Have you ever used Powerline to customize your Terminal? With Oh My Zsh, you’ll not only upgrade your terminal but also enhance its interface in a more appealing and functional way.
This article provides 3 detailed steps to change the interface and customize your Terminal using Oh My Zsh:
Step 1. Install Oh My Zsh
Oh My Zsh is an open-source ZSH configuration management tool, widely developed by the community. It integrates many features, plugins, helpers, and hundreds of useful themes, helping you use the terminal effectively and enjoyably. Currently, Oh My Zsh supports over 275 plugins and over 150 diverse themes.
1. Install Z Shell (Zsh)
Oh My Zsh will use the ZSH shell as its foundation, and it helps customize, extend, and improve the interface and features of the ZSH terminal. Here’s the command to install ZSH:
sudo apt install zsh
2. Download the installation file
You can use curl, wget, or git to do this.
sudo apt install curl sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
After successful installation, Oh My Zsh will automatically set ZSH as the default interface. You can check with the command:
echo $SHELL
In case ZSH is not yet the default, run the following command to set it as default:
chsh -s $(which zsh)
Or
usermod -s $(which zsh) [username]
Step 2. Configure the Terminal Interface
1. List available themes
The folder containing Oh My Zsh themes will be located in the user’s (USER) directory (~/.oh-my-zsh/themes/).
ls /home/$(whoami)/.oh-my-zsh/themes/
Oh My Zsh will initially set the default theme to “robbyrussell”. You can easily change to any theme you want, just modify the ZSH_THEME=”theme-name” parameter in the ~/.zshrc file. (See screenshot)
You can also set the ZSH_THEME=”random” configuration to load random custom themes for your Terminal.
2. Configure theme change
Command to open ~/.zshrc to edit oh my zsh theme configuration:
sudo nano ~/.zshrc
After changing, you need to run this command to apply the configuration.
source ~/.zshrc
Step 3. Install plugins
Oh My Zsh provides many plugins that allow you to add more functionality to the terminal simply by activating them. These plugins are explained in detail in the plugins directory of Oh My Zsh.
You can find many plugins that support interface customization and terminal optimization for Ubuntu. Installing and configuring plugins is very simple. You just need to run the commands below and add the plugin name to the plugin section in the ~/.zshrc file.
