![]() ![]() It currently supports DMI (x86 and IA-64 only), OpenFirmware device tree (PowerPC only), PCI/AGP, CPUID (x86), IDE/ATA/ATAPI, PCMCIA (only tested on x86), SCSI and USB. You can use one of the following methods to determine the number of physical CPU cores. on DMI-capable x86 or IA-64 systems and on some PowerPC machines (PowerMac G4 is known to work). It can report exact memory configuration, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed, etc. lshw is a small tool to extract detailed information on the hardware configuration of the machine. Know more about inxi command – Click Here inxi shows system hardware, CPU, drivers, Xorg, Desktop, Kernel, GCC version(s), Processes, RAM usage, and a wide variety of other useful information. It is also used for forum technical support, as a debugging tool, to quickly ascertain user system configuration and hardware. inxi is a command line system information script built for for console and IRC. To get all the CPU information of the system, run the below command: lscpu The output shows the system CPU features: Architecture: X8664, which shows the CPU is 64bit x86 type. The primary purpose of inxi is for support, and sys admin use. Method 1: Using lscpu Command The lscpu (list CPU) command utility is used to obtain details about the CPU architecture. It is available in most Linux distribution repositories, and also runs somewhat on BSDs. Inxi is a full featured CLI system information tool. ![]() ![]() The cpuinfo shows a detail information about the CPU. Most of it is read-only, but some files allow kernel variables to be changed. The proc filesystem is a pseudo-filesystem which provides an interface to kernel data structures. Proc is the process information pseudo-filesystem. There is also information about the CPU caches and cache sharing, family, model, bogoMIPS, byte order, and stepping. /proc/cpuinfo output is generated by kernel code you can check that code and do the same in your kernel module. When you have some spare time, take a look at the /proc filesystem on your Linux system for other system information you can find, including /proc/loadavg, /proc/vmstat, and much more.The information includes, for example, the number of CPUs, threads, cores, sockets, and Non-Uniform Memory Access (NUMA) nodes. Here are six ways to get that information on Linux. I hope these Linux processor and memory commands have been helpful. Sometimes, you need to get information about the CPU on a machine, whether it's because you just can't remember what kind of CPU your computer has or you need a specific detail, such as the number of cores or whether it's 32- or 64-bit. If the value is greater than 100, truncate it to 100. Call the getloadavg () (or alternatively read the /proc/loadavg ), take the first value, multiply it by 100 (to convert to percents), divide by number of CPU/cores. Summary: Linux processor and memory commands Read /proc/cpuinfo to find the number of CPU/cores available to the systems. When I issue the Linux memory information command, I see the following output:Īs you can see, my current Linux system has 2 GB RAM, with all the additional memory information shown there. Model name : Intel(R) Pentium(R) 4 CPU 3.00GHzįlags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe constant_tsc pni monitor ds_cpl cid xtprįrom that output I can see my current system is a two-processor Intel system, with additional information about the Intel CPU (CPUs, actually). When I issue that Linux processor information command on my current hardware system, I see this output: (See below for sample output.) Linux processor command output To see your Linux memory information and memory stats use this command: (See below for sample processor output.) How to show Linux memory information To see what type of processor/CPU your computer system has, use this Linux command:Īs you can see, all you have to do is use the Linux cat command on this special /proc/cpuinfo file on your Linux system.
