Hi there,
I am using simple-shell to build a shell password manager.
Basically, for what I am doing I need

1. to associate a callback to the exit event
2. to prompt the user with an input after a specific command

The first is necessary to clean the memory and delete any clean text when closing the password manager.
The second is necessary because when the user starts the session, they have to input their master password and this cannot be an option like --password 47dryh283jk but has to be typed in a not visibile input. Ideally similar to how passwords are typed in openssl and similar tools.

I will take a look at your code and see if I can do something in order to open a pull request to add these features. Though, since you know your code, maybe you can do something quickly or suggest me how to approach the problem.

Thanks so much,
Francesco

I did a PR for the first problem

About the second, if you can give me some suggestion about how it is better to do it, it would be very appreciated.

@sullof Thanks for the PR.

reg. password/hidden inputs - I had not thought about it. If you can give me sometime, I will get back to you with a solution. If you have something in mind, please do suggest.

I was thinking to a feature like in this example in Inquirer. It would be very useful.
