<title>DESCRIPTION</title>
<para>
The <command>chfn</command> command changes user fullname,
office number, office extension, and home phone number information
for a user's account. This information is typically printed by
<citerefentry><refentrytitle>finger</refentrytitle><manvolnum>1</manvolnum>
</citerefentry> and similar programs. A normal user may only change
the fields for her own account, subject to the restrictions in
<filename>/etc/login.defs</filename>. (The default configuration is to
prevent users from changing their fullname.) The superuser may change
any field for any account. Additionally, only the superuser may use
the <option>-o</option> option to change the undefined portions of the
GECOS field.
</para>
<para>The only restriction placed on the contents of the fields is that
no control characters may be present, nor any of comma, colon, or
equal sign. The <emphasis remap='I'>other</emphasis> field does not
have this restriction, and is used to store accounting information
used by other applications.
</para>
<para> If none of the options are selected, <command>chfn</command>
operates in an interactive fashion, prompting the user with the
current values for all of the fields. Enter the new value to change
the field, or leave the line blank to use the current value. The
current value is displayed between a pair of <emphasis remap='B'>[
]</emphasis> marks. Without options, <command>chfn</command>
prompts for the current user account.
