CHFN(1) User Commands CHFN(1)

NAVN

chfn - change real user name and information

SYNOPSIS

chfn [tilvalg] [LOGIND]

BESKRIVELSE

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.

TILVALG

Tilvalgende som gælder for kommandoen chfn er:

-f, --full-name NAVN

Ændr brugerens navn.

-h, --home-phone TELEFONNUMMER

Ændr brugerens telefonnummer.

-o, --other ANDEN

Ændr brugerens anden GECOS-information. Dette felt bruges til at gemme kontoinformation brugt af andre programmer, og kan kun ændres af en superbruger.

-r, --room VÆRELSESNUMMER

Ændr brugerens værelsesnummer.

-R, --root CHROOT_DIR

-w, --work-phone ARBEJDSTELEFON

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.

KONFIGURATION

De følgende konfigurationsvariabler i /etc/login.defs ændrer opførelsen for dette værktøj:

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.

FILER

/etc/login.defs
Shadow password suite configuration.

/etc/passwd

Information om brugerkonto.
