Git local configuration

git config --local user.email "username@email.com"
git config --local user.name "User Name"
git config --local credential.helper ""

 

Checking Your Settings

git config --list

https://git-scm.com/book/en/v2/Getting-Started-About-Version-Control

You can fetch all branches from all remotes like this:

git fetch --all

Create a branch in Git from another branch

git checkout -b feature/YOUR_BRANCH_NAME main

How to delete a Git branch locally

git branch --delete YOUR_BRANCH_NAME

How to “pull” from a local branch into another one?

You have to tell Git from where to pull, in this case from the current directory/repository (.):

git pull . master

But when working locally, you can simply use merge (pull internally calls merge):

git merge master
