  <refsect1><title>DESCRIPTION</title>
    <para>
      <command>modinfo</command> extracts information from the Linux Kernel
      modules given on the command line.  If the module name is not a filename,
      then the
      <filename>@MODULE_DIRECTORY@/</filename><replaceable>version</replaceable>
      directory is searched, as is also done by
      <citerefentry><refentrytitle>modprobe</refentrytitle><manvolnum>8</manvolnum></citerefentry>
      when loading kernel modules.
    </para>
    <para>
      <command>modinfo</command> by default lists each attribute of the module
      in form <replaceable>fieldname</replaceable> :
      <replaceable>value</replaceable>, for easy reading.  The filename is
      listed the same way (although it's not really an attribute).
    </para>
    <para>
      This version of <command>modinfo</command> can understand modules of any
      Linux Kernel architecture.

          <para>
            Only print this field value, one per line.  This is most useful for
            scripts.  Field names are case-insensitive.  Common fields (which
            may not be in every module) include <literal>author</literal>,
            <literal>description</literal>, <literal>license</literal>,
            <literal>parm</literal>, <literal>depends</literal>, and
            <literal>alias</literal>.  There are often multiple
            <literal>parm</literal>, <literal>alias</literal> and
            <literal>depends</literal> fields.  The special field
            <literal>filename</literal> lists the filename of the module.

          <para>
            Provide information about a kernel other than the running one. This
            is particularly useful for distributions needing to extract
            information from a newly installed (but not yet running) set of
            kernel modules. For example, you wish to find which firmware files
            are needed by various modules in a new kernel for which you must
            make an initrd/initramfs image prior to booting.

        <listitem>
          <para>
            Use the ASCII zero character to separate field values, instead of a
            new line.  This is useful for scripts, since a new line can
            theoretically appear inside a field.
