Have wc work on each file then add up the total with awk; get a 43% speed increase on RHEL over using "-exec cat|wc -l" and a 67% increase on my Ubuntu laptop (this is with 10MB of data in 767 files).

use find to grep all .c files from the target directory, cat them into one stream, then piped to wc to count the lines

Know a better way?

If you can do better, submit your command here.

What others think

wc can take multiple files as arguments, so you REALLY want to replace \; with +, enabling the "xargs mode" of the -exec option:

find . -type f -name "*.c" -exec wc -l {} + | awk '{t+=$1} END {print t}'
Comment by bwoodacre 193 weeks and 4 days ago

The "+" option is not a standard feature of find. Not all versions of Linux will support it, let alone the different flavors of UNIX out there.

Comment by arcege 193 weeks and 4 days ago

That's too bad since I find + so useful and have recommended it to so many on commandlinefu! Although for really kinky things you want xargs which more systems have, so I can see why "feature duplication" is avoided by some.

I tested it on Redhat, Ubuntu, and Debian and it works there. What non-dead UNIXes do not support the feature? I haven't been very successful at googling.
