Product: Intel(R) Core(TM) i5-4210U CPU 1.70GHz To display complete CPU information, including per CPU clock-speed and CPU max speed (if available), use the -C flag as follows: $ inxi -C $ sudo yum install inxi #RHEL/CentOS systems You can install like so: $ sudo apt install inxi #Debian/Ubuntu systems You can use it to instantly retrieve hardware information. Inxi is a powerful command-line system information script intended for both console and IRC (Internet Relay Chat). Inxi Tool – Shows Linux System Information Signature: Type 0, Family 6, Model 69, Stepping 1ĥ. Shows Linux Hardware Information # dmidecode 3.0 The SMBIOS specification defines various DMI types, for CPU, use “processor” as follows: $ sudo dmidecode -type processor It dumps a computer’s DMI (a.k.a SMBIOS) table contents in a human-readable format for easy retrieval. dmidecode Command – Shows Linux Hardware Infoĭmidecode is a tool for retrieving hardware information of any Linux system.

$ sudo yum install cpuid #RHEL/CentOS systems $ sudo apt install cpuid #Debian/Ubuntu systems Make sure to install it before running it. The command cpuid dumps complete information about the CPU(s) collected from the CPUID instruction, and also discover the exact model of x86 CPU(s) from that information.

I am running Ubuntu and I don't understand why it's so hard for me to get the number of cores on my system in C! I've tried parsing /proc/cpuinfo with success on my system running Ubuntu but then I tried on another system running arch linux which would fail because the buffer was too small, and I can't seem to figure out how to make it work on both of my systems.Model name : Intel(R) Core(TM) i5-4210U CPU 1.70GHzįlags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 sdbg fma cx16 xtpr pdcm pcid sse4_1 sse4_2 movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm epb tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid xsaveopt dtherm ida arat pln ptsĪddress sizes : 39 bits physical, 48 bits virtual
