       lchfn - Change finger information

       lchfn [OPTION]... [user]

       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.

       -i, --interactive
	      Ask all questions when connecting to the user database, even if default answers are
	      set up in libuser configuration.

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