With jq I can do this:
[me#linux]$ cat /tmp/json | jq '.module | .data | keys'
[
"container_C",
"delivery_3",
"delivery_d43597338a",
"delivery_dfdaf8a8a",
"floatTips_4",
"item_i7790e0f9",
"item_i77997d6b",
"item_i7799f86e",
"leftContainer_CL",
"listHeader_H",
"location_2",
"orderSummary_6",
"orderTotal_8",
"package_p43597338a",
"package_pfdaf8a8a",
"rightContainer_CR",
"root_0",
"shop_43597338a_s2c",
"shop_fdaf8a8a_s23f9",
"voucherInput_7"
]
I need to get orderTotal_8 but please note that the number 8 is always changing, so it can be orderTotal_10 or orderTotal_3 etc... How can I get this key with pure jq command if possible, without the help of grep / awk ? So the result should be like this orderTotal_8

Answer 1

If you want to form a subarray of items satisfying some condition, just add map(select( CONDITION )) to the pipeline, e.g.
.module | .data | keys | map(select(test("^orderTotal_")))
If you just want a stream of the items matching the condition, then you could first form the stream, and then make the selection:
.module | .data | keys[] | select(test("^orderTotal_"))
For efficiency and other reasons, you might want to consider using keys_unsorted instead of keys.
