Prerequisites

• AWS CLI https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html

• Active AWS access keys - access key ID and secret access key

Configure AWS CLI

Use command aws configure

aws configure

AWS Secret Access Key [MPLE]:
Default region name [us-east-1]:
Default output format [None]:

Check domains using route53domains command

aws route53domains check-domain-availability --output=text --domain-name 

Example

aws route53domains check-domain-availability --output=text --domain-name some.com
UNAVAILABLE

Example

aws route53domains check-domain-availability --output=text --domain-name random12345.com
AVAILABLE

Create an alias to find domains quickly

Create an alias to map to the command seen above.

alias domain=’aws route53domains check-domain-availability --output=text --domain-name’

Use the alias instead of typing the whole command in the future.

domain some.com
UNAVAILABLE

Similarly, you can create a shell function or script, or macro to run the entire command efficiently.
