I want to calulate the total line numebers of the files(*.h *.cpp) in certain directory(include its subdirecories). How to I write the command? cat ./tmp/*.h | wc -l

maybe wc -l `find -iname "*.h"`

The command you written does not work.

cat a/*.h a/*.cpp | wc -l
but cannot include the subdirectories.

sloccount?

Try:

find . -name "*.h" -o -name "*.cpp" | xargs wc -l
