Which of the following commands can an administrator use to change a user's password expiry information? (Select THREE).

The `usermod` command can be used with options like `-e` (expire date) or `-f` (inactive after password expires) to modify a user's password expiry settings.

The `passwd` command, when executed by the root user, allows manipulation of password aging parameters using options such as `-x` (maximum days), `-n` (minimum days), or `-i` (inactive days).

`chattr` is used to change file attributes on a Linux file system (e.g., making a file immutable), and it has no functionality related to user password expiry.

The `chage` command is specifically designed for changing user password aging information, providing detailed control over expiry dates, minimum/maximum days, and warning periods with options like `-E`, `-M`, `-m`, `-W`, and `-I`.

`chsh` is used to change a user's login shell, not their password expiry or aging information.
