    Study Notes

    Introduction to Version Control with Git and GitHub

    • Version control systems (VCS) manage and track changes to files, documents, software, and data.
    • VCS track changes, including who made changes, what was changed, why changes were made, and when changes were made.
    • VCS manage changes including add, modify, undo, and redo changes.
    • A traditional approach to version control involves saving different versions to separate files.
    • Git, a popular VCS, uses a single file to store multiple versions.
    • It records changes as metadata, including descriptions, versions, authors, and timestamps.

    Git Commands

    • git add: adds files to the staging area.
    • git commit: saves changes to the local repository.
    • git rm --cached: removes files from staging area.
    • git pull: downloads changes from remote repository.
    • git push: uploads local repository changes to remote repository.
    • git checkout: switches between branches.
    • git reset: resets to a previous commit.
    • git log: displays commit history.

    Initializing a Git Repository

    • Create a directory to hold your project.
    • Navigate to the directory using the cd command.
    • Initialize the local repository using git init.

    Configuring User Name and Email

    • Configure global user settings for Git using git config.
    • Use git config --global user.name "Your Name" and git config --global user.email "[email protected]".

    Adding/Removing Files to/From Staging Area

    • Use git add <file> to add a file to the staging area.
    • Remove a specific file from staging area using git rm --cached <file>.
    • Remove directory from staging area: git rm -r --cache <directory>.

    Git Commit

    • git commit: Saves staged files to the local repository's history, allowing you to add comments.
    • Use $ git commit -m "my comments" to execute commit without opening the editor.

    Git Branch

    • Use branches in Git to manage different versions or features of your project independently.
    • Create a branch using $ git branch newbranch.
    • Switch to a specific branch with $ git checkout newbranch.

    Git Merge

    • Merge changes from a branch back to the primary branch using $ git merge <branch_name>.
    • Resolve merge conflicts by manually editing the files and then adding and committing them.

    Git on GitHub

    • GitHub is a web-based platform for hosting Git repositories.
    • Users can host, collaborate, and share projects.
    • It allows users to create a remote repository.
    • Supports different subscription models with different features.
    • Users can initiate a remote repository using the GitHub website or through command-line commands.

    Sharing GitHub

    • Users can share public repositories with the download button, or by executing the $ git clone (command-line) option.

    Create a GitHub Page

    • Allows hosting of personal, organisation, or project pages from a GitHub repository.
