Hi @Jimilian, this was really helpful to me! Thanks for writing/publishing it!

I was wondering if you'd be willing to attach a license to it (or if there is one attached that I didn't notice)? I'm hoping to use it in a small bash script for managing AWS credentials. In my draft right now, I reference your Stackoverflow profile as the creator of this piece of code.

Was planning to distribute that under the MIT License, but want to make sure that's alright with you, and if not, I won't!
