Linux View hardware information for the system "go"

Linux View system hardware information, not as intuitive as windows, here I listed the view system information of the practical commands, and do a classification, examples of interpretation.

CPU

The LSCPU command, which looks at the CPU statistics.

[Email protected]:~$ lscpuarchitecture:          i686            #cpu架构CPU Op-mode (s):        32-bit, 64-bitbyte Order:            Little Endian   #小尾序CPU (s):                4               #总共有4 core  Thread Core * Core Socketon-line CPU (s) List:   0-3thread (s) per core:    1               #每个cpu核, only one thread is supported, that is, Hyper-threading core (s) per socket:    4               # For each CPU, there are 4 cores sockets (s):             1               #总共有1一个cpuVendor ID:             genuineintel    #cpu产商 intelcpu family:            6Model:                 42Stepping:              7CPU MHz:               1600.000BogoMIPS:              5986.12Virtualization:        vt-x            # Support for CPU Virtualization Technology L1D cache:             32kl1i cache:             32kl2 cache:              256kl3 cache:              6144K

View/proc/cpuinfo, you can know each CPU information, such as the model of each CPU, the frequency and so on.

#cat/proc/cpuinfoprocessor    : 0vendor_id    : Genuineintelcpu family    : 6model        : 42model name    : Intel ( R) Core (TM) i5-2320 CPU @ 3.00GHz .....

The above output is the first CPU part of the information, there are 3 of CPU information omitted.

Memory

Overview of Memory

The unit here is MB, and the total memory is 3926MB.

My motherboard has 4 slots, with only one slot, with a 4096MB of memory plugged in.
