# kldstat.8

`kldstat` — 显示动态内核链接器状态

## 名称

`kldstat`

## 概要

`kldstat [-h] [-q] [-v] [-d] [-i id] [-n filename]`

`kldstat [-q] [-d] [-m modname]`

## 描述

`kldstat` 工具显示动态链接到内核的任何文件的状态。

可用选项如下：

**`-d`** 显示模块特定数据（以 int、unsigned int 和 unsigned long 形式）

**`-h`** 以人类可读的形式显示 size 字段，使用单位后缀代替十六进制值。

**`-i`** `id` 仅显示具有此 ID 的文件的状态。

**`-m`** `modname` 仅显示具有此 modname 的模块的状态。

**`-n`** `filename` 仅显示具有此 filename 的文件的状态。

**`-q`** 静默检查文件是否已加载或编译进内核。

**`-v`** 显示更详细的信息。

## 退出状态

`kldstat` 工具成功时退出值为 0，发生错误时大于 0。

## 实例

显示动态链接到内核的文件。注意内核本身也显示在列表中。*Refs* 显示每个文件引用的模块数量：

```sh
$ kldstat
Id Refs Address                Size Name
 1   38 0xffffffff80200000  2448f20 kernel
 2    3 0xffffffff82649000    b7bd8 linux.ko
 3    5 0xffffffff82701000     9698 linux_common.ko
 4    1 0xffffffff82b11000     1eae linsysfs.ko
 5    1 0xffffffff82b13000    f2af8 nvidia-modeset.ko
 6    1 0xffffffff82c06000  122b020 nvidia.ko
 7    1 0xffffffff83e32000     2668 intpm.ko
 8    1 0xffffffff83e35000      b50 smbus.ko
 9    1 0xffffffff83e36000     18a0 uhid.ko
10    1 0xffffffff83e38000     2928 ums.ko
11    1 0xffffffff83e3b000     1aa0 wmt.ko
12    1 0xffffffff83e3d000     cd70 snd_uaudio.ko
```

显示 *linux* 文件的详细状态，并以人类可读的方式显示大小：

```sh
$ kldstat -h -v -n linux
Id Refs Address             Size Name
 2    3 0xffffffff82649000  735K linux.ko (/boot/kernel/linux.ko)
        Contains modules:
                 Id Name
                  2 linuxelf
```

同上，但使用文件的 *id*：

```sh
$ kldstat -h -i 2 -v
Id Refs Address             Size Name
 2    3 0xffffffff82649000  735K linux.ko (/boot/kernel/linux.ko)
        Contains modules:
                 Id Name
                  2 linuxelf
```

显示上例中获得的 *linuxelf* 模块的状态：

```sh
$ kldstat -v -m linuxelf
Id  Refs Name
  2    1 linuxelf
```

显示 *g\_raid* 模块的模块特定数据：

```sh
$ kldstat -d -m g_raid
Id  Refs Name data..(int, uint, ulong)
366    1 g_raid (0, 0, 0x0)
```

检查模块 *fakefile* 是否已链接。如果是则返回 0，否则返回 1：

```sh
$ kldstat -q -n fakefile || echo file not linked
file not linked
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man8/kldstat.8.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
