- You can list custom tags in AWS CLI using the
describe-tagscommand for EC2 resources or thelist-tagscommand for Lambda resources. - You can use the
get-resourcescommand of theresourcegroupstaggingapito return all the tagged or previously tagged resources that are located in the specified Region for the AWS account. - You can redirect the output of the AWS CLI command to a file using the
>operator. - The output of the
get-resourcescommand is organized into sections, with each section representing a resource and its associated tags. - You can filter the output of the
get-resourcescommand by tag using the--tag-filtersoption. - You can use the
--queryoption of theget-resourcescommand to filter the output using a JMESPath query expression. - In Cost Explorer, you can filter your AWS costs by tag key and value.
