[SOLVED] Kernel Source: Where is text mode color?

errigour · 05-31-2014, 04:52 AM

Alright i just want to ask if anyone knows where the kernel handles it's color in the source. Like is it possible to add more color options for the linux executable files manually? Also I want to change the orange color \x1B[0;33m to something more yellow and I don't know where to look.

Colorize happens in specific user space programs. The variable LS_COLORS maps file names to colors for the ls command, for example. To modify it, do:

echo LS_COLORS=\"$LS_COLORS\" > ~/.lscolors
echo "source .lscolors" >> ~/.bashrc

Then edit the file .lscolors to add what you want. The format of the string is not well [URL="http://linux-sxs.org/housekeeping/lscolors.html"]documented[/URL, though.

I was looking for more of a permanent change that would affect the color of the tty2 session in the kernel source code.

You will not find that, kernel does not contain such information. (Also there is no "color options for the linux executable") You need to specify your problem much better: what have you done (clicked or which command did you type and execute)? Probably you can post us a screenshot to show which color do you mean.

What do you mean the kernel source code doesn't handle the color? What does then if vmlinux doesn't handle the color? It's the normal yellow color that looks like it's brown.

that is not handled by the kernel itself, but other user space programs. There is no "normal yellow color" in general, but usually it is a default for an application. Which one did you mention? What looks brown now?

Oh ok I get it now thanks. Does anyone know which user space program handles the color? Is it a library file that handles the color? What exactly is an example of a user space program?

color of what? please specify what are you talking about.
All the programs you know about are user space programs, but the kernel itself. So the command ls, grep or a browser, a terminal emulator, text editor or a game all are user space programs and all of them are able to manage its own colors. That's why would be important to explain which one are you talking about.

I think this is what he means

The "Beyond Linux From Scratch" book's Chapter 3 touches on how to set up various color sequences for programs and dialogue in Bash. Check it out and see if it has anything of reference.

Yea Dj Shaji hit it right on the spot.
