Let's face it, the default terminal you get from macOS is terrible. So I'm writing this little article to show how to improve it with iTerm2, zsh, and some themes.
Installing a better terminal and shell
First, go get iTerm2.
Now, open that bad boy up and make sure it runs any updates. Now you need to install homebrew if you don't already have it.
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Install zsh and zsh-completions
brew install zsh zsh-completions
sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
and Bam! You know have a better shell. But what if i want to make it even better!? This is where themes come in.
Install a theme (Powerlevel 9k)
Step 1) Install the theme
git clone https://github.com/bhilburn/powerlevel9k.git ~/.oh-my-zsh/custom/themes/powerlevel9k
edit your ~/.zshrc file with the following:
Step 2) Install fonts
brew install python sudo easy_install pip pip install --user powerline-status
Step 3) Tell iTerm2 to use the font
In iTerm2 go to the preferences and select Profiles and select Text
In the fonts section, select a desired powerline font. I chose Fira Mono for Powerline and tend to pull the font size up to 14.
