Usage: ec2ssh [ec2ssh options] [ssh arguments] destination [command [argument ...]]

Connect to an EC2 instance directly using SSH or via the EC2 Instance Connect
Endpoint (EICE), by the instance ID, private, public, or IPv6 address, private
DNS name, or name tag, using ephemeral SSH keys.

  Example - Connect to an instance using the instance ID:
     $ ec2ssh -l ec2-user i-0123456789abcdef0

  Example - Connect to an instance using a name tag with the public IP address:
     $ ec2ssh -p 2222 --address-type public ec2-user@app01

  Example - Connect to an instance using its private DNS name via an EICE tunnel:
     $ ec2ssh --use-eice ip-10-0-0-1

  Example - Use any SSH options and arguments as usual:
     $ ec2ssh --use-eice -L 8888:127.0.0.1:8888 -N -i ~/.ssh/id_rsa_alt -o VisualHostKey=Yes app01
