How to rename ec2-instance name

Question

I want to rename 100 ec2 instances using cli how to do that ?

This will show all instance names :

aws ec2 describe-instances --filters "Name=tag:productionpriority,Values=productionpriority" --query 'Reservations[].Instances[].[ [Tags[?Key==`Name`].Value][0][0],PublicIpAddress, PrivateIpAddress, InstanceId, InstanceType, Placement.AvailabilityZone]'

But how to modify Instance name ie replace old name with new one ?
