I have used GitHub CLI (opens in a new tab) for some time, but I was manually created repos using the web interface on Github.com, and then I was like, "Wait can't I do this quickly on the CLI??".
Yup.
When you're ready to push your local repo to a newly created one on github, you can run the command in the root of the project.
Here's how, you run this command and it has a nice little wizard that it walks you through:
gh repo createThe output looks like
? What would you like to do? Push an existing local repository to GitHub
