前言：
眼前大家对“linux如何查看空间大小”都比较珍视，咱们都需要剖析一些“linux如何查看空间大小”的相关资讯。那么小编同时在网上收集了一些有关“linux如何查看空间大小””的相关知识，希望姐妹们能喜欢，朋友们一起来了解一下吧！1、内存
[root@localhost home]# cat /proc/meminfo | head -n 5MemTotal: 2035624 kB ## 总的内存大小MemFree: 824528 kBMemAvailable: 1221384 kBBuffers: 1780 kBCached: 496032 kB
[root@localhost home]# cat /proc/meminfo | head -n 1 | awk '{print $2/(1024 * 1024),"G"}'1.94132 G[root@localhost home]# free -h total used free shared buffers cachedMem: 1.9G 1.2G 782M 10M 1.7M 474M-/+ buffers/cache: 728M 1.2GSwap: 2.0G 0B 2.0G
2、硬盘
[root@localhost home]# df -hFilesystem Size Used Avail Use% Mounted on/dev/mapper/rhel-root 18G 3.0G 15G 17% /devtmpfs 985M 0 985M 0% /devtmpfs 994M 136K 994M 1% /dev/shmtmpfs 994M 8.8M 986M 1% /runtmpfs 994M 0 994M 0% /sys/fs/cgroup/dev/sda1 497M 119M 379M 24% /boot/dev/sr0 3.5G 3.5G 0 100% /media/cdrom
[root@localhost home]# fdisk -l |grep DiskDisk /dev/sda: 21.5 GB, 21474836480 bytes, 41943040 sectorsDisk label type: dosDisk identifier: 0x00094211Disk /dev/mapper/rhel-root: 18.8 GB, 18798870528 bytes, 36716544 sectorsDisk /dev/mapper/rhel-swap: 2147 MB, 2147483648 bytes, 4194304 sectors
3、cpu信息
[root@localhost home]# lscpuArchitecture: x86_64CPU op-mode(s): 32-bit, 64-bitByte Order: Little EndianCPU(s): 1On-line CPU(s) list: 0Thread(s) per core: 1Core(s) per socket: 1Socket(s): 1NUMA node(s): 1Vendor ID: AuthenticAMDCPU family: 23Model: 113Model name: AMD Ryzen 5 3600X 6-Core ProcessorStepping: 0CPU MHz: 3800.007BogoMIPS: 7600.01Virtualization: AMD-VHypervisor vendor: VMwareVirtualization type: fullL1d cache: 32KL1i cache: 32KL2 cache: 512KL3 cache: 32768KNUMA node0 CPU(s): 0
[root@localhost home]# cat /proc/cpuinfo | grep "physical id" | uniq | wc -l ## 查看物理CPU的个数1
[root@localhost home]# cat /proc/cpuinfo | grep "cpu cores" | uniq ## 物理cpu的核心数cpu cores : 1
[root@localhost home]# cat /proc/cpuinfo | grep 'model name' |uniq ## cpu的型号model name : AMD Ryzen 5 3600X 6-Core Processor
补充：物理cpu和逻辑cpu
root@PC1:/home/test# cat /proc/cpuinfo | grep 'model name' |uniq ## 查看cpu的型号model name : AMD Ryzen 5 3600X 6-Core Processor
root@PC1:/home/test# cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l ## 物理cpu的个数2
root@PC1:/home/test# cat /proc/cpuinfo| grep "cpu cores"| uniq ## 每个物理cpu中的核心数cpu cores : 4
root@PC1:/home/test# cat /proc/cpuinfo| grep "processor"| wc -l ##逻辑cpu的个数8
