linuxcpu核数查看
Ⅰ linux如何查看cpu核心数和内存大小
linux查看cpu核数和内存大罩御高小命令分别为：
1、查看CPU个数*核心数：
cat /proc/cpuinfo |grep“physical id” | uniq | wc -l
96 #一共96核
2、查看内存总数
#cat /proc/meminfo | grep MemTotal
MemTotal: 230993600 kB
Linux下查看CPU型号,内存大小,硬盘空间的命令：
1、查看CPU核数
cat /proc/cpuinfo | grep “cpu cores” | uniq
cpu cores : 12 #12是拆虚单颗CPU的核心数
2、查看CPU型号
cat /proc/cpuinfo | grep ‘model name’ |uniq
model name : Intel® Xeon® CPU E7-4830 v3 @ 2.10GHz
3、查看linux物理内存数量物尺及大小
dmidecode -t memory | grep Size: | grep -v “No Mole Installed”
