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 from the kernel.	 Most
       users will want to use modprobe(8) instead, with the -r option.


OPTIONS
       -v --verbose
		 Print messages about what the	program	 is  doing.   Usually
		 rmmod only prints messages 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.  Noone 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 the syslog, instead of standard error.


       -V --version
		 Show version of program, and exit.  See  below	 for  caveats
		 when run on older kernels.


BACKWARDS COMPATIBILITY
       This  version of rmmod is for kernels 2.5.48 and above.	If it detects
       a kernel with support for old-style modules (for	 which	much  of  the
       work  was  done in userspace), it will attempt to run rmmod.old in its
       place, so it is completely transparent to the user.
