Regular Expressions With GNU grep in the Terminal - Part 01 [Learn by Practicing]

Regular expressions (or regex) is a powerful tool to match patterns of text. This video is the first part of a series on regular expression with Grep, with practical cases and exercises for you to understand how it works. I'm using GNU grep. Other implementation of grep might be a bit different. You can't use Perl regex (-P option) with BSD grep for example (by default on MacOS). However, what I demonstrate in the video should work with the Extended regex flavor too (-E option). A little mistake: pgrep is NOT grep -P ⌨ Follow along with these files: https://github.com/Phantas0s/mouseles... 📙 Building Your Mouseless Development Environment: https://themouseless.dev 📑 Learning to Play Vim: https://themouseless.dev/vim 💎 Increase your value as a developer: https://thevaluable.dev 🐙 Github: https://github.com/Phantas0s 🍒 Support the channel: https://github.com/sponsors/Phantas0s Chapters: 00:00 How to follow along with me 01:51 Regex with Grep, metacharacters, and escaping 04:10 Regex flavors (Basic, extended, and Perl regex) 07:57 egrep / fgrep / pgreg 09:10 Matching a word ("\b" or "-w") 11:10 Matching from the beginning of the line ("^") 13:08 Matching till the end of the line ("$") 14:24 Exercises 17:37 Matching any character with "." 20:14 Matching whitespaces using "\s" 21:16 Character class "[ ]" 24:19 Exercises 27:18 Thanks!
