Version Control System

What is a version control system?

Version control, also known as “source code control,” is the practice of tracking and managing changes to software code. Version control systems are software tools that help software teams manage changes to source code over time. As development environments accelerate, version control systems help software teams work faster and smarter. They are especially useful for DevOps teams, helping them reduce development time and increase successful deployments.

Benefits of version control systems:

1. A complete long-term change history of all files.
2. Creation of branches and merges.
3. Traceability.
4. Backups.

What is Git?

Git is a free and open source distributed version control system designed to handle everything from small projects to very large projects quickly and efficiently.

Advantages of using Git

1. Distributed
2. Fast
3. Efficient
4. Secure

Disadvantages of using Git

1.  Learning curve.
2.  Number of commands.
3.  Meanings of commands.

Basic Commands:

• Initialize an empty repository in a specific folder.

git init

• Add a specific file.

git add “filename”

• Add all files in the directory.

• Upload the branch “branch_name” to the remote server.

git push origin “branch_name”
