That's great - be insulting.

But just in case you aren't as stupid as you seem, I'll take the above
as real.

First, you need to know how to create a shell script. See
http://aplawrence.com/Basics/scripting.html if you don't.

Next, you need to count lines. Start with "man wc". You need to
differentiate between comment lines and non-comment lines: "man grep".

But if you really want to impress your professor, I'd suggest you
submit an alternate solution using the shell's "read" function, and
"test" and "expr" (or built in math if you are allowed to use bash or
ksh). Finally, you should do one in awk and one in Perl.

You should look at "man bc" and "man dc" also, just for completeness.
If you really investigate all I've suggested here, you'll learn quite a bit.
