Julia Evans' Git cheat sheet (programming.dev)

Git cheat sheets are a dime-a-dozen but I think this one is awfully concise for its scope.

  • Visually covers branching (WITH the commands -- rebasing the current branch can be confusing for the unfamiliar)
  • Covers reflog
  • Literally almost identical to how I use git (most sheets are either Too Much or Too Little)

Click to view diffs is super ergonomic; on the other hand, I actually have a story about the Git CLI trumping the GUI (spoiler: reflog).

In high school we had gotten the funding to build a robot, and one of the adults in charge -- guy was brilliant -- was using GitHub Desktop to conduct a feature merge with the student who served as team lead. The thing was, he was used to older codebases, so all of his experience was with CVS instead of Git -- so when the two slightly messed up the git merge, they discussed recloning everything instead of wasting time plumbing the error (relevant xkcd).

That was one of the earliest times I had the cajones to walk up to a superior and say "No, you're doing this totally wrong. You don't have to do that."

He looked at me and nodded. "What would you do instead?"

"Reflog."

"Reflog? I've never heard of it before. Can you show us?"

I hopped onto the laptop and clicked around GitHub Desktop, but couldn't manage to find any buttons related to reflog... so I went straight to cmd.exe instead.

git reflog
git reset --hard "HEAD@{7}"

"Done. We can continue rebasing."

And after that, the advisor complimented me for using the command line tool!

"Lots of GUI apps are just limited frontends to the real meat and potatoes, the command line. Nice job!"

I felt like a wizard! And so I became the team's Git-inator.
