how to use sed to replace text in subfolders

Question

i use this code to replace some text in an HTML file:

sed -i 's/tttt/new-word/g' /home/zjm1126/*.html

This doesn't search for files in subfolders, though. How do I apply this command to subfolders?

Answer 1

find /home/zjm1126/ -name '*.html' -print0 | xargs -0 sed -i 's/tttt/new-word/g'

Answer 2

Can you try somthing like

for z in `find /home/zjm1126/ -type f -name "*.html"`; do
sed -e 's/tttt/new-word/g' $z>temp;
done
