2. Type the command “sudo sh ~/Downloads/crouton -t xfce” to download and install the “XFCE” desktop environment.
3. Type the command “sudo startxfce4” to start the Linux desktop environment.
4. You can now use the terminal to install Linux applications, such as Python, Node.js, and the Apache web server.
Access the Chrome OS Shell

Accessing the Chrome OS shell allows you to interact with the operating system directly, which can be useful for troubleshooting, automating tasks, and running scripts. Here’s how to access the Chrome OS shell:
1. Press Ctrl + Alt + T to open a terminal window.
2. Type the command “shell” to enter the Chrome OS shell.
3. You can now use shell commands to interact with the operating system, run scripts, and automate tasks.
Run Custom Scripts and Applications

Developer mode allows you to run your own custom scripts and applications on your Chromebook, without the need to use Google’s web-based tools or apps. To run custom scripts and applications, you will need to use the terminal. Here’s how to run a custom script:
1. Create a new file in the “Downloads” folder and give it a name, such as “myscript.sh”.
2. Edit the file and add your script code.
3. Save the file and close the editor.
4. Open a terminal window by pressing Ctrl + Alt + T.
5. Type the command “sudo sh ~/Downloads/myscript.sh” to run the script.
6. Your script will now be executed.
Customize Your Chromebook

Developer mode allows you to customize your Chromebook in ways that are not possible in the standard user mode. For example, you can install custom themes, modify system files, and create your own boot screens. Here are some customization tips:
1. Install a custom theme by downloading it from the Chrome Web Store.
2. Modify system files by using the “vi” or “nano” text editors in the terminal.
3. Create a custom boot screen by replacing the default image with your own.
