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:
$ %s completion zsh > "${fpath[1]}/_%s"
You will need to start a new shell for this setup to take effect.
Fish:
$ %s completion fish | source
To load completions for each session, execute once:
$ %s completion fish > ~/.config/fish/completions/%s.fish
