# Installing ZSH, Oh-my-Zsh on Ubuntu, MacOS

Oh-My-Zsh is a framework for Zsh, the Z shell.

## 1. Install and set up zsh as default <a href="#heading-1-install-and-set-up-zsh-as-default" id="heading-1-install-and-set-up-zsh-as-default"></a>

The recommended terminal for MacOs is iTerm2. You can download [here](https://iterm2.com/downloads.html)

With Iterm2, your default shell is zsh.&#x20;

### 2. Install oh-my-zsh and Powerline fonts <a href="#heading-2-install-oh-my-zsh-and-powerline-fonts" id="heading-2-install-oh-my-zsh-and-powerline-fonts"></a>

To continue installing software on MacOS **Homebrew** need to be installed. Homebrew is a package manager that allows you to easily install, manage, and update software on macOS.&#x20;

To get started with Homebrew, you can install it using the following command in the terminal:

```
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
```

Once installed, you can use commands like:

* `brew install` to install a package.
* `brew update` to update Homebrew and its package database.
* `brew upgrade` to upgrade all installed packages.
* `brew uninstall` to remove a package.

Homebrew is widely used for managing command-line tools and applications on macOS.

```bash
brew install --cask font-source-code-pro-for-powerline
```

### 3. Install the most useful plugins for zsh <a href="#heading-3-install-the-most-useful-plugins-for-zsh" id="heading-3-install-the-most-useful-plugins-for-zsh"></a>

The most useful plugins for zsh are syntax highlighting and autosuggestions.

```bash
brew install zsh-syntax-highlighting zsh-autosuggestions
```

<figure><img src="/files/s4VnxeAw19sZyw4MO519" alt=""><figcaption></figcaption></figure>

Add the plugin to the list of plugins for Oh My Zsh to load (inside \~/.zshrc):

```bash
nano ~/.zshrc
```

Find the line of enable plugins and add *zsh-autosuggestions* and *zsh-syntax-highlighting*

```bash
plugins=(git zsh-autosuggestions zsh-syntax-highlighting)
```

![](https://cdn.hashnode.com/res/hashnode/image/upload/v1669906107498/ltRpFWeoJ.png?auto=compress,format\&format=webp)

**Ctrl+X** to close nano editor with key **Y** to save changes. After all, reload zsh to enable plugins with command

```bash
source ~/.zshrc
```

If for some reasons, plugins could not install, do it manually by downloading them and putting them in the correct path.

COPY

```c
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
```

```bash
nano ~/.oh-my-zsh/themes/agnoster.zsh-theme
```

Go to the bottom of file and comment out the line "prompt\_context"
