| <title>DESCRIPTION</title> |
| |
| <para><command>rmmod</command> is a trivial program to remove a |
| module from the kernel. Most users will want to use |
| <citerefentry> |
| <refentrytitle>modprobe</refentrytitle><manvolnum>8</manvolnum> |
| </citerefentry> instead, with the <option>-r</option> option. |
| </para> |

| <title>OPTIONS</title> |
| <variablelist> |
| <varlistentry> |
| <term><option>-v</option> <option>--verbose</option> |
| </term> |
| <listitem> |
| <para> |
| Print messages about what the program is doing. |
| Usually <command>rmmod</command> only prints messages |
| if something goes wrong. |
| </para> |
| </listitem> |
| </varlistentry> |
| <varlistentry> |
| <term><option>-f</option> <option>--force</option> |
| </term> |
| <listitem> |
| <para> |
| 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 <citerefentry> |
| <refentrytitle>lsmod</refentrytitle><manvolnum>8</manvolnum> |
| </citerefentry>). |
| </para> |
| </listitem> |
| </varlistentry> |
| <varlistentry> |
| <term><option>-w</option> <option>--wait</option> |
| </term> |
| <listitem> |
| <para> |
| Normally, <command>rmmod</command> will refuse to |
| unload modules which are in use. With this option, |
| <command>rmmod</command> will isolate the module, and |
| wait until the module is no longer used. Noone 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 <citerefentry> |
| <refentrytitle>lsmod</refentrytitle><manvolnum>8</manvolnum> |
| </citerefentry>) for information on usage counts. |
| </para> |
| </listitem> |
| </varlistentry> |
| <varlistentry> |
| <term><option>-s</option> <option>--syslog</option> |
| </term> |
| <listitem> |
| <para> |
| Send errors to the syslog, instead of standard error. |
| </para> |
| </listitem> |
| </varlistentry> |
| <varlistentry> |
| <term><option>-V</option> <option>--version</option> |
| </term> |
| <listitem> |
| <para> |
| Show version of program, and exit. See below for caveats |
| when run on older kernels. |

| <title>BACKWARDS COMPATIBILITY</title> |
| |
| <para> |
| This version of <command>rmmod</command> is for kernels |
| <literal>2.5.48</literal> and above. If it detects a kernel |
| with support for old-style modules (for which much of the work |
| was done in userspace), it will attempt to run |
| <command>rmmod.old</command> in its place, so it is completely |
| transparent to the user. |
