[ovirt-users] ovirt-shell : Smart way to run a cmd WHEN another is finished?

Hello, I'd like to night-batch series of actions through some ovirt-shell scripts. Amongst those actions, some are taking a very long time and are treated asynchronously by oVirt. (That may be exports, imports, snapshots, boot, shutdown...) Thus, after having send that long command, I've to find a way to know when to send the next one. I could script a kind of regular status check at determined interval, but I was wondering if there is a smarter way? (because my dumb way would imply for each check a connection. That looks heavy.) Thank you. -- Nicolas ECARNOT
