Linux modprobe命令|极客笔记

Linux modprobe命令：在内核中添加和删除模块。

Linux modprobe命令功能描述

使用modprobe命令可以显示内核中的模块、查看模块的配置文件、加载模块及卸载模块。modprobe可加载指定的个别模块，或者是加载一组有依赖关系的模块。modprobe会根据depmod所产生的依赖关系，决定要加载哪些模块。如果在加载过程中发生错误，modprobe会卸载整组的模块。

Linux modprobe命令语法

modprobe [选项] [模块名]

命令中各选项的含义如表所示。

查看模块的配置文件，比如模块的别名等信息

[root@rhel ～]# modprobe -c
# Module options and blacklists written by anaconda
#
# Listing a module here prevents the hotplug scripts from loading it.
# Usually that'd be so that some other driver will bind it instead,
#no matter which driver happens to get probed first. Sometimes user
# mode tools can also control driver binding.
#
# Syntax: see modprobe.conf(5).
