View the number of CPU cores and operating system versions of Windows, Linux, and Aix

Question: Today I saw an article about viewing CPU and operating system information. I will share it with you, O (CPU _ memory) O!

Understanding CPU architecture http://blog.csdn.net/wyzxg/archive/2009/12/17/5027738.aspx

I briefly summarized the CPU architecture two days ago. Today I will summarize the number of digits supported by various OS systems and the number of digits supported by CPU hardware, because these are frequently used in our daily work, as a daily memorandum, You can strengthen your memory or give yourself a general understanding. At each interval, You can summarize it, slowly, you will find the advantage is that

1. view the Linux operating system and hardware CPU count

View the number of digits in a Linux operating system

If getconf long_bit is 32, it indicates 32 bits.

Eg:

[Root @ dB ~] # Getconf long_bit
32

[Root @ dB ~] # Getconf word_bit
32

You can also view it through CAT/proc/cpuinfo.

Or

[Root @ SVR-db-test ~] # File/sbin/init
/Sbin/init: Elf 64-bit LSB executable, amd x86-64, Version 1 (sysv), for GNU/Linux 2.6.9, dynamically linked (uses SHARED libs ), for GNU/Linux 2.6.9, stripped

View CPU hardware architecture

In Linux, the command arch can be used to preliminarily check the machine CPU type identified by the current system,
For example, "i386", "i38"," i586 "," Alpha "," iSCSI "," arm "," m68k ",
"MIPS", "PPC", "IA64", "x86_64", etc. IA64 and x86_64 indicate that this machine is 64-bit;

Eg:

[Root @ dB ~] # Arch
I686

Or

[Root @ SVR-db-test ~] # Uname-m
X86_64

Or

[Root @ SVR-db-test ~] # Echo $ hosttype
X86_64

3. view the number of CPU and OS digits in Aix

Displays whether the machine hardware is 32-bit or 64-bit.
# Bootinfo-y
64

Check whether the AIX operating system is 32-bit or 64-bit

# Bootinfo-K
64
