I sympathize with wanting to find something that works for his perspective, but I'd recommend just showing him how you work with git, and tell him to explore other tools if he finds the CLI cumbersome.

So in short, I don't teach people to do something differently, I just teach them. I try to be clear that as long as we all are ending up with the same end result, they should feel free to find other ways that work better for them.

I agree with the others saying to just go ahead with teaching him the CLI, however I also think you are overestimating the amount of work required for scoping out a GUI client. Pretty much all of the mainstream clients you could get dropped into and if you understand git, could understand the GUI within about 20 min of poking around.

I actually switched from CLI to a GUI a couple of years ago because I found one that was a pure UI over git (not trying to abstract it) and that had a lot of useful features that were difficult to do from the CLI. If looking for a GUI to check out, I’d really recommend sublime merge, created by the same people as sublime text. You can also see exactly which commands it’s running which makes for an easy transition imo.

With that said, I switched to Sublime Merge purely because of advanced features that were difficult in the CLI. For just learning git, the CLI should be totally fine.

Explain that GIT takes snapshots, kind of like pkZip does, and it FAKES storing deltas. Also explain that GIT stores files by the MD5 hash of their contents, show him the hidden .git folder, explain its structure, and the object folder, with all the subfolders and files Everything else is pointers, and chains of pointers, to those snapshot files, with some labels. --- It took me way too long to grok GIT because I was…

Just point him to the source code to fully grasp the implementation details.

The better your model of how it works, the easier it is to fix things when they fail, no matter the cause.

Knowing that GIT doesn't store deltas explains some of the things that made absolutely no sense before that point.

You don't want to just tell a programmer... oh... here are some magic spells, don't worry about how they work, or how to fix it if you make a mistake.

Tell them you don't expect them to remember all the details. It should only take 10-20 minutes to get them up to speed.

Git through CLI for a new programmer is way more harder than an expert like you getting a feel for GUI. Ultimately the expert needs to learn new ways and tools before expecting novice to learn one. Git is just a tool and not the endgoal itself. VSCode has an excellent extension called Gitlens that provides UI for most basic git operations like branching, checkout remote branches, commit history, revert, stashing. It will take you an hour or so to familiarize with it. Teaching that extension should be sufficient for a new programmer

If it were me, I would suggest gitimmersion to my team mate.

https://git-immersion.github.io/gitimmersion/

If they were my report, I would allocate about twenty paid hours for the training. A contiguous block or fragments of time depending on the way the report trained best…some people want to plow through, others have limits of a few hours at a time.

Not saying gitimmersion is the best tutorial. Only that it is good enough for normal cases

However I am saying that without having been trained as a trainer, outsourcing training is going to be a better use of your time and theirs.

Good luck.

In this situation, I prefer to just present the facts/choice to the other person, much as you have above, and let them decide for themselves:

So, I know you are new to git, and I am happy to help you! Just so you know, I am a bit of a command line kind of guy (because ).

If you'd like to be able to copy exactly what I do and have me help you with any problem that you encounter, you may find it easiest to use exactly the tool/version/environment that I use. However, if you're comfortable doing a bit of research and troubleshooting yourself, feel free to use a different tool that works better for you, and I'll still do my best to help you, but it's possible you'll run into tool-specific issues that I have never encountered and won't be the best person to help with. You could even try both at once, or try one approach and change your mind later on, we'll work it out as we go!

Give him some prescriptive formulas. He can look up the magic incantation for each task he needs to do. Deeper understanding of git can happen gradually. For now he just needs to be able to do a basic workflow. ################################ # download a new project to local disk cd ~/projects git clone someUrl ################################ # get latest code git pull ################################ # observe th…

+1 Prescriptive workflow approach is the best. I am not competent with git, and this is the approach I have taken. I keep note of frequently used commands and solution to frequently encountered problems. I have gone through multiple tutorials from AWS CodeCommit, GitHub, etc but the most helpful has been describing the problem to someone more knowledgeable and have them guide me. Someday git will make sense to me but it is not going to be today or anytime soon.

Telling someone to take a course or go through a tutorial or read a book doesn't help that much, actually it is more discouraging and give impressions of an unhelpful colleague, as a new guy. Depending on GUI or Built-in IDE git features are not the solution, getting to know simple raw native git commands for tasks at hand or problem being faced is the best approach, imo.
