How to edit Custom.css file in Chrome OS?

Question

I have found several interesting articles describing css tweaks to the Chrome OS operating system, but none of them add information how the files are actually editted. I have attempted to open the terminal and use every unix editor i could think of (vi, nano...), but i can't even navigate to the directories specified. Does anyone know how to edit the Custom.css file in the /home/chronos/user/User StyleSheets/ folder? Or any other system file? Can it even be done from within the Os itself? Thanks for your answers.

I am not in the dev or beta channel, if that matters.

Answer 1

I've received the answer from François Beaufort, and i thought it might help other people too.

It's relatively easy to do it actually.
Create your file "Custom.css" in another machine and download it in Downloads.
You just need to access the Shell by typing <Ctrl> <Alt> + t,
Then enter "shell" and press <Enter>,
Type "mv ~/User\ Stylesheets/Custom.css ~/User\ Stylesheets/Custom.css.bak" to save the current one in case and press <Enter>
Then type "cp ~/Downloads/Custom.css ~/User\ Stylesheets/" and press <Enter>

He add's:

you need to activate the developer mode: http://www.chromium.org/chromium-os/developer-information-for-chrome-os-devices/cr-48-chrome-notebook-developer-information#TOC-Entering-Developer-Mode

François, thanks again!

Answer 2

From the article you posted

Locate your Custom.css file in ~/.config/google-chrome/Default/User StyleSheets for Ubuntu or C:\Documents and Settings\\Local Settings\Application Data\Google\Chrome\Default\User StyleSheets for Windows and insert these lines: . . .

So the Custom.css isn't in the appropriate directory?

What happens when you type uname -a in the terminal you're using? If you get something besides 'Bad command or filename', edit your post to include the output of set executed in your terminal.

I'm approaching this from the 'unix' tag point-of-view. Looking at the chomium-OS web page, I don't see any info on a terminal.
