jq's Issues

jq

Count

jq '.type_m1_xlarge | length' ~/.ansible/tmp/ansible-ec2.cache

Change PO to never reprovision

jq '.compute[].reprovision = "never"'  file.json

Slurp json all together

jq -s add attributes.json build.json compute.json

Change an attribute

jq '.attributes.stackid = "Something"' attributes.json

Change an attribute and slurp

jq -s 'add | .attributes.stackid = "Something"' attributes.json build.json compute.json

jq -s 'add | .attributes.stackid = "something" | .attributes.customer_name = "Something"' attributes.json build.json compute.json

Use file and var

jq -s -f compile.jq attributes.json build.json compute.json --arg customer "something"

add | 
.attributes.stackid = $customer | 
.attributes.customer_name = $customer | 
.attributes.name = $customer | 
.attributes.ssh_keypair = "infra_" + $customer

Change file in place

jq -S '.compute[].reprovision = "never"' $1.json > $1.json.never ; mv $1.json.never $1.json

Wrong tree

    jq '.compute | .[] | .reprovision = "never"'  file.json
