CHFN(1) User Commands CHFN(1)
chfn - change your finger information
chfn [-f full-name] [-o office] [-p office-phone] [-h home-phone]
[-u] [-v] [username]
chfn is used to change your finger information. This information is
stored in the /etc/passwd file, and is displayed by the finger
program. The Linux finger command will display four pieces of
information that can be changed by chfn: your real name, your work
room and phone, and your home phone.
Any of the four pieces of information can be specified on the command
line. If no information is given on the command line, chfn enters
interactive mode.
In interactive mode, chfn will prompt for each field. At a prompt,
you can enter the new information, or just press return to leave the
field unchanged. Enter the keyword "none" to make the field blank.
chfn supports non-local entries (kerberos, LDAP, etc.) if linked with
libuser, otherwise use ypchfn, lchfn or any other implementation for
non-local entries.
-f, --full-name full-name
Specify your real name.
-o, --office office
Specify your office room number.
-p, --office-phone office-phone
Specify your office phone number.
-h, --home-phone home-phone
Specify your home phone number.
-u, --help
Display help text and exit.
-v, --version
Display version information and exit.
chfn reads the /etc/login.defs(5) configuration file. Note that the
configuration file could be distributed with another package (e.g.
shadow-utils). The following configuration items are relevant for
chfn(1):
CHFN_RESTRICT string
Indicate which fields are changeable by chfn.
The boolean setting "yes" means that only the Office, Office
Phone and Home Phone fields are changeable, and boolean setting
"no" means that also the Full Name is changeable.
Another way to specify changeable fields is by abbreviations: f =
Full Name, r = Office (room), w = Office (work) Phone, h = Home
Phone. For example, CHFN_RESTRICT "wh" allows changing work and
home phone numbers.
If CHFN_RESTRICT is undefined, then all finger information is
read-only. This is the default.
Returns 0 if operation was successful, 1 if operation failed or
command syntax was not valid.
