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.

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.
-b basedir, --basedir basedir
Root directory for modules, / by default.
-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 --author, -d --description, -l --license, -p --parameters, -n --filename
These are shortcuts for the --field flag's author, description, license, parm and filename arguments, to ease the transition from the
old modutils modinfo.
