Rollback

Bare-bones basic Mercurial for Subversion users

Have you ever issued a commit command, and then immediately realized you shouldn’t have? Mercurial has a great solution for times like this:

hg rollback

It undoes the last transaction in your repository. Not only does it remove the last commit from the history, but it restores the files in your working tree to their state before that commit. It’s perfect for fixing a bad commit, because you’re put right back where you were before the commit, and can make whatever fix you need before committing again.

I really don’t know how to use these commands yet… so I have created this file for notes as I learn…

Revert and Backout

A simple way to revert a single file to a previous revision, is just to cat the revision and over-write the existing file e.g:
```
hg cat -r 356 btnSave.py > btnSave.py
```
For more advanced ideas, see Difference between Revert and Update in Mercurial.
To back out (revert) the last revision:
```
hg backout tip
```
To revert a changeset which has already been committed, see the backout command in Finding and fixing mistakes
To revert your whole repository to a previous revision: revert back to old version and continue from there
