We all love tab completion in our terminal clients, but case-sensitivity can be a little annoying sometimes. That’s why I opted to enable case-insensitivity instead.

To enable this, add the following to the end of your ~/.zshrc file:

zstyle ':completion:*' matcher-list '' 'm:{a-zA-Z}={A-Za-z}' 'r:|=*' 'l:|=* r:|=*'
autoload -Uz compinit && compinit

Once you’ve added that, restart your terminal. You may be faced with the following:

zsh compinit: insecure directories, run compaudit for list.
Ignore insecure directories and continue [y] or abort compinit [n]?

To fix this, run the following command to change the permissions required to perform this without prompting each time you open your terminal:

sudo chmod -R 755 /usr/local/share/zsh

Now you should be able to tab complete without using the correct case!
