# 总核数 = 物理CPU个数 X 每颗物理CPU的核数 
# 总逻辑CPU数 = 物理CPU个数 X 每颗物理CPU的核数 X 超线程数

# 查看物理CPU个数
cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l

# 查看每个物理CPU中core的个数(即核数)
cat /proc/cpuinfo| grep "cpu cores"| uniq

# 查看逻辑CPU的个数
cat /proc/cpuinfo| grep "processor"| wc -l

查看CPU信息(型号)
cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
 
查看内 存信息
# cat /proc/meminfo
