JQ query extraction - jq

Question

First off thanks to everyone who takes time to answer questions for us who are learning or struggling. I have this code that works as I need, I had help from knittl earlier.
jq -r '["Username", "Full name", "Superuser", "Active"],
> (.User[]
> | select(.is_superuser)
> | [ .username, .full_name, .is_superuser, .is_active ])
> | #csv' lbc.noprod1.xxx.json > lbc.noprod1.xxx_Superuser.csv
I have tried to adjust it so that I can use the same concept but to get other information and have this
jq -r '["Interface Name", "Vlan ID", "IP address", "Subnet Mask"],
(.ServiceEngine[].data_vnics[].vlan_interfaces[]
| [ .if_name, .vlan_id])
(.ServiceEngine[].data_vnics[].vlan_interfaces[].vnic_networks[].ip[].ip_addr[]
| [.addr])
(.ServiceEngine[].data_vnics[].vlan_interfaces[].vnic_networks[].ip[]
| [.mask])
| #csv' 20221004_lbc.prod1.xxx.json > 20221004_lbc.prod1.xxx_VNIC.csv
I receive the error below
jq: error: syntax error, unexpected '(', expecting $end (Unix shell quoting issues?) at , line 4:
(.ServiceEngine[].data_vnics[].vlan_interfaces[].vnic_networks[].ip[].ip_addr[]
jq: 1 compile error
If it helps this is an extract from the JSON with fields that aren't relevant removed but all formatting kept
"ServiceEngine": [
{
"data_vnics": [
{
"vlan_interfaces": [
{
"if_name": "bond1.109",
"vlan_id": 109,
"vnic_networks": [
{
"ctlr_alloc": false,
"ip": {
"ip_addr": {
"addr": "123.123.123.123",
"type": "V4"
},
"mask": 24
},
"mode": "STATIC"
}
],
"vrf_ref": "/api/vrfcontext/?tenant=admin&name=branch-pci-client-vlan109&cloud=Default-Cloud"
},
{
"dhcp_enabled": true,
"enabled": true,
"if_name": "bond1.1622",
"ip6_autocfg_enabled": true,
"is_mgmt": false,
"vlan_id": 1622,
"vnic_networks": [
{
"ctlr_alloc": false,
"ip": {
"ip_addr": {
"addr": "456.456.456.456",
"type": "V4"
},
"mask": 22
},
"mode": "STATIC"
}
],
"vrf_ref": "/api/vrfcontext/?tenant=admin&name=onprem-pci-prod-vlan1622&cloud=Default-Cloud"
},
As always if you have any tips and suggestions I would be greatful.
Kind regards

Answer 1

I think you are looking for this:
["Interface Name", "Vlan ID", "IP address", "Subnet Mask"],
(
.ServiceEngine[].data_vnics[].vlan_interfaces[]
| . as { $if_name, $vlan_id }
| .vnic_networks[].ip
| [ $if_name, $vlan_id, .ip_addr.addr, .mask]
)
| #csv
or
["Interface Name", "Vlan ID", "IP address", "Subnet Mask"],
(
.ServiceEngine[].data_vnics[].vlan_interfaces[]
| [ .if_name, .vlan_id ] + (.vnic_networks[].ip | [.ip_addr.addr, .mask])
)
| #csv
or
["Interface Name", "Vlan ID", "IP address", "Subnet Mask"],
(
.ServiceEngine[].data_vnics[].vlan_interfaces[]
| { if_name, vlan_id, ips: .vnic_networks[].ip }
| [ .if_name, .vlan_id, (.ips|.ip_addr.addr, .mask) ]
)
| #csv
All three generate the same CSV with one line per IP. Interface name and VLAN id will be printed multiple times if they contain more than one IP.
