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. macOS may be supported, any bugs please report.
Download myomz.sh in your way, then execute it as root.
A quick way is to run this command: sudo sh -c "$(curl -fsSL https://github.com/Remik1r3n/myomz/raw/main/myomz.sh)"
