This command lists the EC2 instance id and the tag name using query.
aws ec2 describe-instances \ --query 'Reservations[].Instances[].[InstanceId,Tags[?Key==Name]|[0].Value]' \ --profile tfc \ --region us-east-2 \ --output text |
aws ec2 describe-instances \ --query 'Reservations[].Instances[].[InstanceId,Tags[?Key==Name]|[0].Value]' \ --profile tfc \ --region us-east-2 \ --output text
Output:
i-xxxxxxxxxxxxxxxxx server-one i-xxxxxxxxxxxxxxxxx server-two i-xxxxxxxxxxxxxxxxx server-three |
i-xxxxxxxxxxxxxxxxx server-one i-xxxxxxxxxxxxxxxxx server-two i-xxxxxxxxxxxxxxxxx server-three
|[0].Value insures output is one instance record per line.

Instead of using AWS and JQ to get the snapshot names, you can do it with a single command using –query.
Here are the previous commands.
/usr/bin/aws lightsail get-instance-snapshots --region us-east-1 --profile default > $snaps cat $snaps | jq -r '.instanceSnapshots[] | .name' > $names |
/usr/bin/aws lightsail get-instance-snapshots --region us-east-1 --profile default > $snaps cat $snaps | jq -r '.instanceSnapshots[] | .name' > $names
Using query.
aws lightsail get-instance-snapshots \ --query 'instanceSnapshots[*].[name]' \ --region us-east-1 \ --profile default \ --output text > $names |
aws lightsail get-instance-snapshots \ --query 'instanceSnapshots[*].[name]' \ --region us-east-1 \ --profile default \ --output text > $names

How to display AWS EC2 instance statuses.
aws ec2 describe-instance-status \ --query 'InstanceStatuses[].[InstanceId,SystemStatus.Status]' \ --include-all-instances \ --region us-east-2 --profile abcdef \ |
aws ec2 describe-instance-status \ --query 'InstanceStatuses[].[InstanceId,SystemStatus.Status]' \ --include-all-instances \ --region us-east-2 --profile abcdef \
Query and Filter.
aws ec2 describe-instance-status \ --query 'InstanceStatuses[].[InstanceId,SystemStatus.Status]' \ --filter 'Name=instance-state-name,Values=stopped' \ --region us-east-2 --profile abcdef \ |
aws ec2 describe-instance-status \ --query 'InstanceStatuses[].[InstanceId,SystemStatus.Status]' \ --filter 'Name=instance-state-name,Values=stopped' \ --region us-east-2 --profile abcdef \
Filter event.code equal to instance-reboot.
aws ec2 describe-instance-status \ --query 'InstanceStatuses[].[InstanceId,SystemStatus.Status]' \ --filter 'Name=eventcode,Values=instance-reboot' \ --region us-east-2 --profile abcdef \ |
aws ec2 describe-instance-status \ --query 'InstanceStatuses[].[InstanceId,SystemStatus.Status]' \ --filter 'Name=eventcode,Values=instance-reboot' \ --region us-east-2 --profile abcdef \
