There are many guides and books for learning sed, but few are interactive. The goal of this project is to provide a number of lessons with real text files to learn and experiment with. It is self contained and does not require writing your own example data.

I am not an expert on sed, but want to learn more about it.

This guide is for people who want to learn sed. You have some familiarity with unix system and using the command line. You have a basic understanding of regular expressions.

Clone this repository.

git clone [email protected]:josefalcon/learning-sed.git

Each lesson is in a separate directory with an example file and a README. cd into the lesson folder, and start learning sed!
