Set up Terminal on Mac 2022

Setting up new Terminal on Mac

  • iTerm2
  • Homebrew
  • Git
  • Zsh (Z Shell) and ohmyzsh
  • ohmyzsh Themes
  • ohmyzsh Plugins
  • iTerms2 Color Schemes

1. iTerm2

Download at iterm2.com/downloads

Set out Status Bar Component Menu
iTerm2 > Preferences > Profiles > Session > Status bar enabled > Configure Status Bar

2. Homebrew

Download at brew.sh
or run this in terminal

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

It will automatically install Developer tools if not available in your system.
When installation is done, run the two commands from the "==> Next steps:" section found in output of your terminal
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/lana/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"

3. Git

Mac already comes with git installed
git --version
=> git version 2.30.1 (Apple Git-130)
Get the latest version of git by installing it with Homebrew

brew install git
Enter fullscreen mode Exit fullscreen mode

git --version
=> git version 2.36.1
Double-check your git global configurations
git config --global --list
If your user.email and user.name are not set, run the following to set your git global configurations
git config --global user.email "<youremail>"
git config --global user.name "<yourname>"

4. zsh and ohmyzsh

zsh

Mac already comes with zsh installed and set as a default
Check what shell is set as a default
echo $SHELL
=> /bin/zsh
If the return is not the above, install zsh with Homebrew

brew install zsh
Enter fullscreen mode Exit fullscreen mode

zsh --version
=> zsh 5.8.1 (x86_64-apple-darwin21.0)
Then Change the default shell in Terminal on Mac or run the following
chsh -s $(which zsh)

ohmyzsh

Install ohmyzsh, the following will run the install script from Github ohmyzsh's install.sh

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