Functions: cat find wc

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

find . -type f -name '*.c' -exec wc -l {} \; | awk '{sum+=$1} END {print sum}'

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).

Know a better way?

If you can do better, submit your command here.

What others think

Use find's "xargs mode" and (I just looked this up now) you can use awk to avoid tail if you must just only print the sum and not the word "total" :

find . -name \*.c -exec wc -l {} + | awk 'END {print $1}'

in awk, END is true at end-of-file (after the last line).
