Zsh:
# If shell completion is not already enabled in your environment,
# you will need to enable it. You can execute the following once:
$ echo "autoload -U compinit; compinit" >> ~/.zshrc
# To load completions for each session, execute once:
$ %[1]s completion zsh > "${fpath[1]}/_%[1]s"
You will need to start a new shell for this setup to take effect.
