My Terminal Setup with Zsh and Oh My Zsh

My full Zsh configuration for a clean, fast, and productive terminal on macOS. This covers Oh My Zsh, the Pure prompt, version managers, and custom aliases.

Prerequisites

Install the following with Homebrew:

brew install pure zsh-syntax-highlighting zsh-autosuggestions pyenv rbenv

Install Oh My Zsh:

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

Install NVM:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash

Login Shell — .zprofile

The .zprofile runs once per login session and sets up Homebrew, NVM, and rbenv.

eval "$(/opt/homebrew/bin/brew shellenv)"

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm

# Ruby version manager
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

Interactive Shell — .zshrc

The .zshrc runs on every new terminal window.

# Oh My Zsh
export ZSH="$HOME/.oh-my-zsh"
ZSH_THEME=""
zstyle ':omz:update' mode reminder

plugins=(
  git
  brew

)

source $ZSH/oh-my-zsh.sh

# Pure prompt
autoload -U promptinit; promptinit
prompt pure

# Python version manager
export PYENV_ROOT="$HOME/.pyenv"
[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init - zsh)"

# Additional PATH
. "$HOME/.local/bin/env"
export PATH="$HOME/bin:$PATH"

# Aliases
source ~/myaliases.zsh

Plugins

Plugin	What it does
git	Git aliases like gaa, gc, gco, gd, gl, gp
brew	Homebrew completions and aliases
common-aliases	Shortcuts like ll, la, l
z	Jump to frequently used directories by partial name
colored-man-pages	Syntax-highlighted man pages
colorize	Syntax highlighting for file contents
zsh-syntax-highlighting	Highlights commands as you type
zsh-autosuggestions	Suggests commands from history as you type

Theme — Pure

Pure is a minimal and fast Zsh prompt. ZSH_THEME is set to empty because Pure uses Zsh's built-in promptinit system instead of Oh My Zsh's theme engine.

Version Managers

• pyenv — manages Python versions, initialized in .zshrc
• rbenv — manages Ruby versions, initialized in .zprofile
• nvm — manages Node.js versions, initialized in .zprofile

Custom Aliases — myaliases.zsh

The myaliases.zsh file is sourced at the end of .zshrc.

General

alias c='clear'
alias ..='cd ..'
alias ...='cd ../..'
alias h='history'
alias q='exit'
alias o='open .'      # Open current folder in Finder

Network & Ports

po() { lsof -i :"$1" }        # Find what's running on a port: po 3000
kp() { kill $(lsof -t -i:"$1") 2>/dev/null || kill -9 $(lsof -t -i:"$1") }  # Kill process on a port

Process Helpers

alias procs='ps aux | sort -nr -k 3 | head -20'     # Top 20 CPU processes
alias memprocs='ps aux | sort -nr -k 4 | head -20'   # Top 20 memory processes
psg() { ps aux | grep -i "$1" | grep -v grep }        # Search processes

Git

The git plugin provides most aliases. These are the extras:

alias gs='git status'
alias gclean='git branch --merged | grep -v main | xargs git branch -d'

Docker

alias d='docker'
alias dc='docker compose'
alias dcu='docker compose up'
alias dcd='docker compose down'
alias dps='docker ps --format "table {{.Names}}\t{{.Status}}\t{{.Ports}}"'
alias di='docker images'
alias dprune='docker system prune -af'

Node / npm / pnpm

alias nr='npm run'
alias ni='npm install'
alias nis='npm install --save'
alias nid='npm install --save-dev'
alias pr='pnpm run'
alias pi='pnpm install'
alias fixnode='rm -rf node_modules package-lock.json && npm install'

Utilities

alias logf='tail -f'             # Follow a log file
alias big='du -ah . | sort -hr | head -50'   # Top 50 biggest files
alias nads='find . -name "*.DS_Store" -type f -delete'   # Remove .DS_Store files
alias cleanmac='sudo purge'      # Clear macOS memory cache
alias serve='python3 -m http.server 8000'     # Quick HTTP server
alias reload='source ~/.zshrc'   # Reload shell config

Replicate This Setup

1. Install the prerequisites.

2. Download the config files (.zprofile, .zshrc, myaliases.zsh), place them in your home directory, and you're good to go:

   cp .zprofile ~/.zprofile
   cp .zshrc ~/.zshrc
   cp myaliases.zsh ~/myaliases.zsh
   

3. Reload the shell:

   source ~/.zshrc
