modinfo 描述

该modinfo命令从所给的Linux内核模块的命令提取信息的命令行。如果模块名称不是文件名，则搜索/ lib / modules / kernel-version目录-加载内核模块时，modprobe搜索相同的目录。

默认情况下，modinfo以以下形式列出模块的每个属性：

field name : value

模块文件名以相同的方式列出。

modinfo可以理解任何Linux内核体系结构的模块。

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 语法

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

modinfo -V

modinfo -h

选件

-V，-- version	打印modinfo的版本，然后退出。
-F，-- field field name	仅打印名为field name的字段的值。字段名称不区分大小写。公共字段名author，description，license，parm，depends和alias。对于给定的字段名称，通常有多个字段，例如parm，alias和depends。每行打印多个值。特殊字段名称file name列出了模块的文件名。
-k kernel	提供有关正在运行的内核以外的内核的信息。对于需要从新安装（但尚未运行）的内核模块集中提取信息的发行版，此开关特别有用。
-0，-- null	使用ASCII NULL 字符来分隔字段值，而不是换行符。此开关对于解析字段数据很有用，因为换行符可能是字段值的一部分。
-a，-d，-l，-p，-n	这些是用于显示字段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

显示有关snd Linux内核模块的所有可用信息。输出将类似于以下内容：

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

显示snd Linux内核模块的所有parm（参数）字段。输出将类似于以下内容（请注意，字段名称不为字段值加上前缀）：

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-*
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

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)
