如何使用 jq 在 json 中的数组中 select 多个值

Question

Am using jq to get multiple responses from the JSON file using the below command.

.components| to_entries[]| "\(.key)- \(.value.status)"

which gives me below

Server2- UP

server1 - UP

Splunk- UP

Datameer - UP

Platfora - UP

diskSpace- Good

But I want to select only a few I tried giving in braces of to_entries[] but it didn't work.

Expected output:

Server1 - UP

Splunk -UP

Platfora - UP

Is there any way to pick only a few values. Appreciate your help. Thank you.

Answer 1

With the -r command-line option, the following transforms the given input to the desired output, and is perhaps close to what you're looking for:

.components
| to_entries[]
| select(.key == ("server1", "Splunk", "Platfora"))
| "\(.key)- \(.value.status)"

If the list of components is available as a JSON list, then you could modify the selection criterion accordingly, eg using IN (uppercase) or index .
