linux怎么查看硬盘型号等信息
3个回答
展开全部
1,查看CPU信息:cat /proc/cpuinfo
2,查看板卡信息:cat /proc/pci
3,查看USB设备:cat /proc/bus/usb/devices
4,查看PCI信息:lspci (相比cat /proc/pci更直观)
5,查看内存信息:cat /proc/meminfo
6,查看键盘和鼠标:cat /proc/bus/input/devices
7,查看系统硬盘信息和使用情况:fdisk & disk – l & df
8,用硬件检测程序kuduz探测新硬件:service kudzu start ( or restart)
9,查看各设备的中断请求(IRQ):cat /proc/interrupts
10,查看启动硬件检测信息日志:dmesg more /var/log/dmesguname -auptime
几种查看Linux版本信息的方法:
1: uname -a
2: cat /proc/version
3: cat /etc/issue
4: lsb_release -a
5:cat /etc/redhat-release
6:rpm -q redhat-release
详解 lsb_release -a
登录到服务器执行 lsb_release -a ,即可列出所有版本信息,例如:代码如下:
[hacder@NBCTC-14-15 ~]$ lsb_release -a
LSB Version: :core-3:1-amd64:core-3:1-ia32:core-3:1-noarch:graphics-3:1-amd64:graphics-3:1-ia32:graphics-3:1-noarch
Distributor ID: CentOS
Description: CentOS release 5:3 (Final)
Release: 5:3
Codename: Final
这个命令适用于所有的linux,包括Redhat、SuSE、Debian等发行版。
