GitHub Cheat Sheet: Basic Version Control with Git

This cheat sheet provides a quick reference for essential Git commands you'll use for version control on GitHub.

Setup:

  • Install Git: Download and install Git from the official website (https://git-scm.com/downloads)
  • Configure Git: Run git config --global user.name "Your Name" and git config --global user.email "your_email@example.com" to set your username and email for commits.

Working with Repositories:

  • Clone an existing repository: git clone https://github.com/<username>/<repository-name>.git to create a local copy of a remote repository on GitHub.
  • Create a new local repository: git init to initialize a new Git repository in your current directory.

Managing Changes:

  • Track changes: git add <filename> to add a specific file to the staging area (where files are prepared for commit).
  • Track a new folder: git add <foldername> to add all files within a folder to the staging area.
  • Untrack a file: git rm --cached <filename> to remove a file from the staging area (without deleting it from your working directory).
  • See changes: git status to view the status of your working directory and staging area (including modified, staged, and untracked files).
  • See detailed changes: git diff to see the exact changes made to files (between working directory and staging area, or between commits).

Committing Changes:

  • Commit changes: git commit -m "<commit message>" to create a snapshot of your changes with a descriptive message.

Branching and Merging:

  • List branches: git branch to view all local branches.
  • Create a new branch: git branch <branch-name> to create a new branch for development.
  • Switch branches: git checkout <branch-name> to switch to a different branch.
  • Merge branches: git merge <branch-name> to combine changes from another branch into your current branch (use with caution).

Remote Repositories (on GitHub):

  • Add a remote repository: git remote add origin https://github.com/<username>/<repository-name>.git to link your local repository to the remote repository on GitHub (origin is a common alias for the remote).
  • Push changes to remote: git push origin <branch-name> to upload your local commits to the specified branch on the remote repository.
  • Pull updates from remote: git pull origin <branch-name> to download the latest changes from the remote repository and merge them into your local branch.

Additional Tips:

  • Use meaningful commit messages that explain your changes.
  • Regularly push your changes to the remote repository to create a backup and collaborate with others.
  • Leverage Git branching for development and feature work.
  • Explore Git's vast features for more advanced version control tasks.

Remember: This is a basic cheat sheet. Refer to the official Git documentation (https://git-scm.com/doc) for comprehensive details and advanced functionalities.

  To connect to SSH via the Mac Terminal, follow these steps: 1. Open Terminal: You can find it in Applications > Utilities > Terminal, or you can use Spotlight by pressing Command + Space, typing "Terminal," and hitting Enter. 2. Use the ssh command: The basic syntax is ssh username@hostname . For example, if your username is "myuser" and the IP address of the remote server is "123.456.789.0," you would type: ssh myuser@123.456.789.0 If you're connecting using a domain name, you can replace the IP address with the domain. 3. Enter your password: Once you press Enter, Terminal will ask for your password. 4.Type it in (you won't see any characters on the screen as you type for security reasons) and press Enter. And that's it! You should now be connected to the remote server via SSH. Remember to replace "myuser" and "123.456.789.0" with your actual username and the IP address or domain of your SSH server.
