MyOMZ!
MyOMZ is a simple installer for oh-my-zsh (and its common-used plugins), with cross-user(/usr/share) installation and multiple mirrors selection, designed mainly for mainland Chinese users.
Most common Linux distros are supported.
How to use
Download myomz.sh in your way, then execute it as root.
For example, you can directly run this command: sudo sh -c "$(curl -fsSL https://raw.fgit.ml/Lapis-Apple/myomz/master/myomz.sh)"
Or this command, which will download directly from GitHub. sudo sh -c "$(curl -fsSL https://github.com/Lapis-Apple/myomz/raw/main/myomz.sh)"
macOS is currently, sadly, NOT supported.
