Reset local repository branch to be just like remote repository HEAD

Setting your branch to exactly match the remote branch can be done in two steps:

git fetch origingit reset --hard origin/master

If you want to save your current branch's state before doing this (just in case), you can do:

git commit -a -m "Saving my work, just in case"git branch my-saved-work

Now your work is saved on the branch "my-saved-work" in case you decide you want it back (or want to look at it later or diff it against your updated branch).

Note that the first example assumes that the remote repo's name is "origin" and that the branch named "master" in the remote repo matches the currently checked-out branch in your local repo.

BTW, this situation that you're in looks an awful lot like a common case where a push has been done into the currently checked out branch of a non-bare repository. Did you recently push into your local repo? If not, then no worries -- something else must have caused these files to unexpectedly end up modified. Otherwise, you should be aware that it's not recommended to push into a non-bare repository (and not into the currently checked-out branch, in particular).

I needed to do (the solution in the accepted answer):

git fetch origingit reset --hard origin/master

Followed by:

git clean -f

to remove local files

To see what files will be removed (without actually removing them):

git clean -n -f

First, use git reset to reset to the previously fetched HEAD of the corresponding upstream branch:

git reset --hard @{u}

The advantage of specifying @{u} or its verbose form @{upstream} is that the name of the remote repo and branch don't have to be explicitly specified. On Windows or with PowerShell, specify "@{u}" (with double quotes).

Next, as needed, use git clean to remove untracked files, optionally also with -x:

git clean -df

Finally, as needed, get the latest changes:

git pull
