1.查看CPU逻辑id
grep 'physical id' /proc/cpuinfo | sort -u
physical id : 0
physical id : 1
2.查看物理CPU个数
$ cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l
2
3.查看每个物理CPU中core的个数
$ cat /proc/cpuinfo| grep "cpu cores"| uniq
cpu cores : 10
4.查看逻辑CPU的个数
$ cat /proc/cpuinfo| grep "processor"| wc -l
40
5.查看总线程数量
$ grep 'processor' /proc/cpuinfo | sort -u | wc -l
40
6.查看CPU信息（型号）
$ cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
40 Intel(R) Xeon(R) CPU E5-2640 v4 @ 2.40GHz
