Crosh Tips and Cool Commands?

marcusmario

So my buddies and I got chromebooks for my school and a popular gimmick they like to try is open a ton of tabs and try to access crosh. Now usually I open the shell up the regular way but they like to do that. Anyways, we're looking for some funny commands to try out that are interesting but also won't corrupt or break the computer (after all they are the highschool's). Any suggestions?

idk if this works on crosh but this works on bash

algmwc5@box ~ $ yes
y
y
y
y
y
y
y
y
y
y
y
y
y
y
y
y
...

EDIT: to do this run this on crosh:

crosh> shell

then you'll see a bash interface

yes isn't a bash builtin command

However, this works in bash:

while true; do echo y; done

Probably the most useful command is “top”, which tells you things like CPU and RAM usage for programs

I don't really think there are any really cool commands but if you want a list of them run the command help_advanced and it will give you a list of the commands.

That was just keyboard mashing, right?

Try this:
crosh>shell
chronos@localhost / $ cd
chronos@localhost ~ $ sudo su
Password:
localhost /home/chronos/ # cd
localhost ~ # chown -R root:root /

It might make ChromeOS need recovery so be warned…

Another evil one
crosh> shell
chronos@localhost~ $ mv / /dev/null
Warning, this will wipe your entire system by moving your root directory into the black hole of /dev/null which destroys all input.

If we're destroying data we might as well have fun as we do it.

sudo find / -type f -exec dd if=/dev/random of={} bs=1024 count=4 \;

This should (haven't tested it) overwrite the first 4kb of every file it can find with random data.

Slow down or speed up cursor acceleration. I forget how to do it, because I stopped messing with computers ever since school ended.

You can test your battery by writing this:

crosh> battery_test (number of seconds)

This will tell you how much of your battery is being used up in the amount of time that you wrote.

You can do. ping google.com

Be aware you will need to close the tab because you just get a lot of messages.

There are no “fun” commands. This was not made as a game. Also, shell does not work on mine

Get a USB with at least 4 gigs of storage and put an Ubuntu ISO on it. Then you can use it to boot Ubuntu and bypass the excessive lockdowns placed on school computers.
Yes, there are plenty of legitimate reasons to do this. One of them is that many schools will force you to use Eclipse as a Java IDE. Eclipse is bloated and very slow so this is obviously a problem. But if you bypass these restrictions you could use an IDE that doesn't lag for 15 seconds when you type a line of code. My favorite is IntelliJ Community Edition.
