how to let wc command recursivly ?

Question

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

Answer 1

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

Answer 2

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.

Answer 3

bash 4

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