Am I running 32-bit or 64-bit?

I know this question has been asked a number of times, but my system seems to contradict itself…

Following the answer to this question, I have run the following:

$ uname -a

Linux manaha 3.13.7-x86_64-linode38 #1 SMP Tue Mar 25 12:59:48 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux

$ file /sbin/init

/sbin/init: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=0xc0d86a25a7abb14cad4a65a1f7d03605bcbd41f6, stripped

So, while uname seems to suggest 64-bit, /sbin/init suggests 32-bit. What's happening here?

In computing, the Executable and Linkable Format (ELF) is a common standard file format for executables, object code, shared libraries, and core dumps. In your question /sbin/init: ELF 32-bit LSB shared object identifies ELF as the format for a 32-bit shared object from a shared library. Your operating system is a 64-bit OS that has a 32-bit shared object somewhere in it. There is no contradiction in this.
