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.
