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.
ПАРАМЕТРЫ
The options which apply to the
chfn
command are:
-f, --full-name FULL_NAME
-
Изменяет ФИО пользователя.
-h, --home-phone HOME_PHONE
-
Изменяет номер домашнего телефона пользователя.
-o, --other OTHER
-
Изменяет другую информацию GECOS о пользователе. Эта часть используется для хранения информации об учётной записи, используемой другими приложениями, и может изменяться только суперпользователем.
-r, --room ROOM_NUMBER
-
Изменяет номер комнаты пользователя.
-R, --root CHROOT_DIR
-
Apply changes in the
CHROOT_DIR
directory and use the configuration files from the
CHROOT_DIR
directory.
-u, --help
-
Показать краткую справку и закончить работу.
-w, --work-phone WORK_PHONE
-
Изменяет номер рабочего телефона пользователя.
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.
НАСТРОЙКА
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.
