Git and Basic Commands

What is Git??

• Git is a version control system for tracking changes in computer files.
• It is developed in 2005 .
• It is distributed version control system. There are other centralised version control systems like SVN.
• It coordinates work between multiple developers.
• We can identify who made what changes and when they are made.
• We can alse revert back changes any time.
• We will have local and remote repositories.

How it works??

• Git will keep track of code history.
• It takes snapshots of our files, snapshots are taken when we commit changes.
• Before committing we need to stage the changes.
• The process goes as follows.   
   Create a local repository. Initialize it as a git repository. Add files and make changes.Stage the files. Commit the changes. Push the changes.

Basic Commands

git init //Inialize local git repository

git add <file> //Add single file to index

git add -A      // Add all files to index

git commit -m "Your message" // commit the changes in index

git push    //push changes to remote repository

git pull  //pull latest from repository

git clone //clone repository into a new directory
