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_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.
