|
|
<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>/lib/modules/</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.

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.

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.

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.
