SubCommands - Command Groups

You read before how to create a program with Commands.

Now we'll see how to create a CLI program with commands that have their own subcommands. Also known as command groups.

For example, the CLI program git has a command remote.

But git remote, in turn, has its own subcommands, like add:

fast →💬 git remote alone shows the current remote repositoriesgit remote
origin

💬 Use -v to make it verbose and show more infogit remote -v
origin  git@github.com:yourusername/typer.git (fetch)
origin  git@github.com:yourusername/typer.git (push)

💬 git remote add takes 2 CLI arguments, a name and URLgit remote add upstream https://github.com/fastapi/typer.git
💬 Doesn't output anything, but now you have another remote repository called upstream
💬 Now check againgit remote -v
origin  git@github.com:yourusername/typer.git (fetch)
origin  git@github.com:yourusername/typer.git (push)
upstream        https://github.com/fastapi/typer.git (fetch)
upstream        https://github.com/fastapi/typer.git (push)
