Here's something trivial. Replace ... with a comma-separated list of
sub-directories to look in. I use .x and .y for lex and yacc files.
The first output is just the line (word, character) count output from
wc. The second output is the wc output from "blank or comment" lines.


#!/bin/csh -f
set dirs='{...}'
set files="$dirs/*.[chxy]"
wc $files
echo "blank-or-comment lines:"
grep -h '\(^$\)\|\(^ \*\)\|\(^[ ]*/\*\)' $files | wc
