Let it counting *.h *.cpp in Sub directory.

---

If you want it seperate per file:

find -type f \( -name "*.h" -o -name "*.cpp" \) -exec wc {} \;

if you want the accumulated sum:

find -type f \( -name "*.h" -o -name "*.cpp" \) -exec cat {} \; | wc -l

bash 4

shopt -s globstar
wc **/*.{cpp,h}

---

I think find and xargs is clearer and easier to work with instead of find -exec but it's style choice.

find . -name "*.h" -or -name "*.cpp" | xargs wc

---

Use zsh instead of bash:

wc **/*.(cpp|h)

This will expand out to all the .cpp and .h files in the current directory and all subdirectories.
