    linux怎么查看cpu個數(shù)

      關于筆記本電腦的硬件參數(shù) ,我們要怎么在linux怎么查看cpu個數(shù)?下面是學習啦小編為你整理相關的內容,希望大家喜歡!

      linux查看cpu個數(shù)

      談到系統(tǒng)版本就一定會想到uname,查看系統(tǒng)內核版本

      uname -參數(shù)

      其他的什么-n -m -r 參數(shù)都忽略,直接-a

      [root@linuxprobe ~]#uname -a

      Linux linuxprobe.com 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux

      [root@linuxprobe ~]#

      從uname中貌似確實看到了許多信息,但是好像并不是我想要的,沒有哪個系統(tǒng)的哪個版本

      lsb_release -a

      [root@linuxprobe ~]# lsb_release -a

      LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch

      Distributor ID: RedHatEnterpriseServer

      Description: Red Hat Enterprise Linux Server release 6.4 (Santiago)

      Release: 6.4

      Codename: Santiago

      [root@linuxprobe ~]#

      cat /etc/issue

      [root@linuxprobe ~]#cat /etc/issueRed Hat Enterprise Linux Server release 6.4 (Santiago)Kernel \r on an \m

      [root@linuxprobe ~]#

      查看內存相關

      free

      一談到Linux的內存就想到了一個命令free,在課本第2章 新手必須掌握的Linux命令中有對此的解釋

      [root@linuxprobe ~]# free total used free shared buffers cachedMem: 5228872 669360 4559512 0 28060 266936

      -/+ buffers/cache: 374364 4854508

      Swap: 4194296 0 4194296

      [root@linuxprobe ~]# free -m

      total used free shared buffers cached

      Mem: 5106 653 4452 0 27 260

      -/+ buffers/cache: 365 4740

      Swap: 4095 0 4095

      [root@linuxprobe ~]# free -g

      total used free shared buffers cached

      Mem: 4 0 4 0 0 0

      -/+ buffers/cache: 0 4

      Swap: 3 0 3

      [root@linuxprobe ~]#

      很明顯內存大小,使用多少,剩余多少,buffers和cached多少,以及swap情況一目了然,使用參數(shù)-m/-g 可以指定單位

      cpu內存實時利用率以此為標準

      查看cpu參數(shù)——文件 :/proc/cpuinfo

      [root@linuxprobe ~]# cat /proc/cpuinfo | grep "physical id" | uniq | wc -l

      2 //cpu個數(shù)

      [root@linuxprobe ~]# cat /proc/cpuinfo | grep "cpu cores" | uniq

      cpu cores : 2 //線程數(shù)

      [root@linuxprobe ~]# cat /proc/cpuinfo | grep 'model name' |uniq

      model name : Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz //cpu型號參數(shù)
