I'll assume, from the Bazaar perspective, that this means “revno 123 of
the branch”. Bazaar tracks snapshot revisions of the working tree as a
whole, unlike CVS's per-file tracking.

To get the file at revno 123 in the working tree for the branch (the
most normal place for it to appear):
$ cd bzrbranch/
$ bzr revert --revision 123 HOST/etc/hosts
You could then copy the file to wherever you actually want to use it.
Alternatively, if you really do want something that emits the file
contents to stdout rather than recreating the file:
$ cd bzrbranch/
$ bzr cat --revision 123 HOST/etc/hosts > ~/hosts_HOST_r123
The ‘--revision 123’ option is the verbose spelling of ‘-r 123’.
