The following line failed for me:
aws route53 list-hosted-zones | jq -r ".HostedZones[] | select(.Name == \"${zone_name}\") | .Id" | cut -d'/' -f3
I changed it to:
aws route53 list-hosted-zones|grep Id|cut -d'/' -f3|awk -F\" '{print $1}'
And it worked.

Nice script!
Just a comment: If someone has default aws cli output as text (and not json), then the comment by AAber should be applicable and some commands should be changed, like:

#   aws route53 list-hosted-zones | jq -r ".HostedZones[] | select(.Name == \"${zone_name}\") | .Id" | cut -d'/' -f3
   aws route53 list-hosted-zones|grep "${zone_name}" |cut -d'/' -f3|awk '{print $1}'

,

#aws route53 change-resource-record-sets --hosted-zone-id "$(hosted_zone_id)" --change-batch "$(change_batch)" | jq -r '.ChangeInfo.Id' | cut -d'/' -f3
aws route53 change-resource-record-sets --hosted-zone-id "$(hosted_zone_id)" --change-batch "$(change_batch)" | awk -F"/" ' { print $3 }'

and probably others ;-)

Hosted zone id, selected via a --query expression, from one of my scripts:

printf -v query_expr "HostedZones[?Name == '%s.'].[Id]" ${zone_name}   # "." after "%s" is intentional
full_zone_id=$( aws route53 list-hosted-zones --query "${query_expr}" --output=text )
hosted_zone_id=${full_zone_id##*/}   # strip leading "/hostedzone/"

Nice!

For your test of the variables I think you meant:

   [[ ! -z $record_name  ]] && echo "record_name is: $record_name" || exit 1
   [[ ! -z $record_value ]] && echo "record_value is: $record_value" || exit 1

Also to ensure the output is in JSON, just add to the top of the script:

 export AWS_DEFAULT_OUTPUT="json"

I'm new to the aws thing, just need to be able to add a lot of cnames really quickly, so i found this script. Where does the "$ROUTE53_DEFAULT_HOSTED_ZONE_NAME" come from? Is that something that the aws cli provides automatically once it's configured properly?

@inscrutabledude
I believe you need to export it before running the script.

Awesome work!

I'd recommend to use UPSERT action. In this case non-existing records will be created. Existing records will get updated.
action=${action:-UPSERT}
