Bash return proc cpuinfo5/9/2023 ![]() 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. I hope these Linux processor and memory commands have been helpful. linux CPU CPU - Linux CPU linuxCPU SCVMM 2012 Hyper-V CPU Cpu CPUallows Linux psutil. ![]() 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: Understand the system-wide proc files such as meminfo and cpuinfo, and per-process. (See below for sample processor output.) How to show Linux memory information Know more details about the /proc file system by referring the proc man page. 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 a special file on your Linux system. As we have set virt to No Virtualisation at the beginning, no matches will print No Virtualisation.Linux FAQ: How can I find Linux processor and memory information? (Also written as, How can I find Linux CPU information?, How can I find Linux RAM information?) How to show the Linux CPU/processor A match will signified by the RSTART variable not being 0 and so we check this to find the type of virtualisatiion being utilised. When searching for lines beginning with flag, we search for strings svn or vmx using awk's match function. At the end, print the data in the required format using the variables created. Using /proc/cpuinfo and free -mh along with awk, search for the strings required, using : as the field delimited, set variables accordingly, splitting the output of free -mh further into an array called arr based on " " as the delimiter.

The idea if i could change the information on /proc/cpuinfo so the problem solved. The software will ignore if the system running with Celeron 'D' processor. $ free -m -h total used free shared buff/cache available The only reason why do i need to modify /proc/cpuinfo was because im working for security software. I have spent some time searching for methods, but without luck, and maybe this is an interesting generic problem as involves taking the format of tables that a lot of info is held in and extracting as required so has some generic application. I would like to also combine this info with that of /proc/meminfo or free -mh, so: "AMD Athlon(tm) II Neo N36L Dual-Core Processor, 1300 MHz, 2 cores, 4.7 GB Memory (1.8 GB Free), SVM-Virtualization" with the below output, this would look like (with "1300.000" rounded to "1300") "AMD Athlon(tm) II Neo N36L Dual-Core Processor, 1300 MHz, 2 cores, VMX-Virtualization" (or "SVM-Virtualization" or "No Virtualization") I would like to extract something like the following on a single line:, MHz, cores, Į.g. I know that this sort of thing can often be a very simple trick for sed/awk experts (I don't know how to approach this I would like to pluck info from /proc/cpuinfo and /proc/meminfo (or free -m -h) "why not just ' yum install some-great-tool'?" is not ideal as all of this information is freely available to us right in /proc. The problem that I'm trying to solve is to produce portable output that I can display on all of the servers in our environment to show basic info at login using generic information on all CentOS / Red Hat systems.
