Crosh (short for Chrome Shell) is a built-in command-line interface on Chromebooks that allows users to run network diagnostics, check hardware health, and troubleshoot system issues without needing Developer Mode.
Think of it as the “Terminal” or “Command Prompt” for ChromeOS. While it isn’t a full Linux shell, it is a powerful hidden layer that lets you peek under the hood of your device to fix Wi-Fi, test battery cycles, and verify hardware components.

What Can You Do with Crosh?
Crosh is primarily a diagnostic tool for developers and power users. Here is a breakdown of its core superpowers:
System Diagnostics
- Battery Health: Check cycle counts and discharge rates.
- Hardware Tests: Verify storage (SSD) and memory (RAM) integrity.
- Input Testing: diagnose “ghost touches” on screens or touchpads.
Network Tools
- Connectivity: Use
pingandtracepathto find where the internet is dropping. - Wi-Fi Management: Debug modem settings and packet loss.
- SSH Access: Securely connect to remote servers.
💻 How to Open Crosh
Opening the shell is simple and safe. It does not require Developer Mode.
- Press Ctrl + Alt + T on your keyboard.
- A new browser tab will open. It looks like a blank black screen.

🚫 What Crosh Cannot Do
Crosh is lightweight by design. It is not a full Linux terminal, and it has specific restrictions to keep ChromeOS secure.
No File Management
It is not a file explorer. You cannot move, copy, or browse your local files visually.
No App Installation
You cannot install Android apps or Chrome extensions here. Use the Play Store for that.
No System Config
You cannot change system-wide settings like user accounts or time zones via commands.
No Admin Bypass
Crosh cannot disable enterprise enrollment or remove school restrictions.
Struggling with fleet management? Crosh allows local diagnostics, but it doesn’t give you control over a whole school or business. To manage policies, disable Crosh remotely, or push updates to thousands of devices, you need Google Workspace for Education/Enterprise.
