Tutorial To Make Ubuntu Terminal Look Like Kali Linux

In this Ubuntu Tutorial Post, we will help you to make your Ubuntu terminal look like Kali Linux. Ubuntu is a popular Linux-based operating system and is most preferred by beginners while Kali Linux is popular for security purposes.

Make Ubuntu Terminal Look Like Kali Linux

The first step is to install zsh shell, zshell plugins and some additional tools in your Ubuntu.

Installing ZSH on Ubuntu 22.04 LTS

The Z shell is an interactive shell that incorporates many features like bash, fish, dash, and ksh. Run the following command to install ZSH on Ubuntu-based operating systems.

sudo apt update
sudo apt install zsh

After installation is complete,  run the zsh command to switch from the bash prompt. You will see a z shell configuration prompt where you need to select option zero from the prompt and hit enter.

Now, it’s time to install Z shell plugins.

sudo apt install zsh-syntax-highlighting zsh-autosuggestions

Run the following command to change your default login shell to z shell.

chsh -s /bin/zsh

Modifying the zshrc file

If you want to customize then you need to tweak the zshrc file and which is located in your home directory (~/.zshrc). zshrc is a hidden file so you need to configure your system to see the hidden file. Sometimes the file may not be available, so you must create or delete it if it is already available.

To delete the file run the following command:

rm ~/.zshrc

To create a new file simply run this command:

touch ~/.zshrc

After you have successfully created the .zshrc file, open it with your preferred text editor, copy and paste the following content into your .zshrc file, and save.

# ~/.zshrc file for zsh interactive shells.

# see /usr/share/doc/zsh/examples/zshrc for examples

setopt autocd # change directory just by typing its name

#setopt correct # auto correct mistakes

setopt interactivecomments # allow comments in interactive mode

setopt magicequalsubst # enable filename expansion for arguments of the form ‘anything=expression’

setopt nonomatch # hide error message if there is no match for the pattern

setopt notify # report the status of background jobs immediately

setopt numericglobsort # sort filenames numerically when it makes sense

setopt promptsubst # enable command substitution in prompt


WORDCHARS=${WORDCHARS//\/} # Don't consider certain characters part of the word


# hide EOL sign ('%')

PROMPT_EOL_MARK=""

# configure key keybindings

bindkey -e # emacs key bindings

bindkey ' ' magic-space # do history expansion on space

bindkey '^U' backward-kill-line # ctrl + U

bindkey '^[[3;5~' kill-word # ctrl + Supr

bindkey '^[[1;5C' forward-word # ctrl + ->

bindkey '^[[1;5D' backward-word # ctrl + <-

bindkey '^[[5~' beginning-of-buffer-or-history # page up

bindkey '^[[6~' end-of-buffer-or-history # page down

bindkey '^[[H' beginning-of-line # home

bindkey '^[[F' end-of-line # end

bindkey '^[[Z' undo # shift + tab undo last action

To make the changes take effect, run the following command:

$ source .zshrc
$ . .zshrc

Now, Download color schemes and themes with the following command:

git clone https://github.com/linuxopsys/ubuntu-to-kali-terminal.git
cd ubuntu-to-kali-terminal

Now extract the compressed files:

tar -xvf color-schemes.tar
tar -xvf kali-dark-theme.tar

You will notice a new directory name “usr” in your current working directory.

Now you need to remove the qtermwidget5 directory located in the /usr/share directory and replace it with one from the extracted tar file.

sudo rm -rf /usr/share/qtermwidget5
sudo mv -f usr/share/qtermwidget5 /usr/share

Now its time to Change Qterminal settings

  • Open your Qterminal preferences
  • Change the color scheme to Kali-Dark and then press the Apply button
  • At the bottom of your terminal’s Appearance settings, Adjust the “Application transparency” from “0%” to “5%,”
  • Click apply for the changes to take effect.

Now, it’s time to change the Ubuntu theme. Run the following command to move the Kali-Dark directory from the directory you extracted to /usr/share/themes directory.

sudo mv -f usr/share/themes/Kali-Dark /usr/share/themes

Now, you can tweak your setting by going to the gnome-tweaks by running the following command:

gnome-tweaks

Meanwhile, If you have Gnome Tweak Tool installed in Ubuntu then go through the following article:

Install Gnome Tweak Tool On Ubuntu
