MODINFO(O)             Linux Module Support            MODINFO(O)



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  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.

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

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