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.

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.
