linux查看cpu個數，線程數及cpu型號

1.查看CPU邏輯id

grep 'physical id' /proc/cpuinfo | sort -u

physical id : 0
physical id : 1

2.查看物理CPU個數

$ cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l

2

3.查看每個物理CPU中core的個數

$ cat /proc/cpuinfo| grep "cpu cores"| uniq

cpu cores : 10

4.查看邏輯CPU的個數

$ cat /proc/cpuinfo| grep "processor"| wc -l

40

5.查看總線程數量

$ grep 'processor' /proc/cpuinfo | sort -u | wc -l

40

6.查看CPU信息（型號）

$ cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c

40  Intel(R) Xeon(R) CPU E5-2640 v4 @ 2.40GHz
