CHFN(1) User Commands CHFN(1)
chfn - change your finger information
chfn [-f full-name] [-o office] ,RB [ -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.
chfn is used to change local entries only. Use ypchfn, lchfn or any other implementation
for non-local entries.
Any of the four pieces of information can be specified on the command line. If no infor-
mation 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.
