My zsh setup

Feb 27, 2026 · 2 min read · zsh ·

1. Core Installation

Installed Zsh: The foundation of your new terminal.

1sudo apt update && sudo apt install zsh -y

Installed Oh My Zsh: The framework for themes and plugin management.

1sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

2. Plugin Installation (Download & Enable)

You downloaded the logic for smart suggestions and color-coded commands:

Cloned Autosuggestions:

1git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

Cloned Syntax Highlighting:

1git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting

Enabled in .zshrc: You updated the plugins=(...) line to include both.

1plugins=(git zsh-autosuggestions zsh-syntax-highlighting)

3. Visual Setup (Fonts & Themes)

Downloaded JetBrains Mono Nerd Font: Necessary to render the Agnoster theme symbols properly.

 1# Create the local font directory if it doesn't exist
 2mkdir -p ~/.local/share/fonts
 3
 4# Download the JetBrains Mono Nerd Font (Regular)
 5curl -fLO https://github.com/ryanoasis/nerd-fonts/releases/download/v3.1.1/JetBrainsMono.zip
 6
 7# Unzip it (you might need to install unzip: sudo apt install unzip)
 8unzip JetBrainsMono.zip -d ~/.local/share/fonts
 9
10# Update the system font cache
11fc-cache -fv

Set System Terminal Font: Manually selected the Nerd Font in Terminal Preferences to fix broken Unicode characters.

4. History Migration

Merged Bash History: Copied your old commands into the new Zsh history file so you don't start from zero.

1cat ~/.bash_history >> ~/.zsh_history

Reloaded History: Forced Zsh to recognize the appended lines.

1fc -R ~/.zsh_history

5. Final Configuration

Default Shell: Set Zsh as your primary shell.

1chsh -s $(which zsh)
