====== Ubuntu - GIT - Relative Refs ======

You could use relative refs to move branches around. e.g.,  git branch -f master HEAD~3, etc. 

The "^" Operator goes up to the first parent. 

<code git>
git checkout master^
</code>

----

The "~[integer]" Operator specifies the number of parents you would like to ascend to. 

<code git>
# Goes up 4 parents from HEAD.
git checkout HEAD~4 
</code>
