In conclusion: what's the conclusion here? Is my CPU a 32-bit or a 64-bit? I know I installed the 32-bit (i386) kernel, but that aside I need to know what my processor is.
Does it?)Īnd finally, lscpu returns: Architecture: i686 Lshw returns two different things: 32-bit motherboard and 64-bit processor (I saw this post here and I thought that the answer applied to my case. Grep /proc/cpuinfo returns flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow constant_tsc amdc1e nonstop_tsc extd_apicid pni monitor cx16 popcnt lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a 3dnowprefetch osvw ibs skinit wdt nodeid_msrĪnd this says that if lm appears highlighted then my CPU is 64-bit well, it's not highlited. So I would need to cut off the model name: string and get rid of the extra spaces.
BASH RETURN PROC CPUINFO HOW TO
This page shows how to use /proc/cpuinfo file and lscpu. You can view /proc/cpuinfo with the help of cat command or grep command/egrep command. The /proc/cpuinfo file stores CPU and system architecture dependent items, for each supported architecture.
here is my query return of 'cat /proc/cpuinfo' processor : 3 vendorid : GenuineIntel cpu family : 6 model : 26 model name : Intel(R) Xeon. I think both /proc/cpuinfo and the output from lscpu have what I need (I would prefer lscpu because it would be slightly more efficient), but the model name is 4 spaces too far away from the manufacturer name. Introduction: One can obtain the number of CPUs or cores in Linux from the command line. What follow are the outputs of four different bash commands that allow the user to query exactly that (width of the CPU): > Forums > Linux Forums > Linux - Hardware: proc/cpuinfo question User Name: Remember Me Password: Linux - Hardware This forum is for Hardware issues. I ask this here because I am now very confused.
BASH RETURN PROC CPUINFO 64 BIT
I want to know FOR SURE if my CPU is a 64 bit or a 32 bit. Linux has a command to retrieve detailed CPU information using cat /proc/cpuinfo.Using this command, users can get CPU and CPUs core information like below. If /proc/cpuinfo file does not list these values or if the library fails to recognise the architecture, then the value will be set.
If filename is passed, then the file with that name is parsed. Without any argument, parses /proc/cpuinfo. The Linux kernel has two primary functions: to control access to physical devices on. to send to parent thread on exit taskcpu which CPU the task is scheduled on. Returns a new Linux::Proc::Cpuinfo object. With that said, below are 9 commands for getting info about your Linux CPU. Understand the system-wide proc files such as meminfo and cpuinfo, and per-process. Essentially, the /proc/cpuinfo contains this all info, every other command/utility gets its output from this file. AST GPU 0.96.I use Debian squeeze on a Toshiba Satellite. Thanks to everybody else who contributed source or docs to the Linux kernel. Know more details about the /proc file system by referring the proc man page. Version: Intel(R) Xeon(R) CPU E5-2670 2.60GHzĭescription: ASPEED Technology, Inc. Signature: Type 0, Family 6, Model 45, Stepping 7 Can someone explain to me some probable reasons behind this? $ cat /proc/cpuinfo | grep -i "cpu Mhz" It is a physical host with no virtualization.
I saw an interesting issue where the cpuinfo file from /proc filesystem shows the cpu clock speed as zero.
