#Less proc cpuinfo full
There are also other tools that you can use to determine your CPU name and vendor such as dmidecode, hardinfo and lshw, but most of them are not installed by default on Linux systems.įeel free to leave a comment if you have any questions.For a start here is the full info on kernel options and processor details:
#Less proc cpuinfo how to
In this guide, we have shown you how to find information about your system CPU. Unlike the content of the /proc/cpuinfo file, the output of the lscpu doesn’t show a list of all logical CPUs.

The output will look something like below, including information about the number of CPUs, architecture, vendor, family, model, speed, caches, flags, etc. lscpu is a part of the util-linux package which is installed on all Linux distributions. Lscpu is a command line utility that displays information about the CPU architecture. Another way to find the number of CPUs is by using the nproc command: nproc 8
#Less proc cpuinfo software
Knowing the number of CPUs can be handy when you need to compile software from source and you want to know how many parallel processes can be concurrently executed. To print the number of CPUs: grep -c 'model name' /proc/cpuinfo 8 For example, to display only the processor name you would use: grep -m 1 'model name' /proc/cpuinfo model name : Intel(R) Core(TM) i5-8250U CPU 1.60GHz If you want to filter the output you can use the grep command. You can find a list of all features here. Once you know the exact type of CPU you are having, you can check the product documentation about the specifications of your processor. model name – The full name of the processor, including the processor brand.processor – A unique identifying number of each processor, starting from 0.Model name : Intel(R) Core(TM) i5-8250U CPU 1.60GHzįlags : 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 art arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc cpuid aperfmperf tsc_known_freq pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 sdbg fma cx16 xtpr pdcm pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm 3dnowprefetch cpuid_fault epb invpcid_single pti ssbd ibrs ibpb stibp tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid mpx rdseed adx smap clflushopt intel_pt xsaveopt xsavec xgetbv1 xsaves dtherm ida arat pln pts hwp hwp_notify hwp_act_window hwp_epp flush_l1dīugs : cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tfĪddress sizes : 39 bits physical, 48 bits virtualīelow is an explanation of the most interesting lines: Below is an example of the output: processor : 0 For example, if you have 8 core processor you will see a list of all cores starting from 0 to 7. The command will print each logical CPU with an identifying number. Open your terminal and use less or cat to display the contents of the /proc/cpuinfo: less /proc/cpuinfo It will work no matter what Linux distribution you are using. Identifying the type of processor using the proc/cpuinfo file does not require installing any additional programs. The simplest way to determine what type of CPU you have is by displaying the contents of the /proc/cpuinfo virtual file.
