      linux怎么查看cpu個(gè)數(shù)

        關(guān)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(gè)數(shù)?下面是學(xué)習(xí)啦小編為你整理相關(guān)的內(nèi)容,希望大家喜歡!

        linux查看cpu個(gè)數(shù)

        談到系統(tǒng)版本就一定會(huì)想到uname,查看系統(tǒng)內(nèi)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(shí)看到了許多信息,但是好像并不是我想要的,沒有哪個(gè)系統(tǒng)的哪個(gè)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)

        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

        查看內(nèi)存相關(guān)

        free

        一談到Linux的內(nèi)存就想到了一個(gè)命令free,在課本第2章 新手必須掌握的Linux命令中有對(duì)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(nèi)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
