ÜBERSICHT

       chfn [options] [LOGIN]

BESCHREIBUNG

       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.

OPTIONEN

       The options which apply to the chfn command are:

       -f, --full-name FULL_NAME
           ändert den vollständigen Namen des Benutzers.

       -h, --home-phone HOME_PHONE
           ändert die private Telefonnummer des Benutzers.

       -o, --other OTHER
           ändert sonstige GECOS-Informationen über den Benutzer. In diesem Feld werden Kontoinformationen
           anderer Anwendungen gespeichert. Es kann nur vom Systemadministrator verändert werden.

       -r, --room ROOM_NUMBER
           ändert die Raumnummer des Benutzers.

       -R, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR
           directory. Only absolute paths are supported.

       -u, --help
           zeigt die Hilfe an und beendet das Programm.

       -w, --work-phone WORK_PHONE
           ändert die berufliche Telefonnummer des Benutzers.

       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.
