my personal tool to count source file lines. This is Shell version

countline

#!/bin/bash

# write to count the sourcefile 

w=0
par=$3
origin=2
echo "${par:=$origin}"

for s in $(find $1 -maxdepth ${par:=$origin}  -type f -name "*.$2")
do
	t=$(wc -l $s | awk '{print $1}')
	echo -e "$s: \e[1;32m $t \e[0m"
	let  "w=w+t"
done

echo -e "\e[1;31m total:\e[1;32m $w \e[0m"
