       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.

NAME

       chfn - change finger information

SYNOPSIS

       chfn [-D binddn] [-P path] [-f name] [-o office] [-p phone] [-h home_phone] [-m other] [-r service] [-q] [-u] [-v] [user]

DESCRIPTION

       chfn  is  used  to  change the user finger information. This are the users fullname, office room number, office phone number and home phone
       number. This information is stored in the /etc/passwd file and typically printed by finger(1) and similiar programs. A normal user may only
       change  the  fields  for  their own account, the super user may change the fields for any account. Also, only the super user may use the -o
       option to change the undefined portions of the GECOS field.

       If no information is given on the command line, chfn operates in an interactive fashion, prompting the user for each field.  Enter the  new
       value  to  change  the field, or leave the line blank to use the current value. Enter none or a blank only to remove the current value. The
       current value is displayed between a pair of [ ] marks.

       The only restrictions placed on the contents of the fields is that no control characters may be present, nor any of comma, colon, or  equal
       sign. The other field does not have this restriction, and is used to store accounting information used by other applications.

       This version of chfn is able to change the shell of local, NIS, NIS+ and LDAP accounts, if the permissions allow it.

OPTIONS

       -D, --binddn binddn
	      Use  the	Distinguished  Name binddn to bind to the LDAP directory.  The user will be prompted for a password for simple authentica-
	      tion.

       -P, --path path
	      The passwd and shadow files are located below the  specified  directory  path.  chfn  will  use  this  files,  not  /etc/passwd  and
	      /etc/shadow.   This  is  useful for example on NIS master servers, where you do not want to give all users in the NIS database auto-
	      matic access to your NIS server and the NIS map is build from special files.

       -f, --full-name
	      Specify your real name.

       -o, --office
	      Specify your office room number.

       -p, --phone
	      Specify your office phone number.

       -h, --home-phone
	      Specify your home phone number.

       -m, --other
	      Specify the undefined portions of the GECOS field.

       -r, --service
	      Specify the service where the GECOS field should be changed.  Supported services are files, ldap, nis and nisplus.

       -q, --quite
	      Don't be verbose.

       -u, --usage
	      Print a usage message and exit.

	   --help
	      Print a more verbose help text and exit.

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