Can you not enter multiple bundle id's in the command?
osgi:update 123 124 125
Or it could be that multiple ids is not yet support. I can't recall.
I tried multiple IDs but it said "too many parameters"
What version are you using? osgi:info or just info should display version details about SMX / Karaf etc.
Also, is there a way to update bundles based on a regex pattern for the name?
For example, if all my bundle names are displayed as "HelloWorld" is there a way to update based on the name?
