This topic covers the information you need to know for the Chrome Shell (CROSH). CROSH and the Google Chrome URL commands
provide some troubleshooting tools, information, and advanced settings.
The Chrome OS does not support Dell BIOS, the F12 boot menu, or DellConnect. Most of the troubleshooting must be done inside the OS.
Chrome Shell (CROSH) and the Chrome URL commands provide some troubleshooting tools, information, and advanced settings. CROSH
is a command line interface similar to the Linux BASH or Windows command (cmd.exe) terminals. Chrome OS is based on Linux, but
CROSH does not recognize most Linux commands. The most useful commands for troubleshooting are memory test, storage_test_1,
storage_test_2, ping, and tracepath. Ping works differently than it does in Windows. By default, it repeats until you press <Ctrl> + <C>,
and it does not show any statistics. The tracepath command is similar to the Windows traceroute command. A detailed explanation of the
commands can be viewed below, by typing help, or help_advanced in CROSH.
1. Open the Chrome browser.
2. Press <Clrl> + <Alt> + <T> The interface appears as shown in the screenshot below:
3. Type in the CROSH command for diagnostics. Type 'help' for a list of available commands. Type help_advanced to display a
complete list of commands for debugging purposes
Alternately, refer to CROSH Commands for the list of the CROSH commands available for diagnostics.

[-c count] [-i interval] [-n] [-s packetsize] [-W waittime] — Sends
ICMP ECHO_REQUEST packets to a network host. If it is "gw",
then the next hop gateway for the default route is used. It works
like the ping command on other operating systems. Press <Clrt> +
<C> to stop the ping process or halt any other command in
CROSH.
[optional args...] — Starts the ssh subsystem if invoked without
any arguments. "ssh <user> <host>", "ssh <user> <host> <port>",
"ssh< user>@<host>". or "ssh <user>@<host> <port>" connect
without entering the subsystem
