Install Zsh and Oh-My-ZSH

Step 1: Installation of Zsh

MacOS High Sierra

If brew is installed

brew install zsh

Else

sudo port install zsh zsh-completions

Ubuntu, Debian & derivatives (Windows 10 WSL | Native Linux kernel with Windows 10 build 1903)

apt install zsh

Centos/RHEL

sudo yum update && sudo yum -y install zsh

Fedora

dnf install zsh

Step 2: Setup Zsh as default shell

To set zsh as your default shell, execute the following for macOS High Sierra

chsh -s /bin/zsh

Step 3: Install Oh-My-Zsh

Getting Started

Prerequisites

• A Unix-like operating system: macOS, Linux, BSD. On Windows: WSL is preferred, but cygwin or msys also mostly work.
• Zsh should be installed (v4.3.9 or more recent). If not pre-installed (run zsh --version to confirm), check the following instructions here: Installing ZSH
• curl or wget should be installed
• git should be installed (recommended v1.7.2 or higher)

Basic Installation

Oh My Zsh is installed by running one of the following commands in your terminal. You can install this via the command-line with either curl or wget.

via curl

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

via wget

sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Manual inspection

It's a good idea to inspect the install script from projects you don't yet know. You can do that by downloading the install script first, looking through it so everything looks normal, then running it:

curl -Lo install.sh https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh
sh install.sh

Step 4: Using Oh My Zsh

Plugins

Oh My Zsh comes with a shitload of plugins to take advantage of. You can take a look in the plugins directory and/or the wiki to see what's currently available.

Enabling Plugins

Once you spot a plugin (or several) that you'd like to use with Oh My Zsh, you'll need to enable them in the .zshrc file. You'll find the zshrc file in your $HOME directory. Open it with your favorite text editor and you'll see a spot to list all the plugins you want to load.

vi ~/.zshrc

For example, this might begin to look like this:

plugins=(
  git
  bundler
  dotenv
  osx
  rake
  rbenv
  ruby
)

Note that the plugins are separated by whitespace. Do not use commas between them.

Using Plugins

Most plugins (should! we're working on this) include a README, which documents how to use them.

Themes

We'll admit it. Early in the Oh My Zsh world, we may have gotten a bit too theme happy. We have over one hundred themes now bundled. Most of them have screenshots on the wiki. Check them out!

Selecting a Theme

Robby's theme is the default one. It's not the fanciest one. It's not the simplest one. It's just the right one (for him).

Once you find a theme that you'd like to use, you will need to edit the ~/.zshrc file. You'll see an environment variable (all caps) in there that looks like:

ZSH_THEME="robbyrussell"

Bonus Plugins and zsh plugin config

Zsh-Autosuggestions

git clone https://github.com/zsh-users/zsh-autosuggestions.git ~/.oh-my-zsh/plugins/zsh-autosuggestions

Zsh-syntax-highlighting

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ~/.oh-my-zsh/plugins/zsh-syntax-highlighting

Once you spot a plugin (or several) that you'd like to use with Oh My Zsh, you'll need to enable them in the .zshrc file. You'll find the zshrc file in your $HOME directory. Open it with your favorite text editor and you'll see a spot to list all the plugins you want to load.

vi ~/.zshrc

For example, this might begin to look like this:

plugins=(
  git
  aws
  docker
  docker-compose
  sudo
  zsh-autosuggestions
  zsh-syntax-highlighting
  zsh-navigation-tools
)

Set a Theme

First we will download the dipadityadas.zsh-theme.

cp dipadityadas.zsh-theme ~/.oh-my-zsh/theme/

After that we will update the ZSH_THEME option in .zshrc file.

ZSH_THEME="dipadityadas"

Lastly, we will execute the zsh again, in order to load our theme.

source ~/.zshrc
