Git revisions cheatsheet

git log master...develop	inspect differences in branches
git rebase -i HEAD~3	rebase last 3 commits
git reset --hard HEAD@{2}	undo last operation that changed HEAD
git checkout v2^{}	checkout the v2 tag (not v2 branch)

The 3rd argument in each of these commands is a gitrevision. These gitrevisions can be passed to many Git commands.

Reference	Description
git show dae68e1	sha1
git show HEAD	reference
git show v1.0.0	tag
git show master	local branch
git show origin/master	remote branch
git show master~2	2 commits back from master
git show master..fix	reachable from fix but not master
git show master...fix	reachable from fix and master, but not both

These are just the common ones, there’s a lot more below! (These work in many other commands, not just git show.)
