Git is a version control system that allows developers to track and manage changes to their codebase. It allows developers to save different versions of their code, so that they can go back to a previous version if needed. Git also allows for collaboration, as multiple developers can work on the same codebase and use Git to merge their changes together.

Here are some basic Git commands:

• git init: This command is used to initialize a new Git repository. It creates a new .git directory in the current directory, where Git stores all the necessary files and metadata for the repository.

• git status: This command shows the current state of the Git repository, including which files have been modified and which files are staged to be committed.

• git add: This command adds a file to the staging area, which is where files are stored before they are committed to the Git repository. For example, you can use the command git add <file> to add a file to the staging area.

• git commit: This command saves a snapshot of the files in the staging area to the Git repository. When you run this command, you need to include a message that describes the changes you are committing. For example, you can use the command git commit -m "added new feature" to commit the changes with the message "added new feature".

• git branch: This command is used to create, list, or delete branches in a Git repository. Branches allow you to work on multiple versions of the codebase simultaneously. For example, you can use the command git branch <branch-name> to create a new branch.

• git checkout: This command is used to switch between branches in a Git repository. For example, you can use the command git checkout <branch-name> to switch to the specified branch.

• git merge: This command is used to merge changes from one branch into another branch. For example, you can use the command git merge <branch-name> to merge the specified branch into the current branch.

These are just a few of the many Git commands that are available. There are many more commands that you can use to manage and work with your Git repository.
