Subject Re: Manual Volume Snapshot retention
Date Thu, 17 Nov 2016 13:40:54 GMT
Hi Dag,
thank you very much, I didn't know jq!
But with your command I get this error:

parse error: Invalid numeric literal at line 1, column 6

I search on Google and I see that it could be a problem of missing double
quote in the json array... but it's strange because it's not a file but an
API query results...
