list subnets

list instances by subnet

aws ec2 --query 'Subnets[*].[SubnetId, CidrBlock]' describe-subnets --output text | while read subnet cidr
do
echo Subnet ${subnet} ${cidr}
for i in `aws ec2 --query 'Reservations[*].Instances[*].[InstanceId]' describe-instances --output text --filter "Name=subnet-id,Values=${subnet}"`
 do
 name=`aws ec2 --query 'Tags[*].[Value]' describe-tags --filter "Name=resource-id,Values=${i}" "Name=key,Values=Name" --out text`
 echo -n ${name} " "
 aws ec2 --query 'Reservations[*].Instances[*].[State.Name, InstanceId, ImageId, PrivateIpAddress, PublicIpAddress, InstanceType]' describe-instances --output text --filter "Name=subnet-id,Values=${subnet}" "Name=instance-id,Values=${i}"

Good ref for getting tags : http://docs.aws.amazon.com/cli/latest/reference/ec2/describe-tags.html

getting tags example:

aws ec2 --query 'Tags[*].[Value]' describe-tags --filter "Name=resource-id,Values=<id>"

just an instance's name:

aws ec2 --query 'Tags[*].[Value]' describe-tags --filter "Name=resource-id,Values=<id>" "Name=Key,Value=Name" --out text
