less pages text files like more, but also lets you page up and down through them (press. It waits for a keystroke between each page. Updated my answer (and confirmed that it works both ways). It should work if you just change the command passed to popen (3), since both commands have the same output. more displays text files like cat, but pages them to the screen. Linus at 11:47 Linus Ah yeah, absolutely You can definitely use nproc (1) in place of grep + wc. cat /proc/cpuinfo could be less /proc/cpuinfo) more - usage. It can be read/written and can control the scaling policy. cat is used often below, but could easily be replaced by more or less (eg. That is controlled by the scaling_governor file. Some systems can throttle cpus based on workload/demand. It does not follow Arm’s new lower case logo / name, but who cares We can see most of the information provided by /proc/cpuinfo and more, but the BogoMIPS number is different, and the last three lines with Hardware, Revision and Serial are not shown. On my system, doing head -10 * in the cpu0/cpufreq directory produces: => affected_cpus bios_limit cpuinfo_cur_freq cpuinfo_max_freq cpuinfo_min_freq cpuinfo_transition_latency freqdomain_cpus related_cpus scaling_available_frequencies scaling_available_governors scaling_cur_freq scaling_driver scaling_governor scaling_max_freq scaling_min_freq scaling_setspeed It works as ARM Cortex-A7 revision 5 is shown. Now we will utilize the ‘grep’ and ‘cat’ command to only extract the information about the CPU speed from this file. cpufreq/policyN, so you may need to explore further for the particulars of your given kernel version. The /proc/cpuinfo file has all content related to the individual CPU cores. Instead of using grep, you can also use the less command for the same execution purpose. Now we will utilize the ‘grep’ and ‘cat’ command to only extract the information about the CPU speed from this file. By using cat, more, or less commands in combination with the files within /proc, you can immediately access an enormous amount of. In particular, cpuinfo_max_freq is the one you want to look at. The /proc/cpuinfo file has all content related to the individual CPU cores. A logical CPU can be a hyperthreading sibling, a shared core in a dual or quad core, or a separate physical CPU. In that directory there are many interesting files: affected_cpus Cygwin detects/displays less flags than Linux: flags : fpu vme de pse tsc msr mce cx8 pge mmx. The kernel data Linux exposes in /proc/cpuinfo will show each logical CPU with a unique processor number. N), look at the /sys/devices/system/cpu/cpuN/cpufreq directory. cat /proc/cpuinfo displays various information about your CPU. Model name: Intel(R) Core(TM) i9-9980XE CPU 3.Under linux, for a given CPU (e.g. The output of lscpu: Architecture: x86_64 Model name : Intel(R) Core(TM) i9-9980XE CPU 3.00GHzįlags : 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 pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 sdbg fma cx16 xtpr pdcm pcid dca sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm 3dnowprefetch cpuid_fault cat_l3 cdp_l3 invpcid_single pti ssbd mba ibrs ibpb stibp tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 hle avx2 smep bmi2 erms invpcid rtm cqm mpx rdt_a avx512f avx512dq rdseed adx smap clflushopt clwb intel_pt avx512cd avx512bw avx512vl xsaveopt xsavec xgetbv1 xsaves cqm_llc cqm_occup_llc cqm_mbm_total cqm_mbm_local dtherm ida arat pln pts hwp hwp_act_window hwp_pkg_req md_clear flush_l1dīugs : cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tf mdsĪddress sizes : 46 bits physical, 48 bits virtual He wrote more than 7k+ posts and helped numerous readers to master IT topics. Here is the part of content in cpuinfo: processor : 0 less /proc/cpuinfo About the author: Vivek Gite is the founder of nixCraft, the oldest running blog about Linux and open source. Steps: Read the file /proc/cpuinfo till you find the line with cpu cores in string. But it shows that the CPU has only 15 cores in /proc/cpuinfo as well as in htop. I have an Intel i9 9980xe CPU, which has 18 cores and 2 threads per core.
