The `passwd` command, while primarily for changing passwords, can also set password aging parameters like minimum/maximum days between changes, warning period, and inactive days with appropriate options.

The `chattr` command is used to change file system attributes on Linux files, such as making a file immutable, and has no relation to user password expiry.
