• What approach helped you to best learn Git?
  1 project | /r/AskProgramming | 2 Jul 2023

  For me the Peepcode Git Internals book was a great peek under the hood. I went from "Git has a lot of magical incantations" to "Git is pretty simple and I could probably build a version of it".

• Git as a Beginner

  I generally recommend the Peepcode Git Internals book. The first half explains the internals of how Git works, and the second half is a command reference.

  Once you get the hang of basic Git operations, you should look into how Git works under the hood. Git Internals helped me a lot on this.

The only changed thing is the commit message, and the missing parent in the squash merge. To read more about the underpinnings of git, I can recommend just experimenting with the git command line, and the following resources: - [Building Git by James Coglan](https://shop.jcoglan.com/building-git/) - [Git Internals by Scott Chacon](https://github.com/pluralsight/git-internals-pdf) ## But the history! But Manuel, you say, the history is so much cleaner! To which I counter that it is actually not. If you want to hide the link to the right parent of the non-squash merge (as it is called, the left parent being {% raw %}`main`{% endraw %} ), all you need to do is to hide it. If you use the command-line or a proper tool, use the option to only show first parents. If you only look at the first parent, and configure your git tool to fill in a full log history of the branch into the merge commit message (I personally use the github CLI {% raw %}`gh`{% endraw %} or some git-commit hooks to do it), the squash merge commit is identical to the non squash merge commit. A favorite {% raw %}`git log`{% endraw %} command of mine to quickly look at the history of the main branch, and create a changelog: {% raw %} ```shell > git log --pretty=format:'# %ad %H %s' --date=short --first-parent --reverse # 2022-05-23 02a154bc4f0fa9bca567676d45d136619c076a95 Initial commit # 2022-05-23 16660f8b1d1538ed1b55d8533b3ee7feb68e474c Add more # 2022-05-23 535b740f42e331175f3766c1374116e329a78f7e Merge branch 'work-branch' into no-squash-merge

• How should i go about learning git?
  1 project | /r/learnprogramming | 6 May 2022

  I often recommend the Peepcode Git Internals book. The first half talks about how Git works internally. The second half is a "how to use Git" tutorial. I think understanding the internals (which aren't really that complicated) can really help to demystify Git.

• I was said that I do not know how Git works
  1 project | /r/learnprogramming | 9 Apr 2022

  Conceptually, Git's not really all that complicated. I always recommend people to read the Peepcode Git Internals book (originally $9, now free): https://github.com/pluralsight/git-internals-pdf/blob/master/drafts/peepcode-git.pdf

• would pulling make sense here?
  2 projects | /r/git | 6 Feb 2022

  Check out this page if you haven't yet (alternatively, direct link to the PDF.) I hear it's all good, but the Understanding Git chapter is the one I'd specifically point you to.

• Learn the workings of Git, not just the commands(2021)

  I still very much recommend the Peepcode Git Internals book.
