Transactions are a concept often found in databases. In Mercurial we start a transaction when certain operations are run, such as commit, push, pull...<br> When the operation finishes succesfully, the transaction is marked as complete. If an error occurs, the transaction is "rolled back" and the repository is left in the same state as before.<br> You can manually trigger a rollback with 'hg rollback'. This will undo the last transactional command. If a pull command brought 10 new changesets into the repository on different branches, then '<code>hg rollback</code>' will remove them all. Please note: there is <em>no backup</em> when you rollback a transaction!</p></li> <li><p>'<code>hg strip</code>' will remove a changeset and all its descendants. The changesets are saved as a bundle, which you can apply again if you need them back.</p></li> </ul> </blockquote> <p><a href="https://stackoverflow.com/users/1286571/foreverwintr">ForeverWintr</a> suggests in the comments (in 2016, 5 years later)</p> <blockquote> <p>You can 'un-commit' files by first hg forgetting them, e.g.: <code>hg forget filea; hg commit --amend</code>, but that seems unintuitive.<br> <a href="https://stackoverflow.com/a/19064016/6309"><code>hg strip --keep</code></a> is probably a better solution for modern hg.</p> </blockquote>
