Git

Git is version control system for tracking changes in computer files and coordinating work on those files among multiple people. It is primarly used for source-code management in software development, but it can be used to keep track of changes in any set of files.

Git LifeCycle:

1. Working  Directory - 

• The place where your project resides in your local disk.
• This project may or may not be tracked by git.
• In either case, the directory is called the working directory.
• The project can be tracked by git, by using the command git unit.
• By doing git init, it automatically creates a hidden .git folder.

2. Staging Area.

• Once we are in the working directory, we have to specify which files are to be tracked by git.
• We do not specify all files to be tracked in git, because some files could be temporary data which is being generated while execution.
• To add files in the staging area, we use the command git add.

3. Commit.

• Once the files are selected and are ready in the staging area, they can now be saved in repository.
• Saving a file in the repository of git is known as doing a commit.
• When we commit a repository in git, the commit is identified by a commit id.
• The command for initializing this process is git commit-m "message"
