One way is to use recursion (btw, my previous script had an error: tr
must be invoked without the -s option):
#!/bin/bash
# $1 is the file/dir name
function change_case() {
newname=`echo $1 | tr 'A-Z' 'a-z'`
echo "$1 -> $newname" # for debug
mv $1 $newname
}
function scan() {
local i
for i in $*; do
if [ -d $i ]; then
# $i is a directory, recurse and change case
cd $i
scan *
cd ..
change_case $i
else
# regular file
change_case $i
fi
done
}
# start
if [ $# -eq 0 ]; then
echo "Must specify root directory"
exit 1
fi
shopt -s nullglob # to account for empty dirs
cd $1
scan *
exit 0
