  • I took java to make the find command simpler and to state that it works for any language supported by cpp. cpp is the C/C++ preprocessor (interprets macros, removes comments, inserts includes, resolves trigraphs). The -fpreprocessor option tells cpp to assume the input has already been preprocessed so it will only replace comment lines with blank lines. The -L 1 option tells xargs to launch one process for each line, indeed cpp can only process one file at the time...

    find . -name '*.java' | xargs -L 1 cpp -fpreprocessed | grep . | wc -l

What Others Think

You don't need grep . in there. `xargs wc -l` works just fine.

Why is this useful? Looking to brag about the amount of code you've written? Hoping to impress your boss on the next yearly review? LOC mean nothing to your ability as a programmer.

find . -name '*.php' | xargs wc -l says the total is 1564, but find . -name '*.php' | xargs grep . | wc -l says it is 1161...

@atopnce: indeed but code volume can be an interesting information, for instance when you've just been handed a code to maintain
