If you've always wanted to migrate to Linux — or you already use it and want to stop relying on tutorials for every task —, this post is a direct invitation: Gabriel da Silveira Costa, creator of the Toca do Tux channel, offers on Udemy the course “Linux: From migration to operating system administration”, with enrollment always open to new students. It's a course in Portuguese, straight to the point, that takes you by the hand from choosing the distribution all the way to system administration — and serves as a foundation for those aiming at the LPIC-1 and LFCS certifications.

Why I recommend this course
Gabriel is a career systems administrator and a partner here at LinuxPro — and the course reflects that: no rote memorization of standalone commands, but rather the path a sysadmin actually takes in day-to-day work. The numbers on Udemy speak for themselves: rating 4,8 out of 5 (358 reviews), more than 1.000 students enrolled and content updated in November 2025.
There are 29 sections, 72 lessons and 8h07 of video, all in Portuguese, with automatic captions. The approach is to speak the language of those coming from Windows or macOS: each new concept is presented by comparing it with what you already know from the other system, which shortens the learning curve quite a bit.
What you'll learn
- Understand the difference between Linux distributions and which audience each one is aimed at;
- Perform the main Linux operating system administration tasks independently;
- Diagnose and resolve system problems without relying on third parties;
- Understand the operating system in simple and accessible language;
- Build the skill foundation required by certifications LPIC-1 and LFCS.
How the course is organized
The content follows a progressive path — from migration to administration, as the name promises:
- First steps: what Linux distributions are (Debian/Ubuntu, Fedora/Red Hat family, SUSE, Alpine, even Android), installing Debian on a physical or virtual machine, and an introduction to the command terminal;
- Terminal fundamentals: root user and administrator permissions, installing programs (graphically and via package manager), how to get help from the terminal itself, and the first commands;
- Files and directories: Linux directory hierarchy, file identification, everyday commands, permissions and special bits, special characters, operators for combining commands, and keyboard shortcuts;
- System administration: reading and editing text files, command terminals, users and groups, process and service management, compressors and packers;
- Hardware and storage: hardware inspection, drivers and kernel modules, and a robust block of 2 hours solely on partitions and filesystems — the part that trips up certification beginners the most;
- Final stretch: networking, introduction to shell scripting and task scheduling.
There is no formal prerequisite: all you need is a computer (or a virtual machine, or even Windows WSL) and the experience you already have with another operating system, used as a reference during the learning process.
Who the course is for
- Windows users who want to understand Linux — including making the most of WSL (Windows Subsystem for Linux);
- macOS users who are considering migrating, taking advantage of the similarity between the systems;
- Developers (PHP, Python, Lua, C, C++, Rust, .NET…) who need to master the system where the code runs;
- IT professionals who perform Linux administration tasks: installation, networking, storage, and basic security;
- Those targeting certification: the track covers the foundation of the LPIC-1 and LFCS exams.
Who is Gabriel (Toca do Tux)
The Toca do Tux is Gabriel's project to spread Linux in Portuguese: a site with articles and tips at tocadotux.com.br and a YouTube channel at youtube.com/@tocadotux, with videos about distributions, terminal tips, and the day-to-day of those who administer systems. The course is the consolidation of this work into a single, organized track.

Tip from someone who knows the platform: Udemy runs promotions frequently — if the full price feels steep, wait a few days; a discount code almost always shows up.
Conclusion
Linux just turned 35 years old and has never been more present — from Microsoft's servers to Hollywood workstations. Learning to administer it went from a differentiator to a requirement. If you want to take this step with someone who teaches well and in Portuguese, Gabriel's course is the path I recommend. After mastering the basics, keep going here: we have guides like running local AI on Linux with Ollama and the Linux server series for you to apply what you've learned.
Happy studying — and welcome to the burrow! 🐧
