Judgment method: 1. Use the uname command, syntax "uname -a" or "uname -m", the output "x86_64" is 64-bit; 2. Use the arch command, directly execute "arch" ; 3. Execute the "getconf LONG_BIT" command and the output is "64"; 4. Use the file command with the syntax "file /sbin/init" or "file /bin/ls". If the output information contains x86_64, it means 64-bit.

#The operating environment of this tutorial: linux7.3 system, Dell G3 computer.

How to determine whether the system is 64-bit in Linux

Method 1: Use the uname command

uname can display information about the computer and operating system.

As shown in the following example, x86_64 represents a 64-bit system.

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

[root@gettestlnx01 ~]# uname -m
x86_64

  • -a or --all : Display all information.

  • -m or --machine: Display the computer type.

Method 2: Using the arch command

The arch command is mainly used to display the hardware structure type of the current host. The results output by the arch command are: i386, i486, mips, alpha, etc. Where x86_64 represents a 64-bit system.

[root@DB-Server ~]# arch
i686

[root@gettestlnx01 ~]# arch
x86_64

Method 3: Use the getconf LONG_BIT command

as shown in the following example: 32-bit Linux system displays 32, 64-bit Linux system displays 64 . The simplest and fastest way.

[root@gettestlnx01 ~]# getconf LONG_BIT
64

Method 4: Use the file command

Linux file command is used to identify files type.

[root@gettestlnx01 ~]# file /sbin/init
/sbin/init: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped

[root@gettestlnx01 ~]# file /bin/ls
/bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped

How to determine whether the system is 64-bit in Linux

The output information contains x86_64 to indicate a 64-bit system.
