Note that the number of processing units might not always be the same as number of cores. The nproc command just prints out the number of processing units available. Lshw command examples to get hardware information on Linux 5. To learn more about the lshw command check this post: However it is not possible to deduce the number of cores on the processor from the above output. The vendor, model and speed of the processor are being shown correctly.

The lshw command can display limited information about the cpu. Hardinfo also performs a few benchmark tests taking a few minutes before the report is displayed. The report can also be written to a text file. The cpu information is towards the beginning of the report. It would produce a large report about many hardware parts, by reading files from the /proc directory. But it can also run from the command line only if there is no gui display available. Hardinfo is a gtk based gui tool that generates reports about various hardware components. It would simply print the cpu hardware details in a user-friendly format. Lscpu is a small and quick command that does not need any options. lscpu - display information about the CPU architecture This indicates that there are 4 actual cores. To get the actual number of cores, check the core id for unique values $ cat /proc/cpuinfo | grep 'core id' For example a processor with 2 cores and hyperthreading would be reported as a processor with 4 cores. To count the number of processing units use grep with wc $ cat /proc/cpuinfo | grep processor | wc -lĤ The number of processors shown by /proc/cpuinfo might not be the actual number of cores on the processor.

The /proc/cpuinfo file contains details about individual cpu cores. In this post we shall take a look at some of the commonly used commands that can be used to get details about the cpu. 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.There are quite a few commands on linux to get those details about the cpu. I hope these Linux processor and memory commands have been helpful. Summary: Linux processor and memory commands 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.

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.
