I need to delete multiple keys at once from some JSON (using jq), and I'm trying to learn if there is a better way of doing this, than calling map and del every time. Here's my input data:
test.json
[ {"label": "US : USA : English","Country": "USA","region": "US","Language": "English","locale": "en","currency": "USD","number": "USD" }, {"label": "AU : Australia : English","Country": "Australia","region": "AU","Language": "English","locale": "en","currency": "AUD","number": "AUD" }, {"label": "CA : Canada : English","Country": "Canada","region": "CA","Language": "English","locale": "en","currency": "CAD","number": "CAD" }]For each item, I want to remove the number, Language, and Country keys. I can do that with this command:
$ cat test.json | jq 'map(del(.Country)) | map(del(.number)) | map(del(.Language))'That works fine, and I get the desired output:
[ {"label": "US : USA : English","region": "US","locale": "en","currency": "USD" }, {"label": "AU : Australia : English","region": "AU","locale": "en","currency": "AUD" }, {"label": "CA : Canada : English","region": "CA","locale": "en","currency": "CAD" }]However, I'm trying to understand if there is a jq way of specifying multiple labels to delete, so I don't have to have multiple map(del()) directives?
