What it does

Shell Samurai is everything I wish I knew about Linux when I started in IT 10 years ago. It's a book that covers the basics of the system along with navigating the command-line quickly. It goes in-depth without being boring or going way too deep.

Build Linux confidence with guided quests on a real hosted training box. Try Chapter 1 free. Full course $30 once, or course and eBook $60.

Practice the commands behind everyday IT work in 18 guided chapters. Connect from your terminal to a Linux box we host, follow each quest, and check your progress as you go. All of Chapter 1 is free. No card needed. Full course: $30 once. No virtual machine to set up. No work server to experiment on. Your hosted practice box gives you a place to try commands and see what they do. Example output. Your commands run over SSH on a real Linux box, separately from this website. Start with files and folders. Build toward checking permissions, inspecting processes, and finding useful clues in logs. Connect, navigate folders, and create, copy, move, and remove files. Read and edit files. Understand…from shellsamurai.com

  • I wrote a modern Command Line Handbook2025 · commandline.stribny.name · ▲454

    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),…

    Hucksh – A shell with a very good memory2023 · ▲93

    In the deep mists of time (circa 2012), I was playing with the Go standard library, and saw how easy it was to stand up a webserver that let you navigate a remote file system, and I thought it was pretty neat. I took a look at my shell history and a frequent pattern of commands was "cd, ls, cd, ls, ...". And I thought "I love my keyboard, but you know, point and click might be nice in this context." And then I thought, "It'd be even cooler if you could run commands there." Skip forward several years, a few earlier implementations, a name change, and now there's Hucksh(ell), a bash-like shell…

  • Pu.sh – a full coding-agent harness in 400 lines of shellApr 2026 · pu.dev · ▲92

    I originally was just messing with pi-autoresearch. Gave it a sample task to build the most portable coding agent. First cut was 6 KB of shell. Great for one-shots, unusable interactively. I was shocked it actually worked. Started building up -- adding features — but with a self-imposed rule: no new dependencies, and sub 500 LOC. This thing had to be truly portable. Just sh, curl, awk. System primitives only. Which means I did some genuinely disgusting things in awk, including JSON parsing and the OpenAI Responses tool loop with reasoning items carried across turns. It's now ~400 lines. In…

    BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT▲688

    I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
