Apple has delivered auto-completions for Zsh with the OS, but they seem to not be used…
~/.zshrc with your favourite editor, like nano, and add the following two lines:
autoload -Uz compinit compinit
Now save, exit, close and reopen your terminal.
Now your system utilities should have autocompletion!
Getting more auto-completions
If you’re using [MacPorts] you can install additional completions with:
sudo port install zsh-completions
Now add the following line to
~/.zshrc (above the previous ones we just added):
The end-result should look like this:
fpath=(/opt/local/share/zsh/site-functions $fpath) autoload -Uz compinit compinit
Again, save, close, close and reopen your terminal.
Now you should have auto-completion for additional commands like the port command and more!
Clearing the cache
If you add additional auto-completions, but they don’t work, you might have to clear the cache and rebuild, you can do so with:
rm -f ~/.zcompdump; compinit
That’s all there is to it!
