git status + git log — Reading the State

Knowing What's Going On

git status is your most-used command. It shows:

• Which branch you're on
• Files changed but not yet staged (red)
• Files staged and ready to commit (green)
• Untracked files (new files Git doesn't know about yet)

git status
# On branch main
# Changes not staged for commit:
#   modified:   app.js
#
# Untracked files:
#   new-file.txt

git log — browsing history

git log                    # full details
git log --oneline          # short: hash + message
git log --oneline --graph  # with branch graph
git log --oneline -5       # last 5 commits only
git show abc1234           # full details of one commit

Your Task

The repo already has two commits. Make a third commit: modify app.txt so it contains v2, then stage and commit it with message "Update app to v2".
