What is -h in "gh config set -h github.com git_protocol ssh"?

Question

This is a command to set the authentication protocol on Github. I'm curious about what the flag means.

Answer 1

From the API docs for gh config set: https://cli.github.com/manual/gh_config_set

Options

-h, --host string   Set per-host setting

It means that key-value setting will only be applied on that particular host (ex. "github.com").
