MacOS: Setup for a minimalistic CLI

For macOS users, creating a minimalistic yet powerful CLI environment is easier than you might think. Let’s dive into how you can set up your macOS to become a CLI poweruser.

Why Go Minimalistic?

A minimalistic CLI setup focuses on simplicity, efficiency, and performance. By stripping away unnecessary bloat and optimizing your tools, you can achieve a cleaner, faster, and more intuitive command-line experience. This approach not only enhances productivity but also reduces distractions, allowing you to focus on what’s important.

Key Tools for a Minimalistic CLI Setup

1. Homebrew Homebrew is a must-have for macOS users. It’s a package manager that simplifies the installation of software and tools.

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

With Homebrew installed, you can easily manage and install other CLI tools.

2. iTerm2 iTerm2 is a powerful replacement for the default Terminal app, offering a wealth of features and customization options.

Download and install iTerm2 from iTerm2.com.

3. Zsh and Oh My Zsh Zsh is a powerful shell that offers more features and flexibility than the default bash shell. Oh My Zsh is a framework for managing your Zsh configuration.

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

4. fzf fzf is a command-line fuzzy finder that enhances the way you search and navigate through files.

brew install fzf
$(brew --prefix)/opt/fzf/install

5. tmux tmux is a terminal multiplexer that allows you to manage multiple terminal sessions within a single window.

Essential Configurations

Customize iTerm2

• Profiles: Create custom profiles for different tasks.
• Colors and Fonts: Adjust the color scheme and fonts to your liking.
• Hotkeys: Set up hotkeys for quick access to your profiles and commands.

Configure Zsh and Oh My Zsh

Themes: Choose a minimalistic theme like robbyrussell or agnoster. Plugins: Enable plugins that enhance productivity, such as git, z, and autojump. Edit your ~/.zshrc file to apply changes:

nano ~/.zshrc

Add or adjust the following lines:

ZSH_THEME="agnoster"
plugins=(git z autojump)
source $ZSH/oh-my-zsh.sh

Set Up tmux

Create a .tmux.conf file in your home directory to customize tmux:

nano ~/.tmux.conf

Add these basic configurations to get started:

# Enable mouse mode
set -g mouse on

# Set prefix key to Ctrl-a
unbind C-b
set -g prefix C-a
bind C-a send-prefix

# Split panes using | and -
bind | split-window -h
bind - split-window -v

# Reload tmux configuration
bind r source-file ~/.tmux.conf \; display "Reloaded!"

2. Aliases and Functions Define aliases and functions in your ~/.zshrc to speed up repetitive tasks. For example:

alias ll='ls -lah'

3. Automation Scripts Write and use scripts to automate common tasks, such as setting up your development environment or deploying applications.
