Aws Pocketknife

Why?

Have you ever find yourself going through the aws cli documentation page over and over again just to remember the right syntax or argument(s) for that command that you wanna run? Do you feel that you are more productive from the command line? Are you tired of having to open private browser windows or even a different browser to work with multiple aws accounts?

What?

Command line tools to make aws administration a little bit easier and faster than using the aws console. It also helps to script some AWS tasks such as cleaning up old AMIs along its snapshots or cleaning up manual RDS snapshots or even creating a manual snapshot for a particular RDS.

These commands are also handy if you have multiple aws accounts to manage, since you can't have multiple tabs open for different accounts in a web browser. The only way would be to use diffente browsers or open incognito windows.

The aws cli allows you to setup profiles for each account. (see http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html#cli-multiple-profiles) After creating the profiles, you just export the environment variable AWS_PROFILE to specify the account you wish to use.
