Question

I have the following JSON

}
]
}
and getting the following values using
cat test.json | jq -r '.apps[].routes[].host, .apps[].state, .apps[].package_updated_at' which produces the following output
nodered-test
NodeRedTestApp
STARTED
STARTED
2018-04-10T17:32:06Z
2018-04-09T21:23:27Z
How can I get the output as
nodered-test STARTED 2018-04-10T17:32:06Z
NodeRedTestApp STARTED 2018-04-09T21:23:27Z
So that I can assign it to a bash script array.

Answer 1

jq solution:
jq -r '.apps[] | [.routes[].host, .state, .package_updated_at] | join(" ")' test.json
The output:
nodered-test STARTED 2018-04-10T17:32:06Z
NodeRedTestApp STARTED 2018-04-09T21:23:27Z
