kudzu 是Linux下检测硬件变化的命令，这个命令可以用于检查系统中网卡的型号等信息：

　　kudzu(1)

　　NAME

　　kudzu - detects and configures new and/or changed hardware on a system

　　SYNOPSIS

　　kudzu

　　DESCRIPTION

　　kudzu detects and configures new and/or changed hardware on a system.

　　When started, kudzu detects the current hardware, and checks it against

　　a database stored in /etc/sysconfig/hwconf, if one exists. It then

　　determines if any hardware has been added or removed from the system.

　　If so, it gives the users the opportunity to configure any added hard-

　　ware, and unconfigure any removed hardware. It then updates the

　　database in /etc/sysconfig/hwconf.

　　If no previous database exists, kudzu attempts to determine what

　　devices have already been configured, by looking at /etc/modules.conf,

　　/etc/sysconfig/network-scripts/, and /etc/X11/XF86Config.

　　以下是这个命令执行的输出示例：

　　[root@wapdbrac1 ~]# kudzu --probe --class=network
