SAWS
A supercharged AWS command line interface (CLI)
..., subcommands, and options the AWS CLI provides, SAWS supports auto-completion of your AWS resources. Currently, bucket names, instance ids, and instance tags are included, with additional support for more resources under development. Sometimes you're not quite sure what specific command/subcommand/option combination you need to use. In such cases, browsing through several combinations with the help command line is cumbersome versus browsing the online AWS CLI docs through a web browser.
