In the working directory, changes are made to files and directories and are then staged in the staging area.

The staging area commits changes to the local repository, forming a fresh snapshot of the project’s current state.

You can push changes from the local repository to the remote one, fostering collaboration and syncing on multiple machines.

Basic Git commands and their functionalities

There are several basic Git commands that every developer should be familiar with:

  1. git init: Initializes a new Git repository in the current directory.

  2. git clone [repository]: Clones a remote repository, creating a local copy on your machine.

  3. git add [file]: Adds a file to the staging area, preparing it for a commit.

  4. git commit -m “[message]”: Commits the changes in the staging area to the local repository.

  5. git status: Shows the current state of the working directory and staging area.

  6. git log: Displays the commit history of the repository, showing the author, date, and commit message.

  7. git push: Pushes the local commits to the remote repository.

  8. git pull: Fetches and merges changes from the remote repository into the current branch.

  9. git branch: Lists all existing branches in the repository.

  10. git checkout [branch]: Switches to the specified branch.

Creating branches and switching between them

Branching allows for the creation of independent lines of development within a repository.

To create a new branch, the command “git branch [branch_name]” can be used.

To switch to a different branch, “git checkout [branch_name]” is used.

Recommend creating distinct branches for various features or bug fixes to simplify management and foster collaboration.

Committing changes and viewing commit history

Committing changes in Git is the process of saving changes to the local repository.

You commit changes by making them, adding to the staging area, and writing a commit message.

You can view the commit history with the “git log” command, displaying commits in reverse chronological order.

Each commit has a unique identifier, author, date, and commit message, allowing for easy tracking of changes.

Managing remote repositories

Git allows for the management of remote repositories hosted on platforms like GitHub or GitLab.

To add a remote repository, the command “git remote add [remote_name] [repository_url]” is used.

Once a remote repository is added, changes can be pushed to it using “git push [remote_name] [branch_name]”.

Fetching changes from the remote repository and merging them into the current branch can be done with “git pull [remote_name] [branch_name]”.

By efficiently managing remote repositories, developers can collaborate and share code seamlessly.

In this section, we have covered the basics of Git, including its workflow, commands, branching, committing changes, and managing remote repositories.

Understanding these concepts is crucial for mastering Git and becoming a proficient developer.
