aws-profile

This command is a really simple wrapper around AWS Vault which adds a local config file to save keystrokes and help prevent mistakes. From their README:

AWS Vault is a tool to securely store and access AWS credentials in a development environment.

To run a command (e.g. S3 list) under a "home" profile with AWS Vault, you run:

$ aws-vault exec home -- aws s3 ls

With aws-profile, you can save your profile in a .awsprofilerc file like so:

profile: home

Then, you can just run:

$ aws-profile s3 ls

Or even:

$ awsp s3 ls

Note that it assumes you want to run the aws executable. If you don't, you can use a double dash (--):

$ aws-profile -- env
# runs 'env'

Installation

$ npm install --global @stewartml/aws-profile

More details

This script uses rc-yaml for configuration, so your .awsprofilerc file can be in YAML, JSON, or INI format.

You can put the config anywhere rc looks by default, including the awsprofile_profile environment variable, but not including command line options, as they would interfere with the command.

Here's what it would look like to use an environment variable:

$ awsprofile_profile=home awsprofile s3 ls

Not sure why you'd do that though...
