How to do hg revert --all with git?

Question

When using Mercurial it is possible to issue the following command: hg revert --all --rev <revision> The content of the working directory is set to the specified <revision> but you stay where you are in the tree (same parent, branch, etc).

How to do that in git?
It should behave like git reset --hard <commit> without moving the branch pointer.

TL;DR git config alias.revert-all 'read-tree -um HEAD' git revert-all <commit>

A comparison/test of all variants i found can be found here: http://git.io/vk9it

Answer 1

git read-tree -um @ $thatcommit

will do it. That's "transition the index and worktree from the HEAD aka @ commit to $thatcommit, as for checkout (but without touching HEAD)".

When what you're doing isn't a good match for any of the convenience commands, the core commands have your back :-)

If you need to blow away uncommitted changes, git reset --hard possibly with some selection of git clean options to clear out completely untracked files first, git really hates stomping on uncommitted work without an explicit order.
