I am trying to parse an output from aws cli and pass it into another argument. I am trying to accomplish this with sed and am stuck on how to approach it, I have read other posts but can't seem to figure it out.
output:
{
"LoadBalancers": [
{
"Type": "network",
"Scheme": "internet-facing",
"IpAddressType": "ipv4",
"VpcId": "vpc-3ac0fb5f",
"AvailabilityZones": [
{
"LoadBalancerAddresses": [
{
"IpAddress": "35.161.207.171",
"AllocationId": "eipalloc-64d5890a"
}
],
"ZoneName": "us-west-2b",
"SubnetId": "subnet-5264e837"
}
],
"CreatedTime": "2017-10-15T22:41:25.657Z",
"CanonicalHostedZoneId": "Z2P70J7EXAMPLE",
"DNSName": "my-network-load-balancer-5d1b75f4f1cee11e.elb.us-west-2.amazonaws.com",
"LoadBalancerName": "my-network-load-balancer",
"State": {
"Code": "provisioning"
},
"LoadBalancerArn": "arn:aws:elasticloadbalancing:us-west-2:123456789012:loadbalancer/net/my-network-load-balancer/5d1b75f4f1cee11e"
}
]
}
The string i am trying to capture is
arn:aws:elasticloadbalancing:us-west-2:123456789012:loadbalancer/net/my-network-load-balancer/5d1b75f4f1cee11e
and pass it into the following command:
aws elbv2 delete-load-balancer --load-balancer-arn <the arn extracted from the previous output>
If you provide a solution a small explanation would be helpful as well. Thanks in advance for your help!

Answer 1

If the output is json format, sed is not recommended to parse the json/xml...input.
You can use jq in shell, for your example, you can do:
..cmd to get yourOutput..|jq '.LoadBalancers[0].LoadBalancerArn'
