Linux & the Command Line

Live in the terminal: files, permissions, processes, packages and shell scripting.

Most of the internet runs on Linux, and every serious infrastructure job expects you to be comfortable at a shell prompt.

This course gets you there. No graphical interface, no shortcuts — just the terminal, until it stops being frightening and starts being faster.

Jobs this leads towards

Real roles people do after this course and the ones that follow it.

  • Systems administrator

    Runs the servers that websites and apps live on — most of them Linux.

  • DevOps / platform engineer

    Automates how software is built and deployed; the command line is the workbench.

  • Cybersecurity analyst

    Most security tooling and most attacked servers speak Linux.

Is this for me?

Ninety seconds, no wrong answers, nothing recorded. It tells you how closely this course matches what you enjoy — and where to look if it does not.

What a week looks like

Day to day, so nobody is surprised.

  1. One evening on how it works, one evening building it: cables, switches, routers, Wi-Fi.
  2. You crimp your own cables and test them; a bad crimp is how you learn.
  3. Small networks are built, broken on purpose, and fixed.
  4. A capture-the-flag night near the end, in teams.

Three questions from week one

Get them wrong and you belong here. Get them right and you belong here too. Nothing is recorded.

Books worth having

Between sessions. Ten to twenty minutes; the people who do this are the ones who finish.

  • Habit 3Draw your home network on paper, including the internet side.
