find . -type f -exec cat {} \; | wc -l
using xargs makes the command complete in 1 second:find . -type f | xargs cat | wc -l
Anytime you find yourself using a loop with find, there's a possibility that xargs could be helpful and a lot faster.find . -type f | xargs wc -l
find . -type f -exec cat {} + | wc -l
You see, if you use the \;, that would be the same as doing(cat file1; cat file2; cat file3 ... ) | wc -l
but with the +, it's the same as doingcat file1 file2 file3 ... | wc -l
That gets more to the real point of cat (concatenate, not print).
