Version Control System

It is for tracking changes in the files. Three types of Version Control Systems

· Local Version Control Systems

· Centralized Version Control Systems

· Distributed Version Control Systems

The local version control system

The local version control system maintains track of files within the local system.

Centralized Version Control Systems

Centralized version control systems contain just one repository and each user gets their own working copy

Distributed Version Control Systems

Distributed version control systems contain multiple repositories. Each user has their own repository and working copy.

git init initialize Local git repo

git add <file> add files to index

git status to get the status of the working tree

git commit to commit changes

git push to push a commit to the remote repository

git pull to pull the latest code from the working repo

git clone to clone the repo to a new directory

To delete the branch in remote

$ git push -d <origin_name> <branch_name>

Example

$ git push -d origin <branch_name

Local

To create new branch

git branch branch-name

$ git switch -c <non_existing_branch>

Commit

To discard all changes

Repository hosting services

Repository hosting services are third-party web applications that wrap and enhance a version control system. You cannot fully utilize a repository hosting service without using an underlying version control system.
