e.g. What if you have John jOhn JOHN john joHN?
You could do the same with the rename command, which does account for collisions. See man rename(1)
#! /bin/bash
#
# Changes every filename in working directory to all lowercase.
#
# Inspired by a script of john dubois,
# which was translated into into bash by Chet Ramey,
# and considerably simplified by Mendel Cooper,
# author of this HOWTO.
for filename in * #Traverse all files in directory.
do
fname=`basename $filename`
n=`echo $fname | tr A-Z a-z` #Change name to lowercase.
if [ $fname != $n ] # Rename only files not already lowercase.
then
mv $fname $n
fi
done
exit 0
