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/masterresets the local branch to match the remotemasterbranch 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_HEADcan 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].
