DESCRIPTION
       modprobe intelligently adds or removes a module from the Linux  kernel:  note  that
       for  convenience, there is no difference between _ and - in module names.  modprobe
       looks in the module directory /lib/modules/'uname -r' for all the modules and other
       files,  except for the optional /etc/modprobe.conf configuration file and /etc/mod-
       probe.d directory (see modprobe.conf(5)). modprobe will  also  use  module  options
       specified on the kernel command line in the form of <module>.<option>.

       Note  that  this version of modprobe does not do anything to the module itself: the
       work of resolving symbols and understanding parameters is done inside  the  kernel.
       So module failure is sometimes accompanied by a kernel message: see dmesg(8).

       modprobe  expects  an up-to-date modules.dep file, as generated by depmod (see dep-
       mod(8)). This file lists what other modules each module needs (if  any),  and  mod-
       probe  uses  this  to  add  or  remove  these  dependencies automatically. See mod-
       ules.dep(5)).

       If any arguments are given after the modulename, they are passed to the kernel  (in
       addition to any options listed in the configuration file).

OPTIONS
       -v --verbose
              Print messages about what the program is doing. Usually modprobe only prints
              messages if something goes wrong.

              This option is passed through install or remove commands to  other  modprobe
              commands in the MODPROBE_OPTIONS environment variable.

       -C --config
              This  option  overrides  the default configuration directory/file (/etc/mod-
              probe.d or /etc/modprobe.conf).

              This option is passed through install or remove commands to  other  modprobe
              commands in the MODPROBE_OPTIONS environment variable.

       -c --showconfig
              Dump out the effective configuration from the config directory and exit.

       -n --dry-run
              This  option  does  everything but actually insert or delete the modules (or
              run the install or remove commands). Combined with  -v,  it  is  useful  for
              debugging problems.

       -i --ignore-install --ignore-remove
              This  option  causes  modprobe  to ignore install and remove commands in the
              configuration file (if any) for the module specified  on  the  command  line
              (any  dependent  modules  are  still subject to commands set for them in the
              configuration file).  See modprobe.conf(5).

       -q --quiet
              Normally modprobe will report an error if you try to remove or insert a mod-
              ule  it can't find (and isn't an alias or install/remove command). With this
              flag, modprobe will simply ignore any bogus names (the kernel uses  this  to
              opportunistically probe for modules which might exist).

       -r --remove
              This  option  causes  modprobe to remove rather than insert a module. If the
              modules it depends on are also unused, modprobe will try to remove them too.
              Unlike  insertion, more than one module can be specified on the command line
              (it does not make sense to specify module parameters when removing modules).

              There is usually no reason to remove modules, but some buggy modules require
              it. Your kernel may not support removal of modules.

       -w --wait
              This option is applicable only with the -r or --remove  option.   It  causes
              modprobe  to  block  in  the  kernel (within the kernel module handling code
              itself) waiting for the specified module's reference count  to  reach  zero.
              Default  operation  is  for modprobe to operate like rmmod, which exits with
              EWOULDBLOCK if the module's reference count is non-zero.

       -V --version
              Show version of program and exit.

       -f --force
              Try to strip any versioning information from the module which  might  other-
              wise  stop  it from loading: this is the same as using both --force-vermagic
              and --force-modversion. Naturally, these checks are there for  your  protec-
              tion, so using this option is dangerous.

              This applies to any modules inserted: both the module (or alias) on the com-
              mand line and any modules it on which it depends.

       --force-vermagic
              Every module contains a small string containing important information,  such
              as  the kernel and compiler versions. If a module fails to load and the ker-
              nel complains that the "version magic"  doesn't  match,  you  can  use  this
              option  to remove it. Naturally, this check is there for your protection, so
              this using option is dangerous.

              This applies to any modules inserted: both the module (or alias) on the com-
              mand line and any modules on which it depends.

       --force-modversion
              When  modules  are compiled with CONFIG_MODVERSIONS set, a section detailing
              the versions of every interfaced used by (or supplied by) the module is cre-
              ated.  If  a  module  fails to load and the kernel complains that the module
              disagrees about a version of some interface, you  can  use  "--force-modver-
              sion" to remove the version information altogether. Naturally, this check is
              there for your protection, so using this option is dangerous.

              This applies any modules inserted: both the module (or alias) on the command
              line and any modules on which it depends.

       -l --list
              List  all  modules  matching  the  given  wildcard (or "*" if no wildcard is
              given). This option is provided for backwards compatibility: see find(1) and
              basename(1) for a more flexible alternative.

       -a --all
              Insert all module names on the command line.

       -t --type
              Restrict  -l  to  modules  in  directories  matching the dirname given. This
              option is provided for backwards compatibility: see find(1) and  basename(1)
              for a more flexible alternative.

       -s --syslog
              This option causes any error messages to go through the syslog mechanism (as
              LOG_DAEMON with level LOG_NOTICE) rather than to  standard  error.  This  is
              also automatically enabled when stderr is unavailable.

              This  option  is passed through install or remove commands to other modprobe
              commands in the MODPROBE_OPTIONS environment variable.

       -S --set-version
              Set the kernel version, rather than using uname(2) to decide on  the  kernel
              version (which dictates where to find the modules).

       -D --show-depends
              List  the  dependencies of a module (or alias), including the module itself.
              This produces a (possibly empty) set of module filenames, one per line, each
              starting  with  "insmod". Install commands which apply are shown prefixed by
              "install". It does not run any of the install commands. Note that modinfo(8)
              can  be used to extract dependencies of a module from the module itself, but
              knows nothing of aliases or install commands.

       -o --name
              This option tries to rename the module which is being inserted into the ker-
              nel.  Some  testing modules can usefully be inserted multiple times, but the
              kernel refuses to have two modules  of  the  same  name.  Normally,  modules
              should  not  require multiple insertions, as that would make them useless if
              there were no module support.

       --first-time
              Normally, modprobe will succeed (and do nothing) if told to insert a  module
              which  is already present or to remove a module which isn't present. This is
              ideal for simple scripts; however, more complicated scripts  often  want  to
              know  whether modprobe really did something: this option makes modprobe fail
              for that case.

       --dump-modversions
              Print out a list of module versioning information required by a module. This
              option is commonly used by distributions in order to package up a Linux ker-
              nel module using module versioning deps.

       -b --use-blacklist
              This option causes modprobe to apply the blacklist commands in the  configu-
              ration  files  (if  any)  to  module  names  as  well. It is usually used by
              udev(7).

       -d --dirname
              Directory where modules can be found, /lib/modules/RELEASE by default.

ENVIRONMENT
       The MODPROBE_OPTIONS environment variable can also be used  to  pass  arguments  to
       modprobe.
