There is no way to get all the resources in an AWS account with a single command or anything like that. The reason for this is, in few services like IAM and Billing dashboard, there is no concept of region. So, how will you filter them out?
But there is a service called AWS Config which let's you check the changes being made in your AWS account on individual services. You can activate AWS Config to do a similar task.
Also, I came across this AWS Retriever project in GitHub which looks a pretty good, one stop solution. The application looks like this, you can makes changes to code if you want by forking it.
