Regex Therapy: Rename / Ack / Perl CLI
Learn regular expressions through practical command-line tools. Master ack for searching, rename for bulk file operations, and Perl one-liners for text transformation. Same syntax across all three tools. No theory dumps, just patterns you can use today.
Heads up!
This tutorial was created on 2026-01-15 and everything
was tested and working at that time. Technology moves fast though, and software
updates can break things. No guarantees that every step still works exactly
as written. When in doubt, check the latest docs for the tools involved.
