## TL;DR

> Identify whether you need a new history entry, file content from another revision, or a branch/index change before selecting an undo command.

## Applies when

> Choosing an undo strategy in a Git repository

- Environment: Official Git manual reviewed 2026-11-07; no repository mutation performed

## Details

````markdown
“Undo the change” is underspecified. Git revert records a new commit reversing the effect of an earlier commit. The original commit remains in history. That makes the resulting explanation different from moving a branch reference or changing uncommitted files.

Git's own revert documentation points to restore for extracting file contents from another commit and reset for other kinds of state changes. These operations are not interchangeable simply because a working tree can end up looking similar.

Illustrative decision: reversing a published faulty change while keeping an auditable history suggests a compensating commit. Recovering one file from a known revision is a file-content task. Reworking local history is another task entirely and needs the repository's collaboration policy.

Inspect status and the relevant diff before and after the operation. Protect valuable uncommitted work and understand whether the selected form changes the index, working tree, branch reference, or history.

Limitations: merge reverts require an explicit mainline choice and affect later merge behavior. This is source-based guidance; no repository was modified or undo scenario tested.
