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