• The first pull will be from the parent and will have no updates
• The second pull will be from an alternate repository and will have updates

The bk pull command can be used with or without specifying a BitKeeper URL. Using bk pull without a URL argument pulls from the parent. With a URL, BitKeeper pulls from the repository specified by the URL. By default, the parent is the repository from which the current repository was cloned.

bk pull

It should have told you there was nothing to pull, which is correct; that repository has not changed. Let's go pull from a different repository which does have changes:

bk pull http://bkdemo.bkbits.net/bk_demo1

You now have learned how to get updates from the parent repository or an alternative repository.
