chfn (change finger) is a command on Unix-like systems that changes a user account's GECOS information, such as real name, office, and phone number. This information is stored in the fifth field of /etc/passwd and is displayed by commands such as finger. Regular users can change only their own information, while administrators can also change other users' information; on BSD systems it is another name for the same program as chpass and chsh.
chpass, chfn, chsh -- add or change user database information
