find all S3 objects without tags

Question

Hello,  
  
Considering the following Windows 10 bash command from a .bat file (using AWS CLI), that finds all the S3 keys for specified (tagKey,tagValue), could you please specify the command to get all the S3 keys without any tag ?  
```
for /f "tokens=*" %%a in ('aws s3api list-objects-v2 --bucket  --prefix  --no-cli-auto-prompt --query Contents[*].[Key] --output text') do (
	for /f "tokens=*" %%b in ('aws s3api get-object-tagging --bucket  --key %%a --no-cli-auto-prompt --query TagSet[?"Key==''&&Value==''"].Key --output text') do (
		@echo %%a >> 
	)
)
```
Thank you,

Please see the more clear syntax
```
for /f "tokens=*" %%a in ('aws s3api list-objects-v2 --bucket  --prefix  --no-cli-auto-prompt --query Contents[*].[Key] --output text') do (
	for /f "tokens=*" %%b in ('aws s3api get-object-tagging --bucket  --key %%a --no-cli-auto-prompt --query "TagSet[0]==null" --output text') do (
		if %%b==True @echo %%a >> 
	)
)
```

Hello,

At this moment AWS released a new feature to query tags. It is called [Amazon S3 Metadata](https://aws.amazon.com/about-aws/whats-new/2025/01/amazon-s3-metadata-generally-available/), and it works as described [here](https://aws.amazon.com/blogs/aws/introducing-queryable-object-metadata-for-amazon-s3-buckets-preview/)

Have a good day,

find all S3 objects without tags
