That works. Thank you.
Just out of curiosity, from a bash script the following works as expected:
/usr/sbin/vmadm list | /usr/bin/grep myzonealias | /usr/bin/cut -d" " -f1
The following does not work:/usr/sbin/vmadm create -f /opt/json_to_create_vm |
/usr/bin/cut -d" " -f7
I can grep and cut output from “vmadm list” but neither cut or grep works on
“vmadm create -f”.Is the issue that “vmadm create -f” creates additional
processes and writes text to the screen that grep and cut process don’t have
access to?

Rather than parsing the output which shouldn't be considered stable,
you might want to try the approach of performing a lookup after the
zone has been created based on the alias you used.
So, for example, after creating a zone with the 'myzonealias' alias
(catchy I know!):
$ vmadm create <<-EOF
> ..
> "alias": "myzonealias",
> ..
> EOF
You can use 'vmadm lookup' to retrive the UUID:
$ myzoneuuid=$(vmadm lookup -1 alias=myzonealias)
As long as you don't have duplicate aliases (which would probably be a
bad idea in the first place anyway), this should work fine.
