I thought chage was for password aging?

I feel like `chage` is more about password aging, so I don't think it would work for changing the shell.

I practiced a similar question where we had to change user settings, and `usermod -s` definitely came up as the right command.

I think `useradd -s` is also related to setting the shell, but I can't recall if it applies to existing users like Maria.

I remember something about using `usermod -s` to change the shell, but I'm not entirely sure if that's the only command needed.

Hmm, I'm a little confused on the impact of credit memos on inventory. I'll need to review my notes to make sure I understand the distinction between the two types.

I think this question is testing our understanding of how consensus algorithms incentivize miners. The key is to focus on the rewards and incentives, not the specific payment method.

I feel like there was a similar question in our practice test that confirmed HTTP supports both.
