The command aws iam get-policy --policy-arn arn:aws:iam::aws:policy/${policy_name} is used to retrieve information about an IAM (Identity and Access Management) policy in AWS.

Here's an explanation of the command:

• aws: This is the AWS Command Line Interface (CLI) command to interact with AWS services.
• iam: This specifies the IAM service, which is responsible for managing user identities and access to AWS resources.
• get-policy: This is the sub-command used to retrieve information about an IAM policy.
• --policy-arn: This option specifies the Amazon Resource Name (ARN) of the policy to retrieve. The ARN is a unique identifier for AWS resources and in this case, it is the ARN of the IAM policy.
• arn:aws:iam::aws:policy/${policy_name}: This is the ARN of the IAM policy to retrieve. The ${policy_name} is a placeholder for the actual name of the policy you want to retrieve. You need to replace ${policy_name} with the name of the policy you want to retrieve.

By running this command and providing the correct ARN of the policy, you will receive information about the IAM policy, such as its name, policy document, and other metadata.
