This "Linux system how to view hard disk size and other hardware information" article, the article example code introduction is very detailed, with a certain reference value, interested friends must refer to, for the "Linux system how to view hard disk size and other hardware information", Xiaobian sorted out the following knowledge points, please follow the pace of Xiaobian step by step slowly understand, then let us enter the topic.

1. Linux CPU size

# cat / proc/cpuinfo | grep "model name" & & cat / proc/cpuinfo | grep "physical id" model name: Intel (R) Core (TM) i5-4460 CPU @ 3.20GHz physical id: 0123 description: you can see the details of each cpu in / proc/cpuinfo. But for dual-core cpu, you will see two cpu in cpuinfo. It is often mistaken for two single-core cpu. In fact, Physical Processor ID should be used to distinguish between single-core and dual-core. Physical Processor ID can be found in cpuinfo or dmesg. Flags if it has ht that supports hyper-threading technology to determine the number of physical CPU, you can check the value of physical id. The same physical CPU can be seen above. This machine has two dual-core CPU,ID of 0 and 3, and the size is 2.8G.

Second, memory size

[root@xbidc ~] # cat / proc/meminfo | grep MemTotal MemTotal: 1034612 kB [root@xbidc ~] # 123 3. Usage of qualified partitions of hard disk size

[root@xbidc ~] # fdisk-l | grep Disk Disk / dev/sda: 300.0 GB 300000000 bytes [root@xbidc ~] # df-h Filesystem Size Used Avail Use% Mounted on / dev/sda1 228G 80G 148G 27% / none 4.0K 04.0K 0% / sys/fs/cgroup udev 491M 4.0K 491m 1% / dev tmpfs 101m 1.4m 99m 2% / run none 5.0M 05.0M 0% / run/lock None 501m 152K 501m 1% / run/shm none 100m 44K 100m 1% / run/user1234567891011 4, More ways to view linux hardware information
