Show HN: Basics of Bash video course with exercises

My team and I are building a platform for practice-first programming courses. We recently launched the English version, and I made a free course — Basics of Bash.

Topics include:

- Navigation

- FS manipulation

- Redirections and piping

- Files and pagers

- History tips and tricks

- Environment variables

- Aliases

Short videos (~5 min each) + some exercises. Exercise system is the core of our project. We give each user their own container with a browser-based IDE. It's very flexible, and in this particular course we use Ansible to verify students' solutions.

There're also quizzes and lecture notes + additional notes in each lesson.
