It will provide ec2-ssh script that will make ssh'ing to EC2 instance more sane.
Be sure to export AWS vars into your shell rc file(eg. .bashrc) 

export AWS_SECRET_KEY=yourkey
export AWS_SECRET_ACCESS_KEY=your_access_key

% ec2-ssh app1
# where app1 is the instance name of ec2 instance visible in AWS dashboard
# equivalent to
# ssh [email protected] where ec2-123-45-67-89.compute-1.amazonaws.com is the public URL to app1 name in corresponding AWS account.

% ec2-ssh root@appserver
% ec2-ssh deploy@nginx2 sudo restart nginx

% ec2-ssh -l 
will list out all the active ec2 instances

% ec2-ssh -a site1 "ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAqVeNqpSJEhGrFvJeZdLyOXVAFORF0jj3/voX5wZ6rCXHXOXWVDcbVDryH5h6iGAfAeGfs11oTkh9i7L4KQC+mx8nInQy92LwTDMV8bdU1LGl6nCYOez8r0V+YlsSPem23byQga6IKCGUk/DwVpjFUESY86JCA7hMHsiSmCYsai8ovr8euFbZ8ZbHACfC3RtzDN8nx1p3Tuk2Ka0aEMKyAzQVRs9fW48sJ5zGJexY1nmZt5dXF1vb4u8qCHh7Z7+iLPo5sX4Td813XgAZ1FOMajyShgf5HBf8T4IUNbrN5Uf3pLTeVDLIDwqFpDQ2lSaurZ4umVLd11OALQ1TssbwwQ== [email protected]"
