Revert to a commit by a SHA hash in Git?
This question already has an answer here:
如果您想在当前HEAD的顶部提交具有不同提交的确切状态，请撤消所有中间提交，然后可以使用reset创建索引的正确状态以进行提交。
# Reset the index and working tree to the desired tree
# Ensure you have no uncommitted changes that you want to keep
git reset --hard 56e05fced
# Move the branch pointer back to the previous HEAD
git reset --soft HEAD@{1}
git commit -m "Revert to 56e05fced"
What git-revert does is create a commit which undoes changes made in a given commit, creating a commit which is reverse (well, reciprocal) of a given commit. Therefore
git revert <SHA-1>
should and does work.
If you want to rewind back to a specified commit, and you can do this because this part of history was not yet published, you need to use git-reset, not git-revert:
git reset --hard <SHA-1>
(Note that --hard would make you lose any non-committed changes in the working directory).
Additional Notes
By the way, perhaps it is not obvious, but everywhere where documentation says <commit> or <commit-ish> (or <object> ), you can put an SHA-1 identifier (full or shortened) of commit.
It reverts the said commit, that is, adds the commit opposite to it. If you want to checkout an earlier revision, you do:
git checkout 56e05fced214c44a37759efa2dfc25a65d8ae98d
