How can I use the command line interface of AWS and assume line command to assume a role in the AWS account?

 In the context of AWS, to assume a particular role in another AWS account by using the Command line interface of AWS, you can use the “aws sts assume-role” command. Here is the example given of how you can do so:-

Aws sts assume-role 
    --role-arn arn:aws:iam:::role/ 
    --role-session-name 

After running this above command, the AWS would return temporary credentials related to security such as access keys, secret access keys, and session tokens that you can use to request the service of AWS on behalf of the role which is assumed. These credentials generally have a limited lifetime, after which they would expire.

Here is the breakdown of the steps given:-

First, install and then configure the Command line interface of AWS.

Then you can run the “aws sts assume-role” command with the right parameters which would specify the ARN of the role for assuming and a session name.

Now you can attempt to retrieve the temporary credentials related to security measures that were provided by AWS in the command output for performing the actions on AWS resource in the targeted account.
