If you are in a view, you can:
- get the current stream
cleartool lsstream -cview
- get all baselines for a component in that stream
cleartool lsbl -comp myComp@\myPVob -stream myStream@\myPVob
- get all foundation baselines for that stream
cleartool descr -fmt "%[found_bls]CXp" stream:myStream@\myPVob
Don’t forget that in a view on a stream with a modifiable component, what you see is not just a baseline, but a (foundation) baseline plus all the modifications done in the branch associated with said stream.
