rmmod

rmmod is a trivial program to remove a module from the kernel. Most users will want to use modprobe instead, with the -r option.

Syntax

rmmod [PARAMETER ...] [MODULE]

Parameters

-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).

-s, --syslog

Send errors to syslog instead of standard error.

-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 for information on usage counts.
