<title>DESCRIPTION</title>
<para>
The <command>chfn</command> command changes user fullname,
office room number, office phone number, 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>
These fields must not contain any colons. Except for the
<emphasis remap='I'>other</emphasis> field, they should not contain
any comma or equal sign. It is also recommended to avoid
non-US-ASCII characters, but this is only enforced for the phone
numbers. The <emphasis remap='I'>other</emphasis> field is used to
store accounting information used by other applications.
</para>
</refsect1>
<refsect1 id='options'>
<title>OPTIONS</title>
<para>
The options which apply to the <command>chfn</command> command are:
</para>

</variablelist>
<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.
