Linux View system number of bits

Several ways to see how many bits Linux is

Method/Step

2. Method One: getconf long_bit

   Enter the getconf long_bit command on the Linux terminal

   If it is a 32-bit machine, the result is 32

   Linux Code

   [Email protected] ~]# getconf long_bit

   32

   If it is a 64-bit machine, the result is 64

   Linux Code

   [Email protected] ~]# getconf long_bit

   64

4. Method Two: Uname-a

   If it is a 64-bit machine, it will output x86_64

   Linux Code

   [Email protected] ~]$ uname-a

   Linux testweb01 2.6.18-308.4.1.el5 #1 SMP Tue Apr 17:08:00 EDT-x86_64 x86_64 x86_64 Gnu/linux

   As you can see, the output of x86_64 in the results of the uname-a execution indicates that the machine is 64-bit, otherwise the machine is 32-bit

   Linux Code

   [Email protected] ~]# uname-a

   Linux localhost.localdomain 2.6.18-164.el5 #1 SMP Tue 15:51:54 EDT i686 i686 i386 gnu/linux

5. Method Three: File/sbin/init or File/bin/ls

   Example: 32-bit machine

   File/sbin/init

   Linux Code

   [Email protected] ~]# 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

   File/bin/ls

   Linux Code

   [Email protected] ~]# 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 Li BS), for Gnu/linux 2.6.9, stripped

   Example: 64-bit machine

   File/sbin/init

   Linux Code

   [Email protected] ~]$ 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

   File/bin/ls

   Linux Code

   [Email protected] ~]$ File/bin/ls

   /bin/ls:elf 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for Gnu/linux 2.6.9, dynamically linked (uses shared Lib s), for Gnu/linux 2.6.9, stripped

   The 64-bit or 32-bit in the command result can be used to determine whether the machine is 64-bit or 32-bit.
