Install instructions

First, clone the repo with the completion scripts:

git clone https://github.com/capezotte/s6-shell-completion

Bash

Add . "$path_to/s6-shell-completion/bash/s6-rc.bash" the end of your .bashrc.

Zsh

mkdir -p ~/.local/share/zsh/functions
ln -s "$PWD/zsh/"* ~/.local/share/zsh/functions/s6-rc

and restart zsh.

Will it work on distro X?

Tested on a stock Artix s6 configuration, and a Gentoo install with a custom s6 repository.

This scripts goes quite far to ensure it is distribution-agnostic and respects compiled-in distro defaults with as few assumptions as possible.
