Git leaves a trail

• When you make a commit, Git prints:

           [your-topic-branch 4e86fa23] Rework foozle subsystem

• If you need to find that commit again, the SHA is in your terminal scrollback

• When you fetch a remote branch, Git prints:

           6e8fab43..bea7535b  dev        -> origin/dev

• Where was origin/dev before the fetch? 6e8fab43

• Where is origin/dev now? bea7535b

• What if you want to look at how it was before?

• 6e8fab43 is still there

        git checkout -b how-it-was-before 6e8fab43

• What if you want to compare them?

        git show 6e8fab43..bea7535b

• Git tries to leave a trail of breadcrumbs in your terminal
