Every server, container, and cloud VM runs Linux. This course teaches the terminal from first principles — file system navigation, file operations, permissions, process management, and shell scripting that automates everything you currently do by hand.
This is a text-first course that links out to the best supporting material on the internet instead of trying to replace it. The goal is to make this the best course on linux and the command line you can find — even without producing a single minute of custom video.
This course is built by people who ship production linux systems for a living. It reflects how things actually work on real projects — not how the documentation describes them.
Every day has working code snippets you can paste into your editor and run right now. The emphasis is on understanding what each line does, not memorizing syntax.
Instead of shooting videos that go stale in six months, Precision AI Academy links to the definitive open-source implementations, official documentation, and the best conference talks on the topic.
Each day is designed to finish in about an hour of focused reading plus hands-on work. You can do the whole course over a week of lunch breaks. No calendar commitment, no live classes, no quizzes.
Each day stands alone. Read them in order for the full picture, or jump straight to the day that answers the question you have today.
The shell, absolute vs relative paths, ls/cd/pwd/mkdir/rm, the FHS (Filesystem Hierarchy Standard), and why everything in Linux is a file.
cat, less, head, tail, grep, find, and ripgrep for searching content. Pipes and redirects for composing commands. sed and awk for text transformation.
Read/write/execute bits, chmod numeric and symbolic notation, chown, sudo, and the principle of least privilege applied to file and directory access.
ps, top, htop, kill, nice, background vs foreground jobs, systemd basics, and the diagnostic commands that identify what’s consuming CPU and memory.
Variables, if/else, loops, functions, command substitution, and exit codes. Writing scripts that automate backup, deployment, and monitoring tasks.
Instead of shooting our own videos, Precision AI Academy links to the best deep-dives already on YouTube. Watch them alongside the course. All external, all free, all from builders who ship this stuff.
From first terminal session to shell scripting. The most comprehensive beginner Linux course.
chmod, chown, and the permission model that controls every file on a Linux system.
Variables, conditionals, loops, functions, and the scripting patterns used in real automation scripts.
ps, kill, nice, background jobs, and using htop to diagnose CPU and memory issues.
The best way to understand any technology is to read the production-grade implementations that prove it works. These repositories implement patterns from every day of this course.
The fastest file content search tool — covered in Day 2. The SIMD-accelerated regex engine source explains why it outperforms grep.
A faster, more user-friendly find replacement. Used alongside ripgrep in Day 2 for combined search workflows.
Terminal multiplexer — multiple terminal sessions in one window. Essential for server work after this course.
Curated list of shell tools, plugins, and frameworks. The reference for finding the right CLI tool after this course.
You click through GUIs and copy-paste commands without understanding them. This course fixes that and makes the terminal the fastest tool you have.
You develop on Windows but deploy to Linux. This course teaches the Linux mental model that makes server-side debugging stop being mysterious.
CS courses assume Linux comfort. This course builds the terminal fluency that makes everything from git to compilers easier.
