.SH NAME
lchfn \- Change finger information

.SH SYNOPSIS
lchfn [\fIOPTION\fR]... [\fIuser\fR]

.SH DESCRIPTION
Displays and allows changing information about \fIuser\fR 
that is available using the
.BR finger (1)
command (usually stored in the "gecos" field of \fI/etc/passwd\fR).

If the \fIuser\fR argument is not provided,
username of the invoking user is used;
the \fIuser\fR argument is ignored if
.B 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.

.SH OPTIONS

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

.SH EXIT STATUS
The exit status is 0 on success, 1 on error.
