Git - Source control system

Source control is similar to a backup with enabled versioning, which enables you to compare changes to earlier versions and undo changes. Furthermore enables teamwork when working on files with multiple developers.

There are two types of source control.

1. Centralized - SVN is the most popular centralized source control system. It's require connection with central server for all the operations.
2. De-centralized or Distributed - Git is the famous distributed source control system. Since most of the operations are in local, connection with remote server require only for few operations (eg. pull, push)

Git is a distributed/de-centralized source control system, and it's fast since most of the operations are in local.

There are three local stages and one remote stage.

• Working directory
• Staging area (pre-commit holding area)
• Local repository
• Remote repository

Later of Git version 2.28, default branch has changed from master to main.

Github is the most popular git hosting provider.

Git global configurations

git config --global user.name "Ruban B"
git config --global user.email "[e-mail]"
git config --global user.password "GuessMe123"
git config --global init.defaultBranch "main"
git config --global core.editor "notepad++.exe -multilnst -nosession"
git config --global alias.hist "log --all --graph --decorate --oneline"
git config --global diff.tool p4merge
git config --global difftool.p4merge.path "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Perforce"
git config --global difftool.prompt false

git config --global --list
git config --global -e  (it will open the .gitconfig file)
