How to run a command that has subcommands?

[OnkelTem]

From the docs:

Commands can also have subcommands, which are added with addSubcommand. A command with subcommands can't run its own code, so run doesn't need to be implemented.

Consider an example:

$ ip route
<prints routes>

$ ip route add ...
<adds a route>

$ ip route del ...
<removes a route>

So I cannot implement a similar CLI with the args package?

Not sure what the question is.

Nothing in your example looks wrong.
What you cannot do it to have

ip

itself do anything but list its subcommands
