The command prompt does exist on a Chromebook.  Not in the sense that it exists as a separate application like on a Windows or Mac computer where it’s known as the terminal.  It doesn’t take much to get to a command prompt on a Chromebook though.

We’ll be telling you just how you can get there.  You may be new to Chromebooks or the Chrome operating system but when you’ve become used to having the option of using the command prompt fret not.  We’ve got your back.

Command Prompt – crosh shell

The command prompt on a Chromebook is accessible from the Google Chrome Browser which comes pre-installed.  Okay so, you’re probably thinking well, how do I get there?  It’s actually quite simple.

Just press ctrl + alt + T and this brings you to what’s called the crosh shell (command prompt or terminal) on a Chromebook.  It’ll now launch in a separate tab of the Chrome browser. Once the crosh shell has launched, you’ll type “shell” to get to the root Linux shell from within your Chrome Browser.

To use the shell, you’ll need to be in developer mode; we also recommend knowing what you’re doing so things don’t go haywire and you don’t break your Chromebook.

To see the basic crosh shell commands available on the Chromebook, you’d type “help” after the crosh command prompt.  When you’re in need of more advanced commands type “help_advanced” instead.  The advanced commands get used for debugging purposes.
