Git is a distributed version control system that helps track the history of your project's source code and manage changes. Below is a basic explanation of commonly used commands.

• git init

Use this command to initialize a new Git repository. It creates a .git folder in the current directory, which stores the repository's metadata.

• git remote add origin git@bitbucket.org:user/repo-name.git

Sets up a remote repository. In this example, we're specifying a Bitbucket repository URL with the name "origin".

• git add . -A

Adds all modified files in the repository to the staging area to be tracked in the next commit.

• git commit -m "initial commit"

Commits the changes added to the staging area to the repository. The message following this command provides a description of the commit.

• git push -u origin main

Pushes changes from the local repository to the remote repository (origin) on the main branch. The -u option sets main as the default remote branch for future pushes and pulls.

• git status

Displays the current state of the repository. Shows modified files, unstaged changes, branch information, and more.

• git pull

Fetches the latest changes from the remote repository and merges them into your local repository.

• git checkout -b "new-branch"

Creates a new branch (in this example, "new-branch") and switches to it.

• git log

Displays the commit history of the repository. Shows each commit's hash, author, date, and commit message.

• git diff

Shows the differences between the working directory and staging area. This helps you see which files have been modified and what lines have been added or removed.

• git checkout main

Switches branches. In this example, it switches to the main branch.
