Linux 查看硬件信息

1, 主板信息 .查看主板的序列号 -------------------------------------------------- #使用命令 dmidecode | grep -i 'serial number' #查看板卡信息 cat /proc/pci -------------------------------------------------- 2, cpu信息 -------------------------------------------------- #通过/proc文件系统 1) cat /proc/cpuinfo #通过查看开机信息 2) dmesg | grep -i 'cpu' # 3)dmidecode -t processor -------------------------------------------------- 3, 硬盘信息 -------------------------------------------------- #查看分区情况 fdisk -l #查看大小情况 df -h #查看使用情况 du -h # hdparm -I /dev/sda # dmesg | grep sda -------------------------------------------------- 4, 内存信息 -------------------------------------------------- 1) cat /proc/meminfo 2) dmesg | grep mem 3) free -m 4) vmstat 5) dmidecode | grep -i mem -------------------------------------------------- 5, 网卡信息 -------------------------------------------------- 1) dmesg | grep -i 'eth' 2) cat /etc/sysconfig/hwconf | grep -i eth 3) lspci | grep -i 'eth' -------------------------------------------------- 6, 鼠标键盘和USB信息 查看键盘和鼠标：cat /proc/bus/input/devices 查看USB设备：cat /proc/bus/usb/devices 查看各设备的中断请求(IRQ):cat /proc/interrupts 7, 显卡信息 -------------------------------------------------- 1)lspci |grep -i 'VGA' 2)dmesg | grep -i 'VGA' -------------------------------------------------- 8, 声卡信息 -------------------------------------------------- 1)lspci |grep -i 'VGA' 2)dmesg | grep -i 'VGA' -------------------------------------------------- 7, 其他命令 .用硬件检测程序kuduz探测新硬件：service kudzu start ( or restart) .dmesg (查看所有启动时检测到的硬件信息) .lspci (显示外设信息, 如usb，网卡等信息) .cat /etc/sysconfig/hwconf .mpstat 8, 需要手动安装的工具 lshw,hwinfo,hal-device-manager 9, Solaris如何检测硬件参数 俺从别处发现了些有意思的东西： Solaris的硬件相关命令 发表：2004-3-8 11:20:36 出处：你的博客网(yourblog.org) -------------------------------------------------------------------------------- 1)．查看当前处理器的类型和速度(主频) # psrinfo �Cv Status of processor 1 as of: 11/24/01 10:34:41 Processor has been on-line since 11/24/01 10:18:20.
