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(méi)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

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

[root@linuxprobe ~]# cat /proc/cpuinfo | grep "physical id" | uniq | wc -l
2 //cpu個(gè)數(shù)
[root@linuxprobe ~]# cat /proc/cpuinfo | grep "cpu cores" | uniq
cpu cores : 2 //線程數(shù)
