Counting lines of code

So a few years ago, me and a coworker had to figure out how many lines of code we had. This was either for metrics or for because we were curious, I can’t really remember why. I came across the script again today while going through some old code. Here it is in all its glory:

#!/bin/bash

let n=0; for x in "$@"; do temp1=`find $x | grep '\\.cpp$\|\\.c$\|\\.java$\|\\.cc$\|\\.h$\|\\.xml$\|\\.sh$\|\\.pl$\|\\.bash$\|\\.proto$'`; temp=`cat /dev/null $temp1 | grep -c [.]*`; let n=$n+$temp; if [ $temp -gt 0 ]; then printf "%s: " $x ; echo $temp; fi; done ; echo Total: $n

This took us at least an hour(or perhaps more), I’m not really sure.

Anyway, it was after we had done all of that work that we realized that wc exists.
