  • cheatsheet.md - Contains common command-line commands, vim commands, and other resources
  • presentation.pptx - Provides a little context

Facilitation

  • 10 min:
    • Provide overview using presentation.pptx
    • Form teams
    • Handout cheatsheet.md and activity.md, one copy per team
  • 30-50 min: Supervise teams as they work through activity.md
  • 5-10 min: Discuss responses to key questions; this can be done along the way

FAQ

Here are some common questions that students may ask.

  1. Why stage? Staging commits gives developers fine-grain control over what to commit. Here are are some references on the subject:

  2. What's the difference between git add . and git add -A .? As of Git 2.0, nothing; they both stage all modifications recursively starting in the current directory.

  3. What is the meaning of HEAD? HEAD refers to the branch or commit currently checked out.

  4. What is the meaning of ^ in HEAD^? "Parent". HEAD^ is the parent of HEAD.

  5. What's the difference between git commit -a and git add . ; git commit? git commit -a will only stage changes in tracked files. git add . adds changes in all files (that are not ignored). So it will add changes in untracked files too.
