linux-to see if the system is 32-bit or 64-bit

You can use the command "getconf long_bit" To view if the returned result is 32, the description is 32 bits, and the result returned is 64, the description is 64 bits. You can also use the command "uname-a" To view, the output of the results, if there is x86_64 is 64-bit, not 32-bit.

A few ways to see how many bits Linux is: Check whether the Linux machine is a 32-bit or 64-bit method:

Method One: File/sbin/init or File/bin/ls

The results are as follows:

/sbin/init:elf 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for Gnu/linux 2.6. Stripped,

If the display 64-bit is 64 bits;

File/sbin/init/sbin/init:elf 32-bit LSB executable, Intel 80386, version 1 (SYSV), for gnu/linux2.2.5, dynamically linked (uses shared libs), stripped if displayed as a 32bit;

Method Two: Uname-a

Linux pmx002**.**.** 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT-x86_64 x86_64 x86_64 gnu/linuxx86_64 64-bit machine

Uname-a

Linux pmx0**.**.** 2.6.9-5.elsmp #1 SMP Wed Jan 5 19:30:39 EST 2005 i686 i686 i386 gnu/linuxi686

Represents a 32-bit machine

Method Three: It is also the simplest way to see whether Linux is 32-bit or 64-bit:

Getconf Long_bit

Run the following command on both 32-bit and 64-bit machines, with the following results:

[Email protected] ~]$ getconf long_bit
64
[Email protected]/]# getconf long_bit
32
