Hi @jim3mar. Thanks for the PR.

The addition of --ami_tags is nice (would prefer it to be --ami-tags) but we cannot change the positional argument to require --ami_id.

Would you mind modifying this PR to fix those 2 things so I can merge it?

Hi @pas256

I have modified the ami-id for backward compatibility.

When setting the special ami-id, the tags should not be setting.
When the ami-id is "-", the tags can work OK.

distami --region us-east-1 --to us-west-1 ami-abcd1234
distami --region us-east-1 --to us-west-1 --ami-tags Name:Linux,Version:3 -
