**ZSH** or the **Z Shell** is another shell like **Bash** and **SH**. It has some advanced usability features that **Bash** and some other shells don’t have. **Git** version control system can be integrated really well with **ZSH** using plugins, which is great for software developers. **ZSH** is much more customizable than **Bash**. **ZSH** has themes and plugins support.

|
||
|
||
In this section, I will show you how to install **Git** and **Oh-My-ZSH** and integrate **Git** with **ZSH** shell. **Git** is not installed by default on Ubuntu 18.04 LTS. But it is available in the official package repository of Ubuntu 18.04 LTS.

|
||
|
||

|
||
|
||
**Oh-My-ZSH** should be installed.
|
||
|
||
Installing **Oh-My-ZSH** changes the **~/.zshrc** configuration file. It means, our **Powerlevel9k** theme and **ZSH Syntax Highlighting** plugin is disabled.
|
||
|

|
||
|
||
Now open a new Terminal and the theme and plugin should be enabled.
|
||
|
||
Now to test whether **Git** integration works, create a new directory and navigate into the directory with the following command:
|
||
|
||
Now initialize a new **Git** repository with the following command:
|
||
|
||
As you can see from the screenshot below, as soon as I initialized a new **Git** repository, the prompt has changed and it shows the **Git** branch that you’re currently in, which is **master**.
|
||
|
||
### Changing Oh-My-ZSH Theme:

|
||
|
||
Now to change the theme, first you have to disable the **Powerlevel9K** theme from the **~/.zshrc** file if you’ve enabled it.
|
||
|
||
Open the **~/.zshrc** file with the following command:

||

||
Now press **<Ctrl>** + **x** and then press **y** and then press **<Enter>** to save the file. Now open up a new terminal, and your theme should be changed.

||
|
||

||
Let’s install the **colored-man-pages** plugin. It adds color to the Linux man pages.
|
||
|
||
First make a note of the name of the plugin.
|
||
|
||
Then edit the **~/.zshrc** file with the following command:
