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.
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.
