Git Commands Cheatsheet

GitHub is one of the popular code repositories and also used as a version control tool. Git provides various commands to perform operations like pushing code to a remote repo, pulling code (from somebody else or from the central repo), and many other tasks.

Here we will list out the most commonly used Git commands.

Git Username or Email Setup

//Global setup
git config --global user.name "YourUserName"
git config --global user.email "name@email.com"

//to set the username locally
git config user.name "AnyUserName" 

//to get the user name
git config user.name  //will give you the user name associated currently

//to reset user name and email
git config --global --unset user.name
git config --global --unset user.email
git config --global --unset user.password

Note :

If you are MAC user then you can open KeyChain Access Application from finder and then look for your account listed there. Just click on it and update your password. Now give a try and things will fall in place.

If you are on Windows 10 with Git Remove/update related Credentials stored in Windows Credentials – »Control Panel\All Control Panel Items\Credential Manager

If you are using multiple github accounts, then best option is to use github desktop [available for mac and windows OS], install and clone a repo or browse for an existing repo, this will ask username and password to authenticate separately for each repo.
