Crosh -

If you are using ChromeOS Flex (ChromeOS installed on a non-Chromebook, like an old PC), Crosh works largely the same. However, some hardware-specific commands (like battery_test or specific Wi-Fi diagnostics) may behave differently depending on the hardware support of your machine.

Crosh, short for Chrome OS Shell , is a command-line interface (CLI) that acts as a gateway to the underlying Chromium OS kernel. While the average user may never need to open it, Crosh represents the tension between user-friendly design and the deep, granular control that technical users demand.

You do not need to download or install anything. If you are using ChromeOS Flex (ChromeOS installed

This requires putting your Chromebook into Developer Mode . This wipes your local data and lowers the security of your device.

Crosh stands for rome Sh ell. It is a built-in command-line environment similar to the Command Prompt in Windows or Terminal on macOS/Linux. It allows you to run diagnostic tests, debug network issues, and interface with the internal workings of your ChromeOS device. While the average user may never need to

: While Crosh allows for basic diagnostics, it is not a full Linux terminal by default. Most standard Linux commands are "locked down" unless the device is switched into Developer Mode.

: Displays a real-time list of system processes and how much CPU or memory they are consuming, which is helpful if your Chromebook is running slowly.

| Command | Function | | :--- | :--- | | help | Displays the list of basic commands. | | help_advanced | Displays advanced commands. | | ping [url] | Test internet connection. | | top | View CPU and RAM usage. | | memory_test | Test RAM for errors. | | battery_test | Check battery health/discharge rate. | | uptime | Check how long system has been running. | | exit | Close Crosh. | | shell | Switch to Bash shell (Requires Dev Mode). |

By default, Crosh is locked down for security. To unlock the full potential of the command line (including accessing a Bash shell if you have Linux set up), you need to switch to the Developer shell.
