.SH NAME
.PP
modinfo \- Show information about a Linux Kernel module
.PP
.SH SYNOPSIS
.PP
\fBmodinfo\fR [\fB\-0\fR] [\fB\-F\fR \fIfield\fR] [\fB\-k\fR \fIkernel\fR] [modulename|filename.\&.\&.\&]
.PP
\fBmodinfo\fR \fB\-V\fR
.PP
\fBmodinfo\fR \fB\-h\fR
.PP
.SH DESCRIPTION
.PP
\fBmodinfo\fR extracts information from the Linux Kernel modules given on the
command line.\& If the module name is not a filename, then the /lib/modules/
\fIversion\fR directory is searched, as is also done by \fBmodprobe\fR(8) when loading
kernel modules.\&
.PP
\fBmodinfo\fR by default lists each attribute of the module in form \fIfieldname\fR :
\fIvalue\fR, for easy reading.\& The filename is listed the same way (although it'\&s
not really an attribute).\&
.PP
This version of \fBmodinfo\fR can understand modules of any Linux Kernel
architecture.\&
.PP
.SH OPTIONS
.PP
\fB\-V\fR, \fB\-\-version\fR
.RS 4
Print the \fBmodinfo\fR version.\&
.PP
.RE
\fB\-F\fR \fIfield\fR, \fB\-\-field\fR=\fIfield\fR
.RS 4
Only print this \fIfield\fR 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 author, description, license, parm, depends,
and alias.\& There are often multiple parm, alias and depends fields.\& The
special \fIfield\fR filename lists the filename of the module.\&
.PP
.RE
\fB\-b\fR \fIbasedir\fR, \fB\-\-basedir\fR=\fIbasedir\fR
.RS 4
Root directory for modules, / by default.\&
.PP
.RE
\fB\-k\fR \fIkernel\fR
.RS 4
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.\&
.PP
.RE
\fB\-0\fR, \fB\-\-null\fR
.RS 4
Use the ASCII zero character to separate \fIfield\fR values, instead of a new
line.\& This is useful for scripts, since a new line can theoretically
appear inside a \fIfield\fR.\&
.PP
.RE
\fB\-a\fR \fB\-\-author\fR, \fB\-d\fR \fB\-\-description\fR, \fB\-l\fR \fB\-\-license\fR, \fB\-p\fR \fB\-\-parameters\fR, \fB\-n\fR \fB\-\-filename\fR
.RS 4
These are shortcuts for the \fB\-\-field\fR flag'\&s author, description,
license, parm and filename arguments, to ease the transition from the
old modutils \fBmodinfo\fR.\&
.PP
.RE
\fB\-h\fR, \fB\-\-help\fR
.RS 4
Print the help message and exit.\&
