# Script to automate the process of listing all the resources in an AWS account
#
# Below are the services that are supported by this script:
# 1. EC2
# 2. RDS
# 3. S3
# 4. CloudFront
# 5. VPC
# 6. IAM
# 7. Route53
# 8. CloudWatch
# 9. CloudFormation
# 10. Lambda
# 11. SNS
# 12. SQS
# 13. DynamoDB
# 14. VPC
# 15. EBS
#
# The script will prompt the user to enter the AWS region and the service for which the resources need to be listed.
#
# Usage: ./aws_resource_list.sh  <aws_region> <aws_service>
# Example: ./aws_resource_list.sh us-east-1 ec2

line 41: Aws_service is not converted to lower case .
aws_service=$(echo "$2" | tr '[:upper:]' '[:lower:]')
this should solve the issue

right

correct

Check my repo https://github.com/SanthoshKumar1903/Shell-Scripting-Projects
To make it lower case change the code as
aws_region=${1,,}
aws_service=${2,,}
This make the text to lowercase.
Also make sure to fix the spelling route53 in the case.

I created a Bash script that lists all major Google Cloud Platform (GCP) resources in a project using the gcloud CLI — adapted from an AWS resource listing script.
