Check if ACM Certificate is in-use with one-liner
You can use the one-liner though you need parallel
:)
AWS_DEFAULT_REGION=us-east-1 \
aws acm list-certificates \
| jq -r .CertificateSummaryList[].CertificateArn \
| parallel aws acm describe-certificate --certificate-arn {1} \
| jq -r '.Certificate|{domain:.DomainName,arn:.CertificateArn,type:.Type,issuer:.Issuer,inUseBy:.InUseBy}'
