NAME

       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 information 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 mod-
	      ule information.	Replacements consist of a percent sign followed by a tag name in curly braces.	A tagname of %{filename} 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}, respec-
	      tively.

       -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 support.

       -V, --version
	      Display the version of modinfo.

       If no options are supplied, the default is filename, description, author, license and parameters.
