chfn—changes the finger information

chfn  [ -f full-name ] [ -o office ] [ -poffice-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.
