My Productive Terminal Environment with Kitty, Oh My Zsh, and TMUX

For years, I just used whatever default terminal came with my system — I didn’t realize that was like developing on Bloc-notes. Once I discovered Kitty, Oh My Zsh, and Tmux, everything changed.

For starters, if you only run a command or two a day, there’s no need to overthink your terminal; the default one will do just fine. But if you spend a lot of time in it, things can get messy fast. You forget commands, struggle to find something you ran before, or wish you had syntax highlighting like in your code editor. You want smoother navigation, easier session management, and a cleaner workspace without juggling dozens of windows. The list goes on, but you get the idea. So, without any further talk, let’s cut to the chase.

1. Kitty

GPU-Based Terminal Emulator

Kitty is considered a Tier S terminal emulator by many die-hard terminal fans, groupies, or nerds, or whatever you want to call them.

Kitty uses a terminal graphics protocol to render images directly in the terminal.

How to install Kitty?

Official Prebuilt (Recommended) Works on Linux, macOS, Windows (via WSL or native). curl -L https://sw.kovidgoyal.net/kitty/installer.sh | sh /dev/stdin ln -s ~/.local/kitty.app/bin/kitty ~/.local/bin/kitty
Linux Package ManagersUbuntu/Debian: sudo apt install kitty Fedora: sudo dnf install kitty Arch/Manjaro: sudo pacman -S kitty
Note: Package manager versions may not be the latest.
macOSHomebrew: brew install --cask kitty MacPorts: sudo port install kitty
WindowsWSL: Use Linux method inside WSL Native: Download .exe from Kitty website

Once you finish the installation, choose a theme by running kitten theme. You can use / to search for a specific theme, then press Enter, and then select the desired theme.

2. Oh My Zsh

Oh My Zsh is a popular framework for managing your Zsh configuration, offering themes, plugins, and features that make your terminal more powerful and fun to use.

How to install Oh My Zsh?

Run:

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

Or, if you prefer wget, use:

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

Once installed, Oh My Zsh will set Zsh as your default shell and create a ~/.zshrc configuration file.

To enhance your terminal, you can add plugins to your ~/.zshrc file under the plugins=(...) section. Recommended plugins are:

zsh-autosuggestions: suggests commands as you type by displaying faded grey inline predictions based on your command history and common patterns. It significantly speeds up workflow by allowing you to accept suggestions instantly with the right arrow key, reducing typing effort and preventing repetitive command input.
zsh-syntax-highlighting: highlights commands and arguments in real time, giving visual cues about correctness. Valid commands turn green, unknown ones turn red, and flags, strings, paths, and environment variables receive their own colors. This prevents accidental mistakes, typos, and harmful commands before you press Enter.
zsh-completions: adds a massive collection of extra autocompletion rules for tools not covered by default Zsh completions. Pressing Tab becomes far more useful, revealing subcommands, flags, and context-aware arguments that make CLI usage much faster.
autoenv: automatically loads environment-specific settings when entering a directory by reading its .env or .autoenv file. This is ideal for project-based setups such as adjusting PATH values, exporting variables, enabling virtual environments, or preparing development tools. For security, it asks for confirmation on first use to trust each directory’s environment script.

For history search with FZF, add the following to your ~/.zshrc:

source /usr/share/fzf/key-bindings.zsh

Then bind Ctrl + R to fzf-history-widget to interactively search through your command history.

Oh My Zsh comes with many themes. To set one, open ~/.zshrc and change the ZSH_THEME variable, for example:

ZSH_THEME="robbyrussell"

After changing your theme or plugins, reload Zsh to see the changes:

source ~/.zshrc

2. TMUX

TMUX is a terminal multiplexer. It lets you switch easily between several programs in one terminal, detach them (they keep running in the background).
Our goal here is to always use one and only one desktop for your terminal.

How to install TMUX?

On macOS (using Homebrew):

brew install tmux

On Windows (using Windows Subsystem for Linux, WSL):

Open your WSL terminal (Ubuntu recommended)

Run:

sudo apt update && sudo apt install tmux

On Ubuntu / Debian-based Linux / Windows (using Windows Subsystem for Linux, WSL):

Open your WSL terminal (Ubuntu recommended) in Kitty

Run:

sudo apt update && sudo apt install tmux

My TMUX configuration

My initial tmux config was inspired by Typecraft (YouTube channel). After a few tweaks, I ended up with this version. I made sure all the documentation and keybindings are included in the config file; you can check the bindings at the end of it. All you have to do is download tmux.conf and place it in:

~/.config/tmux/

Make sure ~/.tmux/plugins/tpm is empty to avoid any issues when cloning GitHub projects.

Load the configuration and install plugins Run:

tmux source-file ~/.config/tmux/tmux.conf

This may take a while since it will clone the necessary GitHub repositories.

Then start tmux:

tmux

To install plugins: Press Ctrl + s then i To update plugins: Press Ctrl + s then u Your TMUX will look like the figure below — feel free to download the TMUX Quick Tour file
