The fastest way to open Crosh

Crosh (the Chromebook shell) opens with a keyboard shortcut: press Ctrl + Alt + T at the same time. A terminal window appears immediately. That is the standard method on any Chromebook running Chrome OS.

If the keyboard shortcut does not work, your Chromebook may have a different key layout or the feature may be disabled by your administrator. Try the alternative method below.

Key Takeaways

  • Press Ctrl + Alt + T to open Crosh on any standard Chromebook.
  • If the shortcut does not work, open the Files app, press Ctrl + Alt + J to show hidden files, navigate to .ssh, and look for a file named crosh or a shell script.
  • School or work Chromebooks may have Crosh disabled by the administrator, and you cannot re-enable it yourself.
  • Crosh runs Linux commands and lets you troubleshoot network issues, check system information, and run developer tools.
  • Closing the Crosh window does not affect your Chromebook — it is a separate tool, not a system process.

What to do if Ctrl + Alt + T does not work

On some Chromebooks — particularly those issued by schools or workplaces — Crosh may be turned off by the device administrator. You cannot turn it back on yourself. If you own the Chromebook, restart it and try the shortcut again. If it is a managed device, contact your school or IT department to ask whether Crosh access is available.

On older Chromebooks or those with non-standard keyboards, the key combination may differ. Check your device manual or search for your specific model plus "open Crosh" to confirm the correct keys.

Opening Crosh through the Files app

If the keyboard shortcut fails, you can sometimes access a shell through the Files app. Open Files, then press Ctrl + Alt + J to show hidden files and folders. Look for a folder named .ssh or .local. These folders may contain shell scripts or links to Crosh, though this method is less reliable than the keyboard shortcut and does not work on all Chromebooks.

This approach is mainly useful for troubleshooting or on devices where the standard shortcut has been remapped. For most users, the Ctrl + Alt + T shortcut is the only method that works consistently.

What you can do in Crosh

Once Crosh opens, you can run Linux commands to troubleshoot your Chromebook. Common tasks include checking your network connection with ping, viewing system information, testing hardware, and running developer tools. Crosh also lets you access the ssh command to connect to remote servers if your administrator has not blocked it.

Crosh is not the same as a full Linux terminal. It runs a limited set of commands designed for Chrome OS. If you need a full Linux environment, you can enable Linux (Beta) in Chrome OS settings, which provides a separate container with more tools and flexibility.

Closing Crosh and what happens after

Close the Crosh window by clicking the X button in the top right corner or pressing Ctrl + W. Closing it does not affect your Chromebook or any running processes — it simply closes the terminal window. You can open it again at any time with the same keyboard shortcut.

Any commands you ran in Crosh are finished once you close the window. If you were in the middle of a long operation, closing Crosh will stop it. For tasks that take time, let them complete before closing the window.

Crosh on managed Chromebooks

If your Chromebook is managed by a school, workplace, or organization, your administrator may have disabled Crosh entirely. This is common in educational settings to prevent students from accessing system-level tools. There is no way to re-enable it yourself on a managed device.

If you need Crosh access on a managed Chromebook, contact your school or IT support team. They can enable it for your account if your organization's policy allows it. Some organizations enable it only for certain users or roles.

Frequently Asked Questions

Can I use Crosh to install programs on my Chromebook?

Crosh has limited ability to install software. For most applications, you should use the Chrome Web Store or enable Linux (Beta) in settings, which gives you a full Linux container where you can install programs with apt or other package managers. Crosh itself is designed for troubleshooting and system information, not software installation.

Is Crosh the same as a Linux terminal?

No. Crosh is a limited shell built into Chrome OS that runs a subset of Linux commands. It is useful for network troubleshooting and system checks, but it does not have the full range of tools a Linux terminal offers. If you need a complete Linux environment, enable Linux (Beta) in your Chromebook settings.

What if I see a "command not found" error in Crosh?

Crosh does not support all Linux commands. If a command does not work, it may not be available in Crosh. Try a different command or enable Linux (Beta) to access a full terminal. You can also search Chrome OS help for a list of supported Crosh commands.

Can I use Crosh to connect to another computer?

Yes, if your administrator has not blocked it. You can use the ssh command in Crosh to connect to remote servers. Type ssh username@hostname and follow the prompts. Some managed Chromebooks block ssh for security reasons.

Will opening Crosh slow down my Chromebook?

No. Opening Crosh and running basic commands uses very little system resources. Your Chromebook will not slow down noticeably. If you run a resource-intensive command, it may use more CPU or memory, but closing Crosh stops the process immediately.
