Git branches deleted

Question

I was having three branches master , b1 and b2 . I was working on branch b2 . There was a common folder which was present in all branches. While deleting the folder I selected, delete from other branch also. This option deleted folder as well and other two branches( master and b1 ) from the git server. Anyone know how I can get back master and b1 branch back?

Answer 1

You can use git reflog to find the SHA1 of the last commit of the branch. From that point, you can recreate a branch using

git branch branchName

Answer 2

The git revert command undoes a committed snapshot. But, instead of removing the commit from the project history, it figures out how to undo the changes introduced by the commit and appends a new commit with the resulting content. This prevents Git from losing history, which is important for the integrity of your revision history and for reliable collaboration.

Usage:

git revert <commit>

Generate a new commit that undoes all of the changes introduced in , then apply it to the current branch.
