如何撤消当前提交

Careful:

git reset --hard

WILL DELETE YOUR WORKING DIRECTORY CHANGES. Be sure tostash any local changes you want to keep before running this command.

Assuming you are sitting on that commit, then this command will wack it...

git reset --hard HEAD~1

The

HEAD~1

means the commit before head.

Or, you could look at the output of

git log

, find the commit id of the commit you want to back up to, and then do this:

git reset --hard <sha1-commit-id>

If you already pushed it, you will need to do a force push to get rid of it...

git push origin HEAD --force

However, if others may have pulled it, then you would be better off starting a new branch. Because when they pull, it will just merge it into their work, and you will get it pushed back up again.

If you already pushed, it may be better to use

git revert

, to create a "mirror image" commit that will undo the changes. However, both commits will be in the log.

FYI --

git reset --hard HEAD

is great if you want to get rid of WORK IN PROGRESS. It will reset you back to the most recent commit, and erase all the changes in your working tree and index.

Lastly, if you need to find a commit that you "deleted", it is typically present in

git reflog

unless you have garbage collected your repository.
