NAME
       rmmod -- simple program to remove a module from the Linux Kernel

SYNOPSIS
       rmmod [-f]  [-w]  [-s]  [-v]  [modulename]

DESCRIPTION
       rmmod  is  a  trivial  program to remove a module (when module unloading support is provided) from the kernel.  Most users will want to use
       modprobe(8) with the -r option instead.

OPTIONS
       -v --verbose
		 Print messages about what the program is doing.  Usually rmmod prints messages only if something goes wrong.

       -f --force
		 This option can be extremely dangerous: it has no effect unless CONFIG_MODULE_FORCE_UNLOAD was set when the kernel was  compiled.
		 With  this  option,  you can remove modules which are being used, or which are not designed to be removed, or have been marked as
		 unsafe (see lsmod(8)).

       -w --wait Normally, rmmod will refuse to unload modules which are in use.  With this option, rmmod will isolate the module, and wait  until
		 the  module  is  no  longer  used.  Nothing new will be able to use the module, but it's up to you to make sure the current users
		 eventually finish with it.  See lsmod(8)) for information on usage counts.

       -s --syslog
		 Send errors to syslog instead of standard error.

       -V --version
		 Show version of program and exit.
