Synchronise or share .zshrc between accounts
Use a symlink. It uses the ln command in the terminal

ln -s ~/.zshrc /var/root/.zshrc

You can replace /var/root with whatever you need to. This will create a file named .zsrhc in /var/root that is linked to the original copy in your home directory. Please note that you may need sudo before this if you do not have file permissions.
