NOME
chfn - change real user name and informationSINOSSI
- 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.
