i need to change string in all files in current folder and all subfolders. i wrote the following script. It works good except it dont delete temp file from subfolders.

for z in `find . -type f -name "*.html" -o -name "*.htm"`; do
sed -e 's@abc@xyz@g' $z>temp;
mv temp $z;
done

any idea? or any other better solution?
