Task: As part of the temporary assignment to the Nautilus project, a developer named jim requires access for a limited duration. To ensure smooth access management, a temporary user account with an expiry date is needed.

ssh banner@172.16.238.12
sudo useradd -e 2024-03-28 jim
sudo chage -l jim

sudo useradd -e 2024-03-28 jim  <- The -e allows for the setting of the date upon which the account will automatically expire.

sudo chage -l jim <- Verify the expiration for the user we just add 'jim' has the correct expiration date.

What happens after the expiry date?
- The user will not be able to login after the date has passed
- The account will be disabled, but it is not deleted
- The account can be re-enabled by extending the expiry date, use the same command as above with a date in the future

Optional Flags:
-s /sbin/nologin <- prevent shell access
-m <- create a home directory
-d /custom/path <- specify a home directory path

Final Command if using optional flags would be:
sudo adduser -e 2024-03-28 -m -s /sbin/nologin jim
