在LINUX环境开发驱动程序，首先要探测到新硬件，接下来就是开发驱动程序。常用命令整理如下：用硬件检测程序kuduz探测新硬件：service kudzu start ( or restart)查看CPU信息：cat /proc/cpuinfo processor 0 为一个U， 1为两个，flags超线程。查看板卡信息：cat /proc/pci查看PCI信息：lspci (相比cat /proc/pci更直观）查看内存信息：cat /proc/meminfo & free查看USB设备：cat /proc/bus/usb/devices查看键盘和鼠标:cat /proc/bus/input/devices查看系统硬盘信息和使用情况：fdisk & disk – l & df -h查看各设备的中断请求(IRQ):cat /proc/interrupts查看系统体系结构：uname -admidecode查看硬件信息，包括bios、cpu、内存等信息dmesg | more 查看硬件信息uptime 查运行时间 负载情况top 这个比较全，内存 进程 负载 都有了。cat /etc/redhat-release 看这个配置文件也可以。不过管理员可以修改这里的内容lsb_release -a 查看系统版本。－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－我的FC5显示结果如下：
