Kali linux terminal colors

non color Kali Linux Terminal in root user

I recently install Kali Linux 2020. as you know it’s a non root user by default in this version! and also as you know the terminal it’s colorful for Dir or executable files and etc but when I change my user to root the Terminal is turned to black & white for all thing! do any body have a solution for this?

There’s a good link here that explains what all of that is doing with the PS1 line. It also lists all the colours so you can tailor it to exactly what you’d like

Below is what worked for me, and what produced a colour scheme that I find easy to work with.

As mentioned by others, open up this file from a terminal with

and under the existing ‘# PS1 =’ line (you can delete this line if you wish or leave it commented), add

That gives a decent colour difference to the root and the following directories.

The section responsible for the formatting for this is e[0;31m] the ‘e’ begins a format, the ‘m’ ends it. The ‘0’ here is for normal font, change to 1 for bold, or 4 for underlined. The font colour is the ’31’ (red in this case) — a full list of available colour codes can be found on the above link. All other letters in here are explained in the link also if you’re interested

Then remove the comments (#) from the middle section (under ‘# You may uncomment the following lines if you want ‘ls’ to be colorized’) to show colours on lists

to update the changes which you should now see in the terminal.

I had the same problem, luckily it comes with an easy solution.

If you just want ls to display color, uncommenting some lines in the ~/.bashrc file of the root user will be enough. You’ll find what to do in it; you can access it with vim .bashrc right after logging into root.

If you want to see that characteristic red root@kali:~$ at the beginning of the line too it takes some more steps but it’s also pretty straightforward.

First, launch the terminal as non root and open ~/.bashrc again (this is the non-root user file, the one with the color enabled) and locate the comment that says:

# set a fancy prompt (non-color, unless we know we "want" color) 

Now copy all the code below until you reach:

# enable color support of ls and also add handy aliases 

We don’t need whats below this last line, it is already in root’s .bashrc (the lines we uncommented before).

Now log into root, do vim .bashrc once more and paste the same code somwhere in the file. Relaunch the terminal and it’s done. At least it worked for me.

If you already have a user that has a terminal with colors, you can just copy that users ~/.bashrc to the root home directory and then

while logged in as root, and it should give you the same colors as the user had.

Copy the following code in a text editor in Kali or anywhere and save as .bashrc . Then open the file browser in Kali. In the options, toggle on «hidden files» and then paste the .bashrc file and click on replace and you are done.

Just restart your system once. (I didn’t have to restart, it might work for you, too.) Let me know if it works for you.

How to Change Kali Terminal Prompt Color

The environment variable PS1 (Prompt String One) holds the string that is being displayed as a command or shell prompt in the terminal emulator program Terminal. The prompt string is embedded (interspersed) with color tags in the form of

where x is a display attribute (normal, dim, bold, italics, etc) and y is the color code.

Changing the value or content of PS1 during a terminal session quickly changes the displayed prompt, however, the changes are lost once the terminal session is closed. To make the changes permanent, the hidden file named .bashrc located in the user’s home directory must be edited to reflect the changes in the prompt string.

Displaying the Value of PS1

Command

Output

\ [ \ e ] 0 ; \ u @ \ h : \ w \ a \ ] $ < debian_chroot : + ( $ debian_chroot ) >\ [ \ 033 [ 01 ; 33m \ ] \ u @ \ h \ [ \ 033 [ 00m \ ] : \ [ \ 033 [ 01 ; 34m \ ] \ w \ [ \ 033 [ 00m \ ] \ $

Changing the Prompt

The prompt string can be made as simple as a single character like a dollar sign ($) or a hashtag sign (#). Or it can be any text string you may want. To change the prompt string, assign a new value to PS1.

To enter a string with spaces or non-printable characters, enclose the string with single (‘) or double (“) quotes.

The Default Shell Prompt

The default shell prompt, besides being a cue for entering a shell command in a terminal session, is also used to convey a lot of information about the system. Take for an example the default Kali Linux shell prompt,

The default shell prompt is in red, a warning sign. It indicates that the terminal user has administrative privileges or root privileges. It means that the user may, and can, mess up the system with improper commands like deleting files necessary for Kali’s normal operations.

It also shows the current user root, the host name kali, the current working directory, the home directory represented by the tilde sign (~), and finally, the hashtag sign (#) indicating a priveleged user as opposed to an ordinary user which is usually handed a prompt with a dollar sign ($).

Understanding the Cryptic PS1

To incorporate meaningful information on the shell prompt, bash, the shell interpreter, uses a special set of characters called escape characters , to encode information in the prompt string. See the table (Bash Prompt Escape Characters) below for the complete list of escape characters that are recognized by bash.

Escape Character Code	Meaning
\u	Username
\h	Hostname
\w	Working directory
\$	Display a hashtag if uid=0 (user is root) or else display a dollar sign ($)
