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

rmmod [ -f ] [ -w ] [ -s ] [ -v ] [ \fBmodulename\fB ]

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.

• -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.
