Bazaar defines several aliases for locations associated with a branch. These can be used with most commands that expect a location, such as brz push.
The aliases are:
:bound The branch this branch is bound to, for bound branches. :parent The parent of this branch. :public The public location of this branch. :push The saved location used for `brz push` with no arguments. :submit The submit branch for this branch. :this This branch.
For example, to push to the parent location:
brz push :parent
