Setup & Environment
Before you can practise Linux commands, you need a Linux environment. This chapter covers all the common approaches — from local virtual machines to browser-based cloud terminals.
What You Will Learn
By the end of this chapter you will be able to:
- Install and configure Ubuntu Linux on VirtualBox
- Set up WSL2 (Windows Subsystem for Linux) on Windows 10/11
- Configure your macOS terminal for Linux-compatible workflows
- Use cloud shell environments (no local install required)
- Log in for the first time and understand the shell prompt
Choose Your Setup Method
| Method | OS | Install Effort | Cost | Best For |
|---|---|---|---|---|
| VirtualBox + Ubuntu | Any | Medium | Free | Full Linux desktop experience |
| WSL2 | Windows 10/11 | Low | Free | Windows users, VS Code integration |
| macOS Terminal | macOS | Low | Free | Mac users, similar Unix base |
| AWS CloudShell | Any (browser) | None | Free | Quick practice, no setup |
| Google Cloud Shell | Any (browser) | None | Free (5 GB persistent) | Persistent learning environment |
