Googleing this question find all the same answers: use command line in local project to do merge or rebase.
I have simple problem: I forked from a master into my personal github account many months ago but never got around to makeing a local. My repository at github is many commits out of date. It is not obvious how to update. Surely there is a better way than deleteing my existing repository and doing another fork from the master. I would think there is a way at github.com/myaccount to update github/myaccount/reallyoldjunk but looking for help all I see is complicated command line procedures on a local c:\localgitstuff\reallyoldjunk that I dont have.
[EDIT] gave up and deleted my repo and forked a new one. I have a feeling that this is not the normal way to do things in the first place.
