git, github-cli

Version control.

Add local project to GitHub

I will utilize the github-cli for this. One must authenticate before being able to use it, but it will pretty much walk you through it automatically if you try to create a new repository without being authenticated.

Say one have a local project foo and wants to add this to GitHub.

Navigate to the root of foo, and do git init -b main. This will initialize the folder as a git repository and set the initial branch to main.

Then do gh repo create projectname and github-cli will take you through the rest.

When that is done, add and commit as usual.

Branching

Say you are on main and wants to create a dev branch.

Creating a branch is done by:

git branch dev

Switching to dev is then done by:

git checkout dev

Or do it all at once:

git checkout -b dev

Generate and add new SSH key

To generate a new SSH key pair, insert your email and execute the following.

ssh-keygen -t ed25519 -C "[email protected]"

When prompted for a location to store the keys, press Enter to save at the default location, ~/.ssh/. Enter a password when prompted as well.

One should now have a id_ed25519 and a id_ed25519.pub within ~/.ssh. Paste the content of the public key, id_ed25519.pub, into GitHub under Settings -> SSH and GPG keys -> New SSH key -> Key field.
