Terminal From Zero

Become fluent at the Linux terminal — the working environment every Linux user lives in. This hands-on, practical course takes you from zero to a real command-line workflow without installing anything locally. Over five weeks you set up a free Linux environment in GitHub Codespaces or a cloud shell, learn the bash, zsh, and sh shells, and master the file-and-directory commands every Linux user types daily. Instructor Alfredo Deza brings over a decade of working with Linux day in and day out — installing servers, building infrastructure, and shipping software on Linux every step of the way. The course focuses on the doing rather than the configuration: every lesson is a recorded screen session you can follow along with, using Linux that is readily available rather than fighting an install. By the end you navigate the filesystem with cd, pwd, ls, and globs; resolve binaries with which and PATH; recall commands with history and tab completion; and copy files and directories with cp. The same skills the rest of the rust-de specialization assumes you already have.
