Karaf : bundle:watch

I am a bit confused wrt updates of bundles in Karaf

I tried to do a “bundle:watch *” and “bundle:watch --start” and “bundle:watch -i 1000” but that does not effect whatsoever on bundles being updates.

manually updating bundles works well. What is the process to updates all bundles automatically? I can imagine that this should be done one after the other…

Also, how can we check what is the latest version of a bundle that is available in a repository?
