The version control system is a way to manage files/directories to track file changes so that a specific version of files can be tracked later without conflicts.
Git is one of the distributed version control systems that help in:
- Tracking code revision history
- Sharing codebase with collaborator
- Merging collaborators code with your code

Git was created by Linus Torvalds in 2005 using C, Shell, Perl, and Python technologies. He originally called it a ‘stupid content tracker.’
Advantages of Git Over Other Version Control Systems
- Performance: In Git, code changes can be easily committed, compared, and merged. This is because Git is object-based and object formats of Git repository use several combinations of delta encoding to store metadata objects and directory contents.
- Security: Git maintains the integrity of source code. File contents, as well as the relationship between files/directories, are secured via an algorithm which protects the code and code history against accidental damage.
- Flexibility: Git is uniquely designed to support tagging and branching operations and store each activity carried out by the user as an integral part of “change” history.
- Open Source: Git is a widely-used open-source version control with acceptance for more than 10 years. It is a widely-accepted system owing to its universally accepted usability and performance standards.
Disadvantages of Git
- For doing a small operation(s), a lot of commands are needed in Git.
- For Binary files, like images, non-text files, etc., Git becomes slow.
- Bad command-line syntax, which is arbitrary and inconsistent.
- For a beginner, there is a steep learning curve with so many commands and parameters.
Common Git Commands
Init: This command is used to initialize a Git repository from an existing directory of files.
Clone : This command is used to get a copy of the project into your local machine.

Add: This command is used to add files and directories to Git staging areas before you can commit them.
Commit: This command is used to record a snapshot of Git’s staging area.
Reset: This command is used to undo all changes and commits.
Pull: This command is used to fetch files from remote repo and try to merge with your current branch.
Push: This command is used to push new branches and data in the staging area to the remote repo.
Branch: This branch is used to create, manage, and list branches.
Checkout: This command is used to switch from one branch to another branch.
Merge: This command is used to merge a branch into your current branch.
