Git command reference (Launchschool)

CommandDescription

• git status Run this command any time and often to check on the status of the files in the git repository.
• git add This command stages changed files, readying them to be wrapped into the next commit.
• git commit This command commits staged files, wrapping them into a commit. A historical record of commits is what we refer to as a codebase's version or commit history.
• git log View the repository's commit history.
