Git & Github 2021 Cheat Sheet

Git is an open-source, version control tool created in 2005 by developers working on the Linux operating system; GitHub is a company founded in 2008 that makes tools that integrate with git. You do not need GitHub to use git, but you cannot use GitHub without using git.

This cheat sheet features the most important and commonly used Git commands for easy reference.

Installation and Guis

With platform-specific installers for Git, GitHub also provides the ease of staying up-to-date with the latest releases of the command-line tool while providing a graphical user interface for day-to-day interaction, review, and repository synchronization.

GitHub for Windows

GitHub for Mac

For Linux and Solaris platforms

the latest release is available on the official Git website.

Stages and Snapshot

Working with snapshots and the Git staging area

  • diff of what is staged but not yet committed
git commit -m[descriptive message]
Code language: CSS (css)
  • commit your staged content as a new commit snapshot

Branch and Merge

Isolating work in branches, changing context, and integrating changes

git merge [branch]
Code language: CSS (css)
