lchfn - Change finger information

       Displays  and  allows  changing  information  about  user  that  is available using the finger(1) command
       (usually stored in the "gecos" field of /etc/passwd).

       If the user argument is not provided, username of the invoking user is used; the user argument is ignored
       if lchfn is run set-uid to a different user.

       Entering an empty string (by pressing Enter) at a prompt is interpreted as accepting a default value;  to
       erase an attribute (or to use an empty string as the attribute value), enter a single dot character.

       The exit status is 0 on success, 1 on error.
