set -x

# AWS s3 buckets
echo "print the list of s3 buckets"
aws s3 ls

# AWS ec2 instance 

echo "print the list of ec2 instance"
aws ec2 describe-instances | jq '.Reservations[].Instances[].InstanceId'
#AWS list of lambda

echo "print the list of lambda function"
aws lambda list-functions

#AWS IAM list

echo "print the list of IAM role "

aws iam list-users

step 4: give permission to the file

chmod 777 usage.sh

step 5: run the command

./usage.sh

you can see the output below
