linux查看cpu核数和内存指令
# 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或grep 'physical id' /proc/cpuinfo | sort -u | wc -l# 查看每个物理CPU中core的个数(即核数)cat /proc/cpuinfo| grep "cpu cores"| uniq或者grep 'core id' /proc/cpuinfo | sort -u | wc -l# 查看逻辑CPU的个数cat /proc/cpuinfo| grep "processor"| wc -l或者grep 'processor' /proc/cpuinfo | sort -u | wc -l# 查看CPU信息（型号）cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c或者dmidecode -s processor-version#查看内 存信息cat /proc/meminfo```
