CHFN(1) User Commands CHFN(1)
NAME
chfn - change your finger information
SYNOPSIS
chfn [-f full-name] [-o office] ,RB [ -p office-phone] [-h home-phone] -u] [-v] [username]
DESCRIPTION
chfn is used to change your finger information. This information is stored in the /etc/passwd file, and is displayed by the finger pro-
gram. 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.
chfn is used to change local entries only. Use ypchfn, lchfn or any other implementation for non-local entries.
COMMAND LINE
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.
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.
OPTIONS
-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
Print a usage message and exit.
-v, --version
Print version information and exit.
EXIT STATUS
Returns 0 if operation was successful, 1 if operation failed or command syntax was not valid.
