ubuntu 看硬件配置

总是忘记阿，标记一下

sudo lspci -v

lshw -C network

modprobe mac80211

--------------------------------------------------
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

#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

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

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

Processor has been on-line since 11/24/01 10:18:20.
The sparcv9 processor operates at 432 MHz,
and has a sparcv9 floating point processor.
Status of processor 3 as of: 11/24/01 10:34:41
Processor has been on-line since 11/24/01 10:18:22.
The sparcv9 processor operates at 432 MHz,
and has a sparcv9 floating point processor.
2)．打印当前的OBP版本号
# prtconf –V
