从AWS EC2实例检索确切的标签值

Question

I'm using the below command to get the AWS EC2 instance tag value for the tag name called 'Name', but the problem is that I also have a tag called 'Cluster Name' so the code below outputs the tag values for both 'Name' and 'Cluster Name' tags.

How can I make it so that I only retrieve the tag value for 'Name' tag?

aws ec2 describe-tags --region us-east-1 --filters "Name=resource-id,Values=i-01159fca884xxxxxx" | grep -2 Name | grep Value | tr -d ' ' | cut -f2 -d: | tr -d '"' | tr -d ','

This works on a Mac (quotation formatting might need to change for Windows):v

aws ec2 describe-instances --filter Name=instance-id,Values=i-xxx --query 'Reservations[].Instances[].Tags[?Key==`Name`].Value' --output text
