Interactive Git Cheatsheet (ndpsoftware.com)

I'm not criticizing the cheatsheet and can see how it can help but if I may point out 2 possible points of confusion for Git novices:

If the conceptual boxes of "stash", "workspace",...,"upstream repo" represent a left-to-right timeline of workflow, having "stash" being on the left of "workspace" is somewhat misleading. A stash point-in-time usage can be thought of in the same vertical time-alignment as "index" or "local repository".

If the conceptual boxes represent a storage model, then stash being a separate isolated box is somewhat misleading. The stashes are actually stored in the "local repository". (E.g. an alternative diagram would show "index" and "stash" as nested boxes inside of "local repository".)

I readily admit that spatially rearranging how "stash" is diagrammed complicates the arrows illustrating the git commands. Therefore, maybe the way the cheatsheet did it is the best compromise.


I understand why everyone wants git cheatsheets (there are a lot of commands), but I have yet to see a cheatsheet/etc that does little more than become a crutch.

For better or for worse, git really demands that you learn the concepts and fundamentals. It has a steep learning curve, but it's one that easily pays dividends.

Do I wish it were easier to learn? Of course.

Can you substitute actually learning how git and its workflows are used with cheatsheets and quick primers? Not remotely.

That being said, I think this one is a step in the right direction by being interactive. Something like a "git simulator" could be incredibly powerful in teaching people git.


I could replace "git" and "cheatsheet" with "Unix" and "GUI", or "ed" and "screen editor", or any number of other difficult tasks. Yet even the experts I know today don't use Unix without any GUI -- or line editors.

I've been using git for almost 10 years now, and I've read the "concepts and fundamentals" many times, yet I still find these handy. I still google common git tasks, and take the first StackOverflow hit and paste it in my shell.

Knowing the fundamentals doesn't make it any easier to memorize overly-complex sequences of steps. Or maybe it does, but it requires someone smarter than me, or twice as long as it took to get both my college degrees. At what point do we admit that something is just too complicated?

Reading the Git fundamentals is like learning Maxwell's Equations. Great, you know the fundamentals. That doesn't make it easy to complete any possible task using them. I'm still going to use a cheat sheet (like Ohm's Law!) when I can, rather than deriving everything from fundamentals each time.


I completely agree with you.

I think my original wording came off as more harsh than I intended. I was definitely thinking about cheatsheets solely in the context of handing them off to beginners (I am biased towards this since I end up teaching git to a lot of people as part of my job).

Using cheatsheets as cheatsheets, as you describe, is totally fitting. I just often see them either getting handed to beginners as "here you can learn git real quick with this" or intermediate users relying on them to look up things that they should probably have committed to memory by now (a good example escapes me, unfortunately).


The problem is that git has terrible U/X.

The commands are unintuitive, have defaults that nobody uses, and use names that are prone to misinterpretation because they have completely different meanings from what you'd expect.

It's not only difficult to learn; it's difficult to remember the commands and the switches you have to add every single time (why?), and all the extra commands you have to throw in just to get from a checkout to a complete working tree.

Git's UI really needs an overhaul. Unfortunately, I fear it is already too late.


This is it exactly.

I'm really kind of tired of the "git demands you understand the concepts and the model" excuse because that really isn't what's going on. It's just a poor interface with an un-intuitive set of commands that are organized according to what makes sense to the person who developed the software rather than what makes sense to a person using the software.

Lots of systems demand that you learn the underlying concepts and structures. Indeed, nearly all computer systems demand that when you get to a developer, operations, or admin level. It's actually kind of condescending to keep seeing people repeating that over and over. It's not difficult to understand that git is basically a repository of a repository. If you already understand branching and merging from SVN, it's easy to explain git with a single image[0]. It's still difficult to learn to use git and absolutely nothing about the software eases that transition. Claiming the problem must be with the user and their inability to learn the system should clearly have been incorrect somewhere around 8 years ago when people were still struggling to learn it after it had been out for 5 years.

I imagine some day we'll run into a situation that's similar to apt vs apt-get vs aptitude where there are multiple clients that do the same thing, but it's not clear to me if someone will just create a better product before that time comes along (that product is probably the GitHub client).

> Claiming the problem must be with the user and their inability to learn the system

Please do not put words in my mouth.

I agree that the interface could be a lot better and honestly hope it improves. I do not expect this to happen anytime soon so I work with what I've got.

That being said, the problems git solves in the way that it does so are tricky to wrap your head around. This is why I push people to learn the concepts, not because I think people are stupid for not committing (heh) a bunch of arbitrary commands to memory.

The fact that the interface is so unintuitive is exactly why I like to promote learning the concepts instead of just the commands.

Once you understand the concepts (with or without knowing any of the commands), not only is it sometimes easier to remember the commands, it makes things like cheatsheets useful.

> Indeed, nearly all computer systems demand that when you get to a developer, operations, or admin level. It's actually kind of condescending to keep seeing people repeating that over and over.

Some people, for whatever reason, just don't treat git this way. I've seen plenty of people treat it like they treat tar or some other tool where they just remember a bucket of commands and wonder why nothing ever works.

If it's obvious to you, then I apologize for it sounding condescending, but it's just not obvious to everyone.


Another comparison: iptables with its hard-to-remember syntax, vs ufw.

As UFW is just a wrapper for iptables, I wonder if there's a real possibly of a Git replacement just being a wrapper that simplifies the syntax and maybe some of the conceptual model.


gitflow is just that


> The problem is that git has terrible U/X.

I know this pain. Trying to debug a merge conflict for the first time is like trying to do open heart surgery with no prior training.


Even once you learn git's fundamentals, the UI still sucks though. I like to think I have a pretty good grasp on the git model, but I still consider this article an absolute must for git use: http://gggritso.com/human-git-aliases

Whenever I use a computer and I don't have "git unstage", "git discard", "git publish", etc. it feels like I've lost my opposable thumbs


Here is a git simulator that GitHub consulting uses in their courses. I particularly like the “Free Explore with Remote” mode.

https://git-school.github.io/visualizing-git/


This is close to what I'm wanting. The problem with this is that it doesn't have anywhere near enough supported commands. Even just basic ones like "git add" don't seem to be included.

I think that just makes things even more confusing for absolute beginners, but could be useful for advanced beginners and intermediate git learners.

EDIT: I'm realizing this tool will be perfect for creating instructional materials.


This is actually a good learning tool, and not just a cheatsheet. Understanding how the data moves around the different parts of the git repository is half the battle.


Like I said, I think it's a step in the right direction. It provides a bit more guidance than a typical cheatsheet, but I'd still consider it mainly a cheatsheet.

It doesn't really show how data moves around the different parts as much as it hints that something moves into these nebulous buckets when you run certain commands.


Git gets complex pretty fast, but in teaching the junior devs starting at my company I realized there are really only 5 or so commands that get used on a daily basis for the basic stuff: fetch, checkout, add, commit, push

I think if people new to git can wrap their heads around those, the rest is easier to learn and can be learnt as needed



This is why I now start every git problem-solving session with "Do you want me to fix it or do you want me to help you fix it?"


This cheatsheet has been around for years. Nothing has helped me grok git better than this cheatsheet.

Here is its Github repo: https://github.com/ndp/git-cheatsheet


What really helped me grok git was https://git-man-page-generator.lokaltog.net/ which taught me that the commands and the documentation of git really are pure nonsense, which relieved me from the feeling that I just wasn't seeing the underlying beauty.


I think they've been HN'ed. I'm guessing a stylesheet failed altogether in my browser because it's unreadable.

Am I missing something or is there no `git push`?


Push takes place between your local and remote repo. When you click on either, you'll see remote/local repo commands, including push.


Click on the "Local Repository" column


Ahhhh. I had no idea this thing was interactive. That's not intuitive at all. The only that that indicates that is the "Interaction" in the title and I skipped over that part and just start reading the commands.


Looks like the site is struggling at the moment, cached version here: http://web.archive.org/web/20180914141513/https://ndpsoftwar...


Looks like that is down too now . . .


I only recently started using 'git stash', thanks to this quick script: https://gist.github.com/Ovid/e7ddc56c4710c1baae228b7e4dd3cf7...


nobody has mentioned the other popular cheatsheet called github desktop?


it's missing git fetch and bunch of other stuff


I've mentioned this on another comment. Click on either "Local Repository" or "Upstream Repository" to see the repo-related commands.

Edit: Had "Remote Repository" instead of "Upstream Repository".


git fetch is right there between local and upstream repository.
