[Users] cli: how to get value of a parameter

Hello, going through http://www.ovirt.org/wiki/CLI to see some syntax hints. I don't see a way to get parameter of an object. For example if I want to see the size of a vmpool, how can I do it? And is it possible to store values as variables and use then them for further commands? I can run something like this but it seems quite unoptimezed... output redirection to see how many vms are up in a pool: [oVirt shell (connected)]# list vms --kwargs "vmpool-id=eba78b0e-6512-11e1-80c4-5254008e81ee;status-state=up" > /tmp/testfile [oVirt shell (connected)]# shell grep id /tmp/testfile | wc -l 2 shell command to see the size of the pool itself, so can I add more vms to it if the previous : [oVirt shell (connected)]# show vmpool --name mypool id : eba78b0e-6512-11e1-80c4-5254008e81ee name : mypool cluster-id : 99408929-82cf-4dc7-a532-9d998063fa95 size : 2 I would like only the size value and use it then... Thanks in advance, Gianluca
