Show HN: I wrote a modern Command Line Handbook

TLDR: I wrote a handbook for the Linux command line. 120 pages in PDF. Updated for 2025. Pay what you want.

A few years back I wrote an ebook about the Linux command line. Instead of focusing on a specific shell, paraphrasing manual pages, or providing long repetitive explanations, the idea was to create a modern guide that would help readers to understand the command line in the practical sense, cover the most common things people use the command line for, and do so without wasting the readers' time.

The book contains material on terminals, shells (compatible with both Bash and Zsh), configuration, command line programs for typical use cases, shell scripting, and many tips and tricks to make working on the command line more convenient. I still consider it "an introduction" and it is not necessarily a book for the HN crowd that lives in the terminal, but I believe that the book will easily cover 80 % of the things most people want or need to do in the terminal.

I made a couple of updates to the book over the years and just finished a significant one for 2025. The book is not perfect. I still see a lot of room for improvement, but I think it is good enough and I truly want to share it with everyone. Hence, pay what you want.
