modinfo(8)                                                          modinfo(8)




NAME

       modinfo — program to show information about a Linux Kernel module


SYNOPSIS

       modinfo [-0]  [-F field]  [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/mod-
       ules/version       directory is searched, as done by modprobe(8).


       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.   Note  BACKWARDS  COMPATIBILITY
                 below: you might be printing the version of modinfo.old.


       -F --field
                 Only print this field value, one per line.  This is most use-
                 ful for scripts.  Field names  are  case-insenitive.   Common
                 fields  (which  may  not  be in every module) include author,
                 description, license, param, depends, and alias.   There  are
                 often  multiple  param,  alias and depends       fields.  The
                 special field filename        lists the filename of the  mod-
                 ule.


       -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 theoretically appear inside a field.


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



BACKWARDS COMPATIBILITY

       This  version of modinfo is for kernel modules 2.5.48 and above.  If it
       detects a kernel with support for old-style modules, it will attempt to
       run  modprobe.old  in its place, so it is completely transparent to the
       user.

       Note that the output of this version of modinfo  is  simpler  and  more
       regular  than  the older version: scripts attempting to use the default
       output may get confused with complex fields.


       You can force the new  modinfo  to  always  be  used,  by  setting  the
       NEW_MODINFO   environment variable.
