Trying out the Github Command Line

So it's possible and quite convenient to use hardcode git commands to checkout Github repositories. It works fine, once you get the SSH keys sorted out and all that.

I tend to use IntelliJ to checkout new github repositories, as it is soo much easier to point and click.

This always happens to me, when I find myself having to do things I don't do often. Because once you have a repo checked out, that's basically the end of all the complicated stuff and you just get to work.

Checking out using Git

I still prefer using Git to checkout a new repository for now⁴.

The way this works is just do "git clone git@github.com:username/repo.git". You can find this url in the repository on the GitHub website.

However, an ssh key must be available on your GitHub account for the computer/client you're using.

First generate such an ssh key on your computer, using reference [5].

For example: "ssh-keygen -t ed25519 -C "mrbear@mrbear.com"".

Add your ssh key to the ssh-useragent, using "ssh-add ~/.ssh/id_ed25519".

You should see:

$ ssh-add ~/.ssh/id_ed25519
Enter passphrase for /home/mmrbear/.ssh/id_ed25519:
Identity added: /home/mrbear/.ssh/id_ed25519 (mrbear@mrbear.com)

Then you can add the generated key to your Github account using the website, using reference [6].

After that, you can finally just clone your repo as mentioned above.

Installation

GitHub has a command line interface nowadays¹. It's easy to install².

I'm using Fedora, so all it takes on my end is to "sudo dnf install gh".

There used to be a tool called "hub", apparently, which is basically a git wrapper for GitHub. It was an unofficial tool. You can find the differences discusses in [3].

Using the CLI

Logging in using "gh auth login".

$ gh auth login
? Where do you use GitHub? GitHub.com
? What is your preferred protocol for Git operations on this host? SSH
? Upload your SSH public key to your GitHub account? Skip
? How would you like to authenticate GitHub CLI? Login with a web browser

! First copy your one-time code: DFGF-JFDB
Press Enter to open https://github.com/login/device in your browser...
✓ Authentication complete.
- gh config set -h github.com git_protocol ssh
✓ Configured git protocol
✓ Logged in as mrbear

Then the command "gh issue list" shows me open issues.

Works! Quite nice!
