bash find and move script

test data:
========
$ find -type f
./foo/bar3
./foo/blah3.jpg
./foo/blah2.JPG
./blah.JPG

script:
========
# the next IFS= line makes the find work for spaces,
# so only new lines in find output will separate file names
IFS=$'\n'
for name in $(find -type f -name "*.JPG"); do
     oldname=$(basename "$name")
     dir=$(dirname "$name")
     newname=$(echo "$oldname" | sed -r "s/\.JPG/.jpg/")
     echo "mv \"$name\" \"$dir/$newname\""
done
