Here we have git and sometimes GitHub basics for an idiot

Git configuration

Configuration can be local or global. We'll discuss global config.

Username

git config --global user.name "Cheshi Mantu"

Email

git config --global user.email cheshi.mantu@emailserver.server

Default code editor

We'll use VS Code.

git config --global core.editor code

Check global config

git config --list

Get your RSA public key

See this article to understand what is it and how to generate the RSA key pair.

Provide keys to GH

1. On GH side click your avatar in the top right corner an then jump to Settings.
2. In the Settings (on the left hand side) find SSH and GPG keys.
3. Click new SSH key
4. Name the key
5. Copy the result of the command cat ~/.ssh/id_rsa.pub.
6. Save.

Start working on a GH project

If all work is done on GH side and there are files, then easy-peasy.

1. Create GH repo (presumably done).
2. Clone the repo.
3. Do stuff.
4. Update GH repo

Clone repo

# I'm using SSH not HTTPS
git clone git@github.com:cheshi-mantu/www-diary.git
# for HTTPS (really?) usage you need different link.
git clone https://github.com/cheshi-mantu/www-diary.git

Do suff, Update GH repo

You need add all the changes, create a new commit and then push the stuff to the cloud (GH).

# collects all the changes
git add .
# creates commit with comment
git commit -m "describe the stuff done"
# pushes the committed changes to GH
git push origin

Relinking git project from one remote to another

Check what is the remote.

git remote -v

It will result in summat like

git remote -v
origin git@github.com:cheshi-mantu/www-diary.git (fetch)
origin git@github.com:cheshi-mantu/www-diary.git (push)

Now, I want to change the remote to gitlab https://gitlab.com/cheshimantu/www-diary.git`

git remote set-url origin git@gitlab.com/cheshimantu/www-diary.git

Then

git remote -v

Then push the stuff to new remote

git push -u origin master
