硬件检测工具汇总

一、内核检测：
# dmesg 硬件及启动信息
# lsdev 已安装硬件
# dd if=/dev/meme bs=1k skip=768 count=256 2>/dev/null | strings -n 8  读bios

二、工具检测
Linux
# cat /proc/meminfo
# cat /proc/meminfo
# grep MemTotal /proc/meminfo
# watch -nl 'cat /proc/interrupts'
# free -m
# cat /proc/devices
# lspci -tv   PCI设备
# lsusb -tv  USB设备
# lshal
# dmidecode

FreeBSD
# sysctl hw.model  CPU类型
# sysctl hw  所有的硬件信息
# sysctl vm  内存使用情况
# dmesg | grep "real mem" 
# sysctl -a | grep mem
# sysctl dev
# pciconf -l -cv  PCI设备
# usbdevs -v      USB设备
# atacontrol list ATA设备
