A small collection of tiny command-line programs written in Perl.

This repository starts with a minimal wc implementation and will grow with other familiar Unix-style tools such as ls. The goal is to learn Perl by rebuilding small utilities, keeping each program readable enough to explain in short posts.

Counts basic file statistics.

perl wc.pl file.txt

Prints:

<lines> <words> <file>

Line-only mode:

perl wc.pl -l file.txt

Prints:

<lines> <file>

• Perl 5.36 or newer

This is a learning playground: small Perl programs first, then posts explaining what each one teaches about Perl, command-line interfaces, and Unix tools.
