Show HN: Interactive exercises for Linux CLI text processing commands Last month, I started learning a Python TUI framework called Textual. After working on a 4x4 board game, I made an interactive app to test your CLI text processing skills with 40 beginner to intermediate level exercises. The app is fairly basic in terms of features — only single input file, so no stdin data, multiple files, etc. Most of the exercises in this app is based on my Computing from the Command Line ebook ( https://bit.ly/3fyzcaX ). I hope to improve the TUI app to support all the 200+ exercises sometime next year. https://bit.ly/3PeviBm December 10, 2022 at 12:19PM
