The command "nrm ls" is used to list the available npm registries on your local machine.

In npm (Node Package Manager), a registry is a centralized database of published packages which can be accessed and installed in your project. By default, npm uses the public registry called "https://registry.npmjs.org". However, "nrm ls" allows you to see other available registries that you have configured or that are predefined.

When you execute "nrm ls" in your command-line interface, it will display a list of the registered npm registries. The output typically includes the names of the registries, their corresponding URLs, and an indicator (*) next to the currently active registry.

You can use other nrm commands like "nrm use" to switch between different registries or "nrm add" to add new registries to your configuration. This can be useful when you want to fetch packages from a different registry or use a mirror for faster downloads, among other reasons.
