NOME

       chfn - cambia il nome dell'utente e altre informazioni

SINOSSI

       chfn [opzioni] [LOGIN]

DESCRIZIONE

       The chfn command changes user fullname, office room number, office phone number, and home phone number
       information for a user's 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.

OPZIONI

       The options which apply to the chfn command are:

       -f, --full-name FULL_NAME
           Cambia il nome completo dell'utente.

       -h, --home-phone HOME_PHONE
           Cambia il numero di telefono di casa dell'utente.

       -o, --other OTHER
           Cambia il campo GECOS per le altre informazioni. Questo campo viene utilizzato per memorizzare
           informazioni di «accounting» usate da altre applicazioni, e può essere modificato solo dal super
           utente.

       -r, --room ROOM_NUMBER
           Cambia il numero della stanza dell'utente.

       -R, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR
           directory.

       -u, --help
           Mostra un messaggio di aiuto ed esce.

       -w, --work-phone WORK_PHONE
           Cambia il numero di telefono di lavoro dell'utente.

       If none of the options are selected, chfn operates in an interactive fashion, prompting the user with the
       current values for all of the fields. Enter the new value to change the field, or leave the line blank to
       use the current value. The current value is displayed between a pair of [ ] marks. Without options, chfn
       prompts for the current user account.

CONFIGURAZIONE

       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
           Configurazione del pacchetto password shadow

       /etc/passwd
           Informazioni sugli account utente.
