ChromeOS Shell (Crosh)
The ChromeOS Shell, also known as Crosh, is a command line interface built into ChromeOS. It is designed for basic system diagnostics and debugging. It is not a full shell and cannot be used to run scripts or install software. Please note, this is different than the ChromeOS Linux Terminal, which offers a full featured Linux Instance with the ability to install software and run scripts.
The commands below may vary slightly depending your ChromeOS device features and enterprise/educational enrollment status.
