Four commands on my pc:
$ dpkg -l |grep linux-image
Linux kernel image for version 3.4.0 on 32 bit x86 SMP
It means my Ubuntu kernel is 32 bits?
$ uname -a
Linux ny 3.4.0-030400-generic #201205210521 SMP Mon May 21 09:22:02 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
$ file /bin/ls

up 3 commands mean my kernel is 64 bits?
My question: What is my kernel, 32 bits or 64 bits? Thanks.
