modinfo - display information about a kernel module
SYNOPSIS
modinfo [ options ] <module_file>
DESCRIPTION
The modinfo utility examines the object file module_file
associated with a kernel module and displays any informa
tion that it can glean.
OPTIONS
-a, --author
Display the module's author.
-d, --description
Display the module's description.
-fformat_string, --format format_string
Let the user specify an arbitrary format string
which can extract values from the ELF section in
module_file which contains the module information.
Replacements consist of a percent sign followed by
a tag name in curly braces. A tagname of %{file
name} is always supported, even if the module has
no modinfo section. %{kernel_version} shows the
version of the kernel the module was compiled for.
%{using_checksums} expands to 1 is the module has
versioned symbols and to 0 or <none> otherwise.
A tagname of %{parm} is special: the format string
line is repeated for each known module parameter
(which may be zero times) and %{parm} is then
replaced by descriptions of module parameters (one
parameter on each repeated line).
Alternatively, %a, %d, %l, %n and %p can be used
instead of %{author}, %{description}, %{filename},
%{license} and %{parm}, respectively.
-h, --help
Display a summary of options and immediately exit.
-l, --license
Display the module's license.
-n, --filename
Display the module's filename.
-p, --parameters
Display the typed parameters that a module may sup
port.
Display the version of modinfo.
If no options are supplied, the default is filename,
description, author, license and parameters.
