This article mainly introduces "how to check whether linux is 32-bit or 64-bit". In daily operation, I believe many people have doubts about how to check whether linux is 32-bit or 64-bit. Xiaobian consulted all kinds of data and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the question of "how to check whether linux is 32-bit or 64-bit". Next, please follow the editor to study!

Check whether linux is 32-bit or 64-bit: 1, execute the "getconf LONG_BIT" command, the output 32 is 32-bit, the output 64 is 64-bit; 2, execute the "uname-m" command, the output "x86x64" is 64-bit, and the output "i686" or "i386" is 32-bit.

The operating environment of this tutorial: linux5.9.8 system, Dell G3 computer.

Check whether linux is 32-bit or 64-bit

Method 1:getconf LONG_BIT to view

The following example is shown: 32-bit Linux system displays 32, 64-bit Linux system displays 64. The easiest and quickest way.

[root@DB-Server ~] # getconf LONG_BIT32

[root@gettestlnx01 ~] # getconf LONG_BIT64

Method 2:uname command to view

As shown in the following example, x86room64 represents a 64-bit system and i686 i386 represents a 32-bit system. I686 is only a subset of i386. Cpu support starts with Pentium 2. Previous models do not support it.

[root@DB-Server] # uname-aLinux DB-Server 2.6.18-194.el5 # 1 SMP Tue Mar 16 21:52:43 EDT 2010 i686 i686 i386 GNU/Linux [root@DB-Server] # uname-mi686

[root@gettestlnx01 ~] # uname-aLinux gettestlnx01 3.8.13-16.2.1.el6uek.x86_64 # 1 SMP Thu Nov 7 17:01:44 PST 2013 x86 "64 GNU/Linux [root@gettestlnx01 ~] # uname-mx86_64

Method 3: arch command to view

[root@DB-Server ~] # archi686 [root@gettestlnx01 ~] # archx86_64

Method 4:file command to view

[root@DB-Server] # file / sbin/init/sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped [root@DB-Server] # [root@DB-Server] # [root@DB-Server] # file / bin/ls/bin/ls: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9 Dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped
