Show information about a Linux Kernel module
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

fieldname : value, for easy reading. The
filename is listed the same way (although it's not really an

Print the modinfo version.
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.

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 the
−−field flag's author, description,
license, parm and filename arguments, to ease the transition
from the old modutils modinfo.
