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. 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. asynchronously at the /proc/cpuinfo open time, add a single delay > upfront (if necessary) at that point and simply compute the current > frequency while running showcpuinfo() for each individual CPU. If /proc/cpuinfo file does not list these values or if the library fails to recognise the architecture, then the value will be set. This will output the contents on the command line, and you can press ‘Enter’ to scroll. You can also view the contents of this file directly on the command line by running: less /proc/cpuinfo. If filename is passed, then the file with that name is parsed. As you can see in the screenshot above, all the information like the model name, speed, cache size, is present in the file. Without any argument, parses /proc/cpuinfo. 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). Returns a new Linux::Proc::Cpuinfo object. 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 Dump the flags which denote we have detected and/or have applied bug workarounds to the CPU we're executing on, in a similar manner to the feature flags. The date that this will be published is July 4th. To see your Linux memory information and memory stats use this command: The intent of the bugs field in /proc/cpuinfo is described in the commit message which introduced it: x86/cpufeature: Add bug flags to /proc/cpuinfo. Its a short and sweet process, though Ill show you a couple of ways to process the output. linux CPU CPU - Linux CPU linuxCPU SCVMM 2012 Hyper-V CPU Cpu CPUallows Linux psutil.

(See below for sample processor output.) How to show Linux memory information

Here, we can see, - Number of processors, - CPU vendor, family, model name, - The number of cores the CPU has, - Cache, TLB, clflush and address sizes, - Many. Use the following command to read the contents of the file. 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. The /proc/cpuinfo file contains detailed information about the CPUs in the computer. This page shows how to use /proc/cpuinfo file and lscpu. Understand the system-wide proc files such as meminfo and cpuinfo, and per-process.

You can view /proc/cpuinfo with the help of cat command or grep command/egrep command. Know more details about the /proc file system by referring the proc man page. The /proc/cpuinfo file stores CPU and system architecture dependent items, for each supported architecture. Personal preference of course, but especially for locals, lowercase is good - keep uppercase for globals/environment variables.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 Introduction: One can obtain the number of CPUs or cores in Linux from the command line. Variable names don't need to be in all caps Use your shells string manipulations for simple thingsĪssuming you want everything after the :, you can simply do: value='$” for more details. The latter two can do it all in one go too.

That's not portable unfortunately (not in POSIX), so if you don't have that, the usual options are: pipe to head -n 1, use awk instead and exit early, sed and exit early. m1 to stop at the first match, so you won't get weird results when you run your script on a machine with more CPUs.

Also, quote everything - that's save you some debugging when you need to handle spaces in them - like for the 'model name' property. Grep can open files all by itself, cat isn't necessary in most circumstances.
