About this course

Get genuinely comfortable on the Linux command line: navigate the filesystem, manage files and permissions, install software, control processes, chain commands with pipes, write tiny shell scripts, and log into real servers with SSH. By the end you'll move confidently in a terminal on Windows (WSL), Mac, or a cloud VM — the exact baseline skill that unlocks backend, cloud, DevOps and cybersecurity roles paid in naira and dollars.

The terminal looks scary — a black window with no buttons. But it's the single skill standing between you and the best-paid jobs in tech. Let's demystify it and get a real Linux terminal open on your machine today.
