The best open source implementation as of 2020 seems to be: Mozilla rr.
Non-POSIX only here.
Oh but there are usually 2 trees: local and remote.
So you also have to learn how to observe and modify and sync with the remote tree!
But basically:to update the remote tree. And then you can use it exactly like any other branch, except you prefix them with the remote (usually
git fetchorigin/*), e.g.:origin/masteris the latest fetch of the remote version ofmasterorigin/my-featureis the latest fetch of the remote version ofmy-feature
Generate a minimal test repo. You should get in the habit of doing this to test stuff out.
#!/usr/bin/env bash
mkdir git-tips
cd git-tips
git init
for i in 1 2 3 4 5; do
echo $i > f
git add f
git commit -m $i
done
git checkout HEAD~2
git checkout -b my-feature
for i in 6 7; do
echo $i > f
git add f
git commit -m $i
doneSome people like merges, but they are ugly and stupid. Rebase instead and keep linear history.

You may disconnect now if you still like branched history.
But not every directed acyclic graph is a tree.
Example of a tree (and therefore also a DAG):Convention in this presentation: arrows implicitly point up, just like in a

You must:
- be able to visualize the commit tree
- understand how each git command modifies the commit DAG

This was the Holy Grail as of 2023, when text-to-image started to really take off, but text-to-video was miles behind.
