--graph shows the graph of branches and merges

--decorate adds annotations of branches, such as (master, origin/master)

--all also shows branches that you are not descended from

This comes in pretty colors on the command line

Minimizing work

`git cherry-pick`

Applies the changes of a commit(s) to your branch

-n leaves the changes in your staging area, not making another commits

git cherry-pick -n 2e95
git diff --cached

diff --git a/Futronix.Web.Portal/Views/Home/Index.cshtml b/Futronix.Web.Portal/Views/Home/Index.cshtml
index c6af781..3a8c324 100644

`git revert`

Does the opposite of cherry-pick - it reverses the given commits, leaving the reversal in your commit history. It is much superior to a git reset --hard head^ and a git push --force.

`git rebase`

Moves commits around on mass. Perfect for cherry-picking a large number of commits or moving your commits away from the branch of which you originally branched off.

Abusing remotes to scaffold projects

md rocket-ui-buttons | cd
git init
git remote add scaffold ..\rocket-ui-card-dashboard-system
git fetch scaffold
git cherry-pick ae96
git remove remote scaffold

Small commits lead to reusable commits

When you utilize commits in this way all those arguments about small commits become obsolete. Your commits are a tool - using them in this way will mean you make small commits because you desire, not because you are forced.

Abusing the index with `git update-index` or `git symbolic-ref`

Don't do these unless you have an extremely good reason to and you are really bad-ass!

git update-index can ignore files (without using a git ignore)

git symbolic-ref HEAD refs/heads/myFeatureBranch can switch your branch to myFeatureBranch without checking out any files or resetting the index. This is great for doing sensitive file operations such as removing that 4 gigabyte file someone accidentally committed without having to checkout the file.

`git clean`

Want a clean build? Don't delete and reclone the entire repo - just run git clean -X -d

Staging

`git add -p`

Will allow to stage part of a file. -p is short for --patch

Reset unstaged work

git commit --allow-empty -m 'temp'
git add -A
git reset --hard
git reset --soft head^

Swap unstaged and staged work

git commit --allow-empty -m 'temp'
git add -A
git stash
git reset HEAD^
git stash pop --index

Aliases

are your friends! It is much nicer to type git swap than the above 5 lines! However, only make aliases to save on typing. Don't make them as a substitute for actually learning how git works under the hood. If you don't know what a command does it shouldn't be in your aliases.

To make an alias: git config --global alias.witchhunt "blame -w"

If you are really bad-ass you can put bash in here. I have git alias aliased to view all my aliases:

alias = "!f() { git config --get-regexp ^alias\\. | sed -r -e 's_^alias\\.([^ ]*)_\\1 ........................_; s_^(.{26}[^.]*)\\.*_\\1_' ;}; f"

ch ....................... checkout
co ....................... checkout
st ....................... status
b ........................ branch
cp ....................... cherry-pick
rv ....................... revert --no-edit
df ....................... diff -C
bl ....................... blame -w
lg ....................... log --graph --date=relative --abbrev=4 --color --decorate --pretty=format:'%Cred%h%C(yellow)%d %C(bold blue)%an %Creset%s %Cgreen(%ad)%Creset'
lga ...................... !git lg --all
lg-status ................ !git lg --name-status
last ..................... log -1 --pretty=%s
...

Final note on technique

When moving files, do a commit for the move and then a commit for the edit. Git will track your changes better, particularly when you are editing a significant portion of the file.
