git-reset: Reset the repository to a given commit, discarding committed, staged and uncommitted changes since then.
$ git reset --hard ${commit}
try on your machine
The command "git reset --hard ${commit}" is used in Git version control system to reset the current branch to a specific commit and discard any changes made after that commit. Let's break down the command and explain each part:
- "git reset" is a command used to reset the state of the repository.
- "--hard" is an option that tells Git to discard all changes and resets both the staging area (index) and the working directory to match the specified commit.
- "${commit}" is a placeholder that represents the commit hash or reference associated with the desired commit.
Here's what happens when you run this command:
- Git resets the current branch to the commit specified by "${commit}". It means that the branch pointer will point to the specified commit, and the HEAD pointer will also move to that commit.
- The staging area (index) and the working directory are updated to match the state of the specified commit. Any changes you made after that commit will be discarded.
It's crucial to note that using this command can be destructive, as it discards changes permanently. Therefore, it's advised to use it with caution and ensure you have a backup or a proper understanding of the consequences before executing it.
