• Git: On undoing, fixing, or removing commits in git https://sethrobertson.github.io/GitFixUm/fixup.html#discard_all_unpushed

  Removing the last commit
  To remove the last commit from git, you can simply run git reset --hard HEAD^ If you are removing multiple commits from the top, you can run git reset --hard HEAD~2 to remove the last two commits. You can increase the number to remove even more commits.

  If you want to "uncommit" the commits, but keep the changes around for reworking, remove the "--hard": git reset HEAD^ which will evict the commits from the branch and from the index, but leave the working tree around.

  If you want to save the commits on a new branch name, then run git branch newbranchname before doing the git reset.

Git - stash apply vs stash pop

https://stackoverflow.com/questions/15286075/difference-between-git-stash-pop-and-git-stash-apply

git stash pop throws away the (topmost, by default) stash after applying it, whereas git stash apply leaves it in the stash list for possible later reuse (or you can then git stash drop it).<br>
This happens unless there are conflicts after git stash pop, in which case it will not remove the stash, leaving it to behave exactly like git stash apply.<br>
Another way to look at it: git stash pop is git stash apply && git stash drop<br>

Git - update repo content

• Git pull (with rebase)
  git pull --rebase

Git - Submodules

• Git submodules
  

You must run two commands: 
git submodule init 
to initialize your local configuration file, 
and 
git submodule update 
to fetch all the data from that project and check out the appropriate commit listed in your superproject

There is another way to do this which is a little simpler, 
If you pass --recurse-submodules to the git clone command,
it will automatically initialize and update each submodule in the repository,
including nested submodules if any of the submodules in the repository have submodules themselves.

If you already cloned the project and forgot --recurse-submodules,
you can combine the git submodule init and git submodule update steps by running
git submodule update --init.
To also initialize, fetch and checkout any nested submodules, you can use the foolproof
git submodule update --init --recursive.

Update Submodules From upstream

git submodule update --remote,
Git will go into your submodules and fetch and update for you.

Git - Difference between origin master and origin/master

There are actually three things here: origin master is two separate things, and origin/master is one thing.
Three things total.
Two branches:

• master is a local branch
• origin/master is a remote branch (which is a local copy of the branch named "master" on the remote named "origin")

One remote:

• origin is a remote

<< edit files as necessary >>                              # (3)
$ git add ...                                              # (4)
