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.

NAME

       modinfo - program to show information about a Linux Kernel module

SYNOPSIS

       modinfo [ -0 ]  [ -F field ]  [ -k kernel ]  [ modulename|filename... ]

       modinfo -V

       modinfo -h

DESCRIPTION

       modinfo	extracts  information  from  the  Linux  Kernel  modules given on the command line. If the module name is not a filename, then the
       /lib/modules/version directory is searched, as is also done by modprobe(8) when loading kernel modules.

       modinfo by default lists each attribute of the module in form fieldname : value, for easy reading. The filename	is  listed  the  same  way
       (although it's not really an attribute).

       This version of modinfo can understand modules of any Linux Kernel architecture.

OPTIONS

       -V --version
	      Print the modinfo version.

       -F --field
	      Only  print  this field value, one per line. This is most useful for scripts. Field names are case-insenitive.  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 field filename lists the filename of the module.

       -k kernel
	      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.

       -0 --null
	      Use the ASCII zero character to separate field values, instead of a new line. This is useful for scripts, since a new line can theo-
	      retically appear inside a field.

       -a -d -l -p -n
	      These are shortcuts for author, description, license. parm and filename respectively, to ease the transition from the  old  modutils
	      modinfo.
