NAME
       modinfo - 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, --field=field
	   Only print this field value, one per line. This is most useful for scripts.	Field  names  are  case-insensitive.
	   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.

       -b basedir, --basedir=basedir
	   Root directory for modules, / by default.

       -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 theoretically appear inside a field.

       -a --author, -d --description, -l --license, -p --parameters, -n --filename
	   These are shortcuts for the --field flag's author, description, license, parm and filename arguments, to ease the
	   transition from the old modutils modinfo.

       -h, --help
	   Print the help message and exit.
