How can I rollback a git repository to a specific commit?

Solution 1:

git reset --hard <old-commit-id>
git push -f <remote-name> <branch-name>

Note: As written in comments below, Using this is dangerous in a collaborative environment: you're rewriting history

Solution 2:

To undo the most recent commit I do this:

First:

git log

get the very latest SHA id to undo.

git revert SHA

That will create a new commit that does the exact opposite of your commit. Then you can push this new commit to bring your app to the state it was before, and your git history will show these changes accordingly.

This is good for an immediate redo of something you just committed, which I find is more often the case for me.

As Mike metioned, you can also do this:

git revert HEAD

Solution 3:

Another way:

Checkout the branch you want to revert, then reset your local working copy back to the commit that you want to be the latest one on the remote server (everything after it will go bye-bye). To do this, in SourceTree, I right-clicked on the and selected "Reset BRANCHNAME to this commit".

Then navigate to your repository's local directory and run this command:

git -c diff.mnemonicprefix=false -c core.quotepath=false push -v -f -- tags REPOSITORY_NAME BRANCHNAME:BRANCHNAME 

This will erase all commits after the current one in your local repository but only for that one branch.
