Git force operations

Git force operations are a set of Git commands that bypass standard safety checks to overwrite history or changes in the repository. These commands are typically used to undo changes, synchronize a local repository with a remote state, or rewrite commit history^[600-developer-tools-git-git-command.md].

Common Force Commands

Local Reset

The git reset --hard command is used to forcefully reset the local repository to a specific state^[600-developer-tools-git-git-command.md].

  • Reset to a specific commit: Running git reset --hard <commit_id> discards all local changes and updates the working directory to match the specified commit^[600-developer-tools-git-git-command.md].
  • Reset to remote state: Using git reset --hard origin/master resets the local branch to match the remote master branch exactly, effectively re-pulling the remote state^[600-developer-tools-git-git-command.md].
  • Undoing merges: If a merge results in conflicts or errors, git reset --hard ORIG_HEAD can be used to abandon the merge attempt and return to the state before it began^[600-developer-tools-git-git-command.md].

Remote Force Push

The git push --force (or git push -f) command forces an update to a remote repository, overwriting its history with the local history^[600-developer-tools-git-git-command.md]. This is often required after local history has been rewritten (e.g., via a rebase or amended commit).

Warning: Force pushing carries significant risk. As noted in source materials, this operation can easily "accidentally overwrite code uploaded by others"^[600-developer-tools-git-git-command.md].
