modinfo - program to show information about a Linux Kernel module
modinfo [ -0 ] [ -F field ] [ -k kernel ] [ modulename|filename... ]
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
Print the modinfo version.
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.
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.
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.

These are shortcuts for author, description, license. parm and
