See if Linux is 32-bit or 64-bit

Method One:

File/sbin/init or File/bin/ls

The results are as follows

[Email protected] ~]# File/sbin/init

/sbin/init:elf 32-bit LSB Shared object, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for gnu/li Nux 2.6.18, stripped

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

/bin/ls:elf 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for Gnu/linux 2. 6.18, stripped

If 32bit is displayed as 32 bits, 64bit is 64 bits.

Method Two:

[Email protected] ~]# uname-a

Linux localhost.lw 2.6.32-358.el6.i686 #1 SMP Thu Feb 21:50:49 UTC i686 i686 i386 gnu/linux

The display x86_64 is represented as 64 bits and the i686 is 32 bits.

Method Three:

[Email protected] ~]# getconf long_bit

32
