modinfo 描述

該modinfo命令從所給的Linux內核模塊的命令提取信息的命令行。如果模塊名稱不是文件名，則搜索/ lib / modules / kernel-version目錄-加載內核模塊時，modprobe搜索相同的目錄。

默認情況下，modinfo以以下形式列出模塊的每個屬性：

field name : value

模塊文件名以相同的方式列出。

modinfo可以理解任何Linux內核體系結構的模塊。

The modinfo command extracts information from the Linux kernel modules given on the command line. If module name is not a file name, then the /lib/modules/kernel-version directory is searched — the same directory searched by modprobe when loading kernel modules.

By default, modinfo lists each attribute of the module in the form:

field name : value

The module file name is listed the same way.

modinfo can understand modules of any Linux Kernel architecture.

modinfo 語法

modinfo [-0] [-F field] [-k kernel] [module name|file name...]

modinfo -V

modinfo -h

選件

-V，-- version	打印modinfo的版本，然后退出。
-F，-- field field name	僅打印名為field name的字段的值。字段名稱不區分大小寫。公共字段名author，description，license，parm，depends和alias。對于給定的字段名稱，通常有多個字段，例如parm，alias和depends。每行打印多個值。特殊字段名稱file name列出了模塊的文件名。
-k kernel	提供有關正在運行的內核以外的內核的信息。對于需要從新安裝（但尚未運行）的內核模塊集中提取信息的發行版，此開關特別有用。
-0，-- null	使用ASCII NULL 字符來分隔字段值，而不是換行符。此開關對于解析字段數據很有用，因為換行符可能是字段值的一部分。
-a，-d，-l，-p，-n	這些是用于顯示字段author，description，license，parm和file name的快捷方式。

modinfo [-0] [-F field] [-k kernel] [module name|file name...]

modinfo -V

modinfo -h

Options

-V, --version	Print the version of modinfo, and exit.
-F, --field field name	Only print the value of the field named field name. Field names are case-insensitive. Common field names are author, description, license, parm, depends, and alias. There are often multiple fields for a given field name, for instance parm, alias, and depends. Multiple values are printed one per line. The special field name, file name, lists the file name of the module.
-k kernel	Provide information about a kernel other than the running one. This switch is particularly useful for distributions needing to extract information from a newly-installed (but not yet running) set of kernel modules.
-0, --null	Use the ASCII NULL character to separate field values, instead of a newline. This switch is useful for parsing field data, because a newline might be part of a field's value.
-a, -d, -l, -p, -n	These are shortcuts for displaying the fields author, description, license, parm, and file name.

modinfo 例子

modinfo snd

顯示有關snd Linux內核模塊的所有可用信息。輸出將類似于以下內容：

file name:       /lib/modules/3.2.0-4-686-pae/kernel/sound/core/snd.ko
alias:          char-major-116-*
license:        GPL
description:    Advanced Linux Sound Architecture driver for sound cards.
author:         Jaroslav Kysela 
license:        GPL
description:    Jack detection support for ALSA
author:         Mark Brown 
depends:        soundcore
intree:         Y
vermagic:       3.2.0-4-686-pae SMP mod_unload modversions 686 
parm:           slots:Module names assigned to the slots. (array of charp)
parm:           major:Major # for sound driver. (int)
parm:           cards_limit:Count of auto-loadable sound cards. (int)

modinfo -F parm snd

顯示snd Linux內核模塊的所有parm（參數）字段。輸出將類似于以下內容（請注意，字段名稱不為字段值加上前綴）：

slots:Module names assigned to the slots. (array of charp)
major:Major # for sound driver. (int)
cards_limit:Count of auto-loadable sound cards. (int)

modinfo snd

Display all available information about the snd Linux kernel module. Output will resemble the following:

file name:       /lib/modules/3.2.0-4-686-pae/kernel/sound/core/snd.ko
alias:          char-major-116-*

depends:        soundcore
intree:         Y
vermagic:       3.2.0-4-686-pae SMP mod_unload modversions 686 
parm:           slots:Module names assigned to the slots. (array of charp)
parm:           major:Major # for sound driver. (int)
parm:           cards_limit:Count of auto-loadable sound cards. (int)

modinfo -F parm snd

Display all parm (parameter) fields for the snd Linux kernel module. Output will resemble the following (Note that the field name does not prefix the field values):

slots:Module names assigned to the slots. (array of charp)
major:Major # for sound driver. (int)
cards_limit:Count of auto-loadable sound cards. (int)
