Now the vast majority of users are using the Windows system, all know that the Windows system has 32-bit and 64-bit, in fact, the Linux system also has 32-bit and 64-bit, you know your Linux system is a few? Here's how you can use the shell to see if Linux is 32-bit or 64-bit.

Manually view the number of system digits

To view the number of Linux system digits, you can perform the following two commands individually

Getconf Word_bit

Used to get the number of digits in Word

Getconf Long_bit

The number of digits used to get long

For 64-bit systems above two commands should be 32 and 64 respectively.

To determine whether the Linux system is 32-bit or 64-bit has a lot of methods, recommended with getconf, however, some people think getconf word_bit=32 is 32bit,getconf word_bit=64 is 64bit, please go to 64bit machine execution, hehe. Getconf word_bit Show results or 32,why?

In a 32-bit system, the int and long types are typically 4 bytes, and the 64-bit system is of type int or 4 bytes, but long has become a 8-byte inux system that can be

Use "getconf word_bit" and "getconf long_bit" to get the digits of WORD and LONG

Shell determines the number of digits in the system


If [$ (getconf word_bit) = ' $ '] && [$ (getconf long_bit) = ' 64 ']; Then





Add some other way


32 bits: Linux localhost.localdomain 2.6.32-431.17.1.el6.i686 #1 SMP Wed May 7 20:52:21 UTC 2014 i686 i686 i386 gnu/linux

64 bits: Linux demolinux 2.6.32-431.11.2.el6.x86_64 #1 SMP Tue Mar 19:59:55 UTC 2014 x86_64 x86_64 x86_64 gnu/linux

The above is the Linux use Shell to view the Linux32 bit and 64-bit method introduced, in addition to using the Shell view, you can also manually execute commands to view the number of system bits.
