git discard all changes and pull from upstream

Question

How do I fetch upstream repo and make it replace master  I only have one branch on my repo  which is master  and I completely messed it up  so I basically need to start over from the upstream  I think init will do the job  but is there an easier way

There are  at least  two things you can do here ndash you can reclone the remote repo  or you can reset --hard to the common ancestor and then do a pull  which will fast-forward to the latest commit on the remote master   To be concrete  here s a simple extension of Nevik Rehnel s original answer   git reset --hard origin master git pull origin master   NOTE  using git reset --hard will discard any uncommitted changes  and it can be easy to confuse yourself with this command if you re new to git  so make sure you have a sense of what it is going to do before proceeding

git reset  lt hash gt     you need to know the last good hash  so you can remove all your local commits  git fetch upstream git checkout master git merge upstream master git push origin master -f   voila  now your fork is back to same as upstream

You can do it in a single command   git fetch --all  amp  amp  git reset --hard origin master   Or in a pair of commands   git fetch --all git reset --hard origin master   Note than you will lose ALL your local changes

while on branch master  git reset --hard origin master  then do some clean up with git gc  more about this in the man pages   Update  You will also probably need to do a git fetch origin  or git fetch origin master if you only want that branch   it should not matter if you do this before or after the reset   Thanks  eric-walker

I finally realized now that instead of git fetch --all  amp  amp  git reset --hard origin master  it should be git fetch --all  amp  amp  git reset --hard origin  lt branch name gt   instead  if one works on a different branch
