NOME

       chfn - change real user name and information

SINOSSI

       chfn [-f full_name] [-r room_no] [-w work_ph] [-h home_ph] [-o other]
            [user]

DESCRIZIONE

       The chfn command changes user fullname, office number, office
       extension, and home phone number information for a users account. This
       information is typically printed by finger(1) and similar programs. A
       normal user may only change the fields for her own account, subject to
       the restrictions in /etc/login.defs. (The default configuration is to
       prevent users from changing their fullname.) The superuser may change
       any field for any account. Additionally, only the superuser may use the
       -o option to change the undefined portions of the GECOS field.

       These fields must not contain any colons. Except for the other field,
       they should not contain any comma or equal sign. It is also recommended
       to avoid non-US-ASCII characters, but this is only enforced for the
       phone numbers. The other field is used to store accounting information
       used by other applications.

       Se nessuna delle opzioni è selezionata, chfn opera in maniera
       interattiva, chiedendo allutente il valore da impostare per ogni campo.
       Inserire un nuovo valore per sostituire il contenuto attuale, oppure
       lasciare la linea vuota per non cambiarlo. Il valore attuale è mostrato
       tra le parentesi [ ]. Senza alcuna opzione, chfn, chiede laccount sul
       quale operare.

CONFIGURATION

       The following configuration variables in /etc/login.defs change the
       behavior of this tool:

       CHFN_RESTRICT (string)
           This parameter specifies which values in the gecos field of the
           /etc/passwd file may be changed by regular users using the chfn
           program. It can be any combination of letters f, r, w, h, for Full
           name, Room number, Work phone, and Home phone, respectively. For
           backward compatibility, yes is equivalent to rwh and no is
           equivalent to frwh. If not specified, only the superuser can make
           any changes. The most restrictive setting is better achieved by not
           installing chfn SUID.

FILE

       /etc/login.defs
           Shadow password suite configuration.
