chfn

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.

       -v, --version
	      Print version information and exit.
