    Exclamation 32 or 64 bits Kernel?

    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
    /bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=0x37cdd635587f519989044055623abff939002027, stripped

    $ file /sbin/init
    /sbin/init: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=0x7aa29ded613e503fb09fb75d94026f3256f01e7a, stripped

    up 3 commands mean my kernel is 64 bits?

    My question: What is my kernel, 32 bits or 64 bits? Thanks.
