Who it's for

Engineers who need the shell to stop being a guess.

  • Sysadmins and support engineers moving into DevOps
  • Backend developers moving toward SRE and platform roles
  • Anyone who freezes at a blank terminal prompt

What you'll be able to do

Work on a Linux machine without looking things up.

  • Move around a Linux filesystem and manage files from the shell
  • Read, search and edit text files and logs
  • Combine commands with pipes and redirection
  • Understand users, groups and permissions, and use sudo safely
  • Write and run small bash scripts

The path

9 chapters, from a blank prompt to a working script.

Each lesson is short and ends in a quiz, then a lab on a simulated Ubuntu machine in your browser. Chapter 1 is free. Finish a chapter to open the next.
