do you mean "how do you figure out what revision a given file version
exists in?" if so, then yes some sort of search command might be useful,
but recognize that a given file version may exist in many revisions.
perhaps the revision that the particular version of the file first
appeared would be the interesting one.

there's really no concept of "which repository a file comes from." if
you and I have version b632c7b9bda8e2df8b392b3606d554398e6ddb97 of some
file, then it is assumed that we have the *same* file. your repository
and my repository are just database files that happen to contain that
revision.

depends a bit on what you mean by identification. 'sha1sum file' gives
you what monotone would use to identify the file, but probably isn't all
that helpful. presumably the revision the file appeared in, along with
the author and date would be more interesting.

hope that helps?
