AWS CLI whoami or how to troubleshoot aws cli permission issues

please ignore my code rage’ed profile name

[elixir1.2@stink rel]$ aws iam get-user --profile fuckyou

A client error (AccessDenied) occurred when calling the GetUser operation: User: arn:aws:iam::[REDACTED]:user/[REDACTED] is not authorized to perform: iam:GetUser on resource: arn:aws:iam::[REDACTED]:user/[REDACTED]

I recently made a terrible assumption that source ~/.bashrc would actally clean out old env varriables. This lead to 20 minutes of going down the wrong path to try to troubleshoot why my aws cli was getting a permission denied. Lots of time could have been solved via the magical whoami command

the above command essentially uses the calling api to fetch the arn and tries to get info about it.
