git reset –hard
Syntax
git reset --hard <commit>
Uses of git reset –hard
- Full Reset: Resets the HEAD, staging area, and working directory to match the specified commit.
- Data Loss: Completely discards all changes in the staging area and working directory, making it impossible to recover them through Git.
- Clean State: Useful for discarding unwanted changes and restoring the repository to a known state.
Example
Given a commit history like this:
A -- B -- C (HEAD)
Running the command:
git reset --hard B
The result is:
- HEAD points to commit B.
- Staging area matches commit B.
- Working directory matches commit B.
Use Case
Use –hard when you want to completely discard any changes in the working directory and staging area and revert to a specific commit. This is often used to undo unwanted changes that are no longer needed.
