RMMOD(8)							       rmmod								  RMMOD(8)

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. COPYRIGHT

MODINFO(8)							      modinfo								MODINFO(8)

NAME
modinfo - Show information about a Linux Kernel module SYNOPSIS
modinfo [-0] [-F field] [-k kernel] [modulename|filename...] modinfo -V modinfo -h DESCRIPTION
modinfo 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 modules. modinfo by default lists each attribute of the module in form fieldname : value, for easy reading. The filename is listed the same way (although it's not really an attribute). This version of modinfo can understand modules of any Linux Kernel architecture. OPTIONS
-V --version Print the modinfo version. -F --field 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. -k kernel 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. -0 --null 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. -a -d -l -p -n These are shortcuts for author, description, license. parm and filename respectively, to ease the transition from the old modutils modinfo.
