This one's for the shell ninjas. The ziti CLI comes with auto-complete! You can use completions in any shell supported by Cobra. This post will distill the Cobra instructions with correct examples for ziti in BASH and ZSH.

Install ziti

First, make sure you have the ziti CLI. You can download the latest executable for your OS from GitHub.


Enable Completions in BASH

You must install bash-completion to enable completions for BASH. This is a standard package name for Homebrew, Apt, and Yum/DNF.

Install ziti Completions for BASH

BASH completions are loaded directly into the shell's environment with the source command like this:

source <(ziti completion bash)

That's it! You're done setting up completion in your currently-running BASH shell. Now you can type ziti (followed by a space) and hit the TAB key to auto-complete subcommands and options.

To install this configuration permanently, add the same source command to your BASH configuration file, e.g., ~/.bashrc.

BASH ziti Alias

What if you want to save some typing and say z, instead of ziti, to run a command? Unfortunately, this breaks BASH completion, but it's easily fixed. You must add a completion alias to your BASH config file like this:

alias z=ziti
complete -o default -F __start_ziti z


Enable Completions in ZSH

You must load compinit to enable completion in ZSH. You can run this command to test and then add the same command to your ZSH config, e.g., ~/.zshrcto auto-configure future shells.

autoload -U compinit

Install ziti Completions for ZSH

ZSH completions work with the $fpath environment variable and you must generate the completion script and install it with the correct filename in any one of the directories listed in your $fpath.

# assuming ~/.zsh/completion/ is in $fpath
ziti completion zsh > ~/.zsh/completion/_ziti

ZSH ziti Alias

Good news! Shell aliases work automatically with ZSH completions.

alias z=ziti
# now you can say "z" (space) and tab auto-complete "ziti" commands!

Which shell am I running?

If you didn't change your shell on purpose, you're probably running ZSH on macOS and BASH on Linux (including Windows Subsystem for Linux [WSL]). You can try these two commands to see if the ps command can tell you which shell you're using.

$ ps -p$$ -ocommand=

# try this variant if the first one gave you an error
$ ps -p$$ -ocmd=

With the command chsh, you may change your default shell for all future terminal sessions in macOS or Linux.

# use zsh for future shells 
chsh -s /usr/bin/zsh
