I have the following data
Command output:
| jq '.rrsets[]'
{
"comments": [],
"name": "name1.",
"records": [
{
"content": "10.10.10.10",
"disabled": false
}
],
"ttl": 60,
"type": "A"
}
{
"comments": [],
"name": "name2.",
"records": [
{
"content": "20.20.20.20",
"disabled": false
}
],
"ttl": 60,
"type": "CNAME"
}
I want to get names where type is A.
Help, tell me how to do this?
| jq '.rrsets[] | with_entries(select(.key== "name", .value == "A"))'
{
"name": "name1."
}
{
"name": "name2.",
"type": "A"
}
Displays all the lines, but I only need where type = A
I'm not sure if this is what you are looking for, but wouldn't simply ... | select(.type == "A") do the trick?
... | jq '.rrsets[] | select(.type == "A")'
{
"comments": [],
"name": "name1.",
"records": [
{
"content": "10.10.10.10",
"disabled": false
}
],
"ttl": 60,
"type": "A"
}
Demo
And then just get the .name if you want only that (using -r to get rid of the JSON formatting):
... | jq -r '.rrsets[] | select(.type == "A").name'
name1.

I have a file like below (excerpt)
cat input.json
{
"Metrics": [
{
"Namespace": "CWAgent",
"MetricName": "disk_used_percent",
"Dimensions": [
{
"Name": "path",
"Value": "/aem"
},
{
"Name": "host",
"Value": "uat2-author01.uat.cloud.abc.com.au"
},
{
"Name": "device",
"Value": "mapper/aem-aem"
},
{
"Name": "fstype",
"Value": "ext4"
}
]
},
{
"Namespace": "CWAgent",
"MetricName": "mem_used_percent",
"Dimensions": [
{
"Name": "host",
"Value": "uat2-dispatch02.uat.cloud.abc.com.au"
}
]
}
]
}
As you can see the "Dimensions" is a list of json objects of varying length. I am required to print each objects under "Metrics" in a single line like below -
CWAgent|disk_used_percent|path:/aem|host:uat2-author01.uat.cloud.abc.com.au|device:mapper/aem-aem|fstype:ext4
CWAgent|mem_used_percent|host:uat2-dispatch02.uat.cloud.abc.com.au
I used this -
cat input.json | jq -r ".Metrics[] | .Namespace + \"|\" + .MetricName + \"|\" + (.Dimensions[] | .Name + \":\" + .Value + \"|\")"
And the output is like below:
CWAgent|disk_used_percent|path:/aem|
CWAgent|disk_used_percent|host:uat2-author01.uat.cloud.abc.com.au|
CWAgent|disk_used_percent|device:mapper/aem-aem|
CWAgent|disk_used_percent|fstype:ext4|
CWAgent|mem_used_percent|host:uat2-dispatch02.uat.cloud.abc.com.au|
As you can see, we are getting 4 lines for first object each having different object under Dimensions. Can anyone please suggest what will be the jq command to get desired output. I am novice in jq and wasted too much time on this experimenting.
Thanks,

You're looking for this:
jq -r '.Metrics[] | [.Namespace, .MetricName] + (.Dimensions | map("\(.Name):\(.Value)")) | join("|")' input.json
The question is similar to THIS, but the JSON structure is different.
In my usecase JSON has an arrays with key:value data:
{
"data":[
{
"name":"banana",
"tags":[
{
"id":"yellow"
},
{
"id":"long"
}
]
},
{
"name":"apple",
"tags":[
{
"id":"red"
},
{
"id":"round"
}
]
},
{
"name":"orange",
"tags":[
{
"id":"orange"
},
{
"id":"round"
},
{
"id":"colored"
}
]
}
]
}
What required is to filter the only elements that do not have certain keyword - "red" for instance.
When i use jq '.data[] | select(.tags[].id | index( "red" ))' it brings me the correct resut of 'apple' (as it has "id": "red") and 'orange' (as it has "id": "colored").
However, when i add the negation jq '.data[] | select(.tags[].id | index( "red" ) | not)' the results are more than strange, with elements' duplication, totally enigmatic.
How can i use jq to filter the result the way it returns only elements that do not have the exact match among the array values?
You can use all to give a condition all items must meet. Here, all values in .tags[].id must be unequal != to "red":
jq '.data[] | select(all(.tags[].id; . != "red"))'
{
"name": "banana",
"tags": [
{
"id": "yellow"
},
{
"id": "long"
}
]
}
{
"name": "orange",
"tags": [
{
"id": "orange"
},
{
"id": "round"
},
{
"id": "colored"
}
]
}
Demo
Add .name and use the -r option to only get the names:
jq -r '.data[] | select(all(.tags[].id; . != "red")).name'
banana
orange
Demo
index works on an array, your current filter does not pass index to an array, therefore you're getting other results then expected.
.data[] | select([ .tags[].id ] | index("red") | not)
Here we create an array with all the id's [ .tags[].id ] and use that array to check for red: | index("red") | not
The above filter gives the following output:
{
"name": "banana",
"tags": [
{
"id": "yellow"
},
{
"id": "long"
}
]
}
{
"name": "orange",
"tags": [
{
"id": "orange"
},
{
"id": "round"
},
{
"id": "colored"
}
]
}
Demo
If you want to exclude 'colored', use contains():
.data[] | select([ .tags[].id ] | contains(["red"]) | not)
{
"name": "banana",
"tags": [
{
"id": "yellow"
},
{
"id": "long"
}
]
}

Here is the jq I have, it just wants to build a new element and then append it to an array,
[.[] | . as { foo: $foo1, bar: $bar1} |
{
names: ([
$foo1 | range(0;length) as $i |
{ key: ($foo1[$i]) }
] + [{ key: $bar1 }])
} |
{
values: .names,
}
]
And suppose I have a json like this,
{
"foo":[
"key1",
"key2"
],
"bar": "key3"
}
This will generate a json file like this,
[
{
"values": [
{
"key": "key1"
},
{
"key": "key2"
},
{
"key": "key3"
}
]
}
]
But the element should be only appended when the $bar is not an empty string, can I do something like this?
[.[] | . as { foo1: $foo1, bar1: $bar1 if $bar != ""}
...
or do it when is appended,
names: ([
$foo1 | range(0;length) as $i |
{ key: ($foo1[$i]) }
] + [{ key: $bar1 }] | if $bar != "")
thanks in advance for any help!
You could just use select to filter out that case
jq '[{values: (.foo + [.bar | select(. != "")]) | map({key:.})}]'
If .bar == "key3", it prints
[
{
"values": [
{
"key": "key1"
},
{
"key": "key2"
},
{
"key": "key3"
}
]
}
]
If .bar == "", it prints
[
{
"values": [
{
"key": "key1"
},
{
"key": "key2"
}
]
}
]
If .bar does not exist, it will print
[
{
"values": [
{
"key": "key1"
},
{
"key": "key2"
},
{
"key": null
}
]
}
]
If in this last case you want to have the same result as with .bar == "", then change . != "" to values != "" in the filter to consider only values that are not null (or to strings != "" to only consider (non-empty) strings and disregard any other type).
I'd like to select the following node in a long json file.
The conditions are "locator": "mmc1" and "#name": "section-title". This nested structure makes the jq query very complex. Notice that I have to specify things like "locator" and "section-title" multiple times.
.. | .["$$"]?
| select((.[]? | ."#name" == "section-title"?) and (..[]? | .locator? | test("mmc[0-9]+")?))
| [
(..[]? | select(.locator? | test("mmc[0-9]+")?) | .locator)
, (.[] | select(."#name" == "section-title") | ._)
] | #tsv
Could anybody let me know how to make the query simpler in jq yet make sure its function is exact the same as the original query? Just making the following simplified test input producing the same output should not be considered as an equivalent query. Thanks.
...
"$$": [
{
"#name": "label",
"_": "Appendix A"
},
{
"#name": "section-title",
"$": {
"id": "sectitle0145"
},

},
{
"#name": "para",

"id": "p0210",
"view": "all"
},

}

}

}

}
]

See the output below.

If you want to get the "locator" value off of all objects unconditionally, you could use this:
..|objects.locator|strings
To find all objects with #name == "section-title" and select the _ value:
..|select(objects."#name" == "section-title")._
Putting it all together:
[(..|objects.locator|strings), (..|select(objects."#name" == "section-title")._)] | #tsv
https://jqplay.org/s/xHWg8aGSSS
The following is simpler in at least some respects, produces the desired result, and seems to reflect the requirements:
..
| .["$$"]?
| (.. | objects | .locator | strings | select(test("mmc[0-9]+")) ) as $locator
| (.. | objects | select(.["#name"] == "section-title") | ._) as $st
| [$locator, $st]
| #tsv
I want to parse terraform.tfstate (where openstack provider is used), to return instance name and it's internal + floating IP (if assigned).
First select what we are interested in:
jq -r '.modules?[]|.resources[]?|select(.type == "openstack_compute_floatingip_v2", .type == "openstack_compute_instance_v2")' < terraform.tfstate
For simplicity, pre-parsed example with the above part (one FIP and one instance):

Required is to take from "type": "openstack_compute_floatingip_v2" replace .primary.attributes.address and .fixed_ip and from corresponding .instance_id the .name.
So, sth like:
{"address": "209.66.89.143",
"fixed_ip": "10.10.10.5",
"name": "ctl01"}
Well, I came with an idea while using walk, but miss how to actually assign the proper value from corresponding instance id:
jq -r "$(cat floating.jq)" terraform.tfstate
floating.jq:
def walk(f):
. as $in
| if type == "object" then
reduce keys[] as $key
( {}; . + { ($key): ($in[$key] | walk(f)) } ) | f
elif type == "array" then map( walk(f) ) | f
else f
end;
.modules?[]|.resources[]?|select(.type ==
"openstack_compute_floatingip_v2", .type ==
"openstack_compute_instance_v2")|
.primary|walk( if type == "object" and .attributes.address then
.attributes.instance_id |= "REFERRED VALUE HERE") else . end)
Let's assume the two related objects are in a file named two.json. Then one way to merge the information from both objects is using the -s command-line option, e.g.
jq -s '
(.[0].primary.attributes | {address, fixed_ip})
+ {name: .[1].primary.attributes.name}' two.json
Output
With your example input, the output would be:
{
"address": "209.66.89.143",
"fixed_ip": "10.10.10.5",
"name": "ctl01"
}
