How to suppress (or customize) Mac Terminal shell prompt

Question

Currently in my Terminal, every shell prompt looks like ComputerName: FooDir UserName$. The UserName part simply wastes too much space out of my precio

Answer 1

2019 onwards, MacOS default shell is Z Shell. To customize command prompt, add a file named .zshrc in user home and put following line that sets a PS1 environment variable with desired prompt format:

export PS1="[%n]%~> "

Open new terminal

This is result of following format expansion:

• %n User name
• %~ Current directory
