Grep multiple current extension and subfolders

Question

I am trying to grep several extensions in the current and all subfolders.

grep -i -r -n 'hello' somepath/*.{php,html}

This is only grepping the current folder, but not subfolders.

What would be a good way to do this?

Answer 1

One of them:

find '(' -name '*.php' -o -name '*.html' ')' -exec grep -i -n hello {} +
find '(' -name '*.php' -o -name '*.html' ')' -print0 | xargs -0 grep -i -n hello

Answer 2

Using grep only:

grep -irn --include='*.php' --include='*.html' 'hello' somepath/
