Summarize multiple values with jq reduce

How to use jq's reduce function to handle multiple manipulations?



Given a model like:



{
"usage" : {
"os:linux" : {
"2018_11_18" : {
"amount" : 601046342,
"credits" : 99783
},
"2018_10_18" : {
"amount" : 839785106,
"credits" : 173121
}
}
}
}


And JQ file:



reduce .usage."os:linux" as $item (
{"credits":0,"minutes":0};
."credits" += $item.credits
)


I Get:



{
"credits": 272904,
"minutes": 0
}


Cool, But I want to toal both fields, something like:



reduce .usage."os:linux" as $item (
{"credits":0,"minutes":0};
."credits" += $item.credits,
."minutes" += $item.amount /1000/60
)


Semi-colons cause errors, commas pass, but just handles the last task, i,e,



{
"credits": 0,
"minutes": 24013.85746666667
}

            Or more succintly:



            reduce .usage."os:linux" as $item (
            {};
            .credits += $item.credits
            | .minutes += ($item.amount / 60000) )


            Or ...



            Or abstracting the reduction into the general-purpose utility function sigma/1:



            def sigma(s): reduce s as $s (null; . + $s);

            .usage."os:linux"
            | {credits: sigma(..credits),
            minutes: (sigma(..amount) / 60000) }
