Python script to open IAM documentation in new tab

open_aws_iam_url.py

#!/usr/bin/env python
import sys
import webbrowser

service = sys.argv[1]
url = "https://docs.aws.amazon.com/IAM/latest/UserGuide/list_{}.html".format(service)

webbrowser.open(url, new=2)

Create a bash function in your shell rc file

function iam_help() { 
wget -q https://gist.githubusercontent.com/jolexa/4a08c85498992b2141ab91fba2f65d2f/raw/c33662e294bc7f4df24d892a33992c0527b8a6de/open_aws_iam_url.py && \
python ./open_aws_iam_url.py $1 && \
rm -f open_aws_iam_url.py
}

Then, whenever you need to know some AWS IAM docs, open the link:
Example, for ec2:* info: iam_help ec2
Example, for autoscaling:* info: iam_help autoscaling
