CHFN(1)                         User Commands                        CHFN(1)

NAME         top

       chfn - change your finger information

SYNOPSIS         top

       chfn [-f full-name] [-o office] [-p office-phone] [-h home-phone]
       [-u] [-v] [username]

DESCRIPTION         top

       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.

OPTIONS         top

       -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.

CONFIG FILE ITEMS         top

       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.

EXIT STATUS         top

       Returns 0 if operation was successful, 1 if operation failed or
       command syntax was not valid.
