Ubuntu16下查看CPU、内存和磁盘相关信息

1.内存

查看内存
#free -m
              total        used        free      shared  buff/cache   available
Mem:          96685         986       94887          25         811       94802
Swap:         98300           0       98300

2.CPU

查看逻辑cpu个数:5
#cat /proc/cpuinfo | grep "processor" | wc -l
5


查看物理 cpu个数:1
#cat /proc/cpuinfo | grep "physical id" | sort | uniq | wc -l
1

#cat /proc/cpuinfo | grep physical | uniq -c
      1 physical id    : 0
      1 address sizes    : 42 bits physical, 48 bits virtual
      1 physical id    : 0
      1 address sizes    : 42 bits physical, 48 bits virtual
      1 physical id    : 0
      1 address sizes    : 42 bits physical, 48 bits virtual
      1 physical id    : 0
      1 address sizes    : 42 bits physical, 48 bits virtual
      1 physical id    : 0
      1 address sizes    : 42 bits physical, 48 bits virtual


查看cpu cores核数:5

#cat /proc/cpuinfo | grep "cpu cores" | wc -l
5

查看cpu 主频、型号: 2.3GHz
#cat /proc/cpuinfo | grep name |cut -f2 -d: | uniq -c
      5  Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz

3.磁盘大小

查看磁盘空间大小
sudo fdisk -l | grep "Disk /dev/sda"
#Disk /dev/sda: 900 GiB, 966367641600 bytes, 1887436800 sectors
