Do not force a user to specify the PIN/PUK/mgmt-key on the command line. Instead, query the user to supply them through stdin when required for the requested operation. This is both more user friendly and more secure, since the secrets do not end up in the shell history and/or visible to shoulder-surfers on the terminal.
