Sensible, slightly opinionated ZSH settings in a single file

Install ZSH on Ubuntu

sudo apt -y install zsh
chsh -s /usr/bin/zsh

Install ZSH on macOS

curl -L git.io/sensible-zshrc > ~/.zshrc
brew install zsh
sudo dscl . -create /Users/$USER UserShell /usr/local/bin/zsh

Use sensible defaults .zshrc

curl -L git.io/sensible-zshrc > ~/.zshrc

Exit your shell and log back in to see the changes.

Features

• ls works with GNU or macOS: groups folders first, uses color and appends a slash for directories
• prompt shows username@server, up to three levels deep from ~ and error code if any
