Việc xác định tiêu đề bằng tay là không tối ưu! Việc bỏ qua tiêu đề cũng không tối ưu.
TL; DR
dữ liệu
[{ "name": "George", "id": 12, "email": "george@domain.com" },
{ "name": "Jack", "id": 18, "email": "jack@domain.com" },
{ "name": "Joe", "id": 19, "email": "joe@domain.com" }]
kịch bản
[.[]| with_entries( .key |= ascii_downcase ) ]
| (.[0] |keys_unsorted | @tsv)
, (.[]|.|map(.) |@tsv)
làm thế nào để chạy
$ < data jq -rf script | column -t
name id email
George 12 george@domain.com
Jack 18 jack@domain.com
Joe 19 joe@domain.com
Tôi tìm thấy câu hỏi này trong khi tóm tắt một số dữ liệu từ các dịch vụ web của amazon. Vấn đề tôi đang giải quyết, trong trường hợp bạn muốn có một ví dụ khác:
$ aws ec2 describe-spot-instance-requests | tee /tmp/ins |
jq --raw-output '
# extract instances as a flat list.
[.SpotInstanceRequests | .[]
# remove unwanted data
| {
State,
statusCode: .Status.Code,
type: .LaunchSpecification.InstanceType,
blockPrice: .ActualBlockHourlyPrice,
created: .CreateTime,
SpotInstanceRequestId}
]
# lowercase keys
# (for predictable sorting, optional)
| [.[]| with_entries( .key |= ascii_downcase ) ]
| (.[0] |keys_unsorted | @tsv) # print headers
, (.[]|.|map(.) |@tsv) # print table
' | column -t
