Tutorial - Sharing a Change with another Person
(This page is part of the Tutorial series. Previous part is TutorialShareChange, next part is TutorialMerge)
In TutorialShareChange, we learned how to propagate a changeset from one repository to another. There are other ways of sharing changes between repositories and people, one of the most common is through email.
After we have committed a change, we can export it to a file, and email the file as an attachment to someone else.
To export a change, we use the export command. We must provide a tag, revision number or changeset ID to tell Mercurial what to export. In our case, we want to export the tip. Provided we're still in the my-hello-share directory, let's do just that.

}By default, export just displays the patch, so usually we redirect the output to a file (or use option -o). This file is a patch file in unified diff format, with some extra information that tells Mercurial how to import it.
