    64 bit applications

    I am running Lucid x64 in a multi-boot system (with Win XP Pro 32 and 64 bit, and Lucid 32bit as well).

    Now my question is that when I am booted into my Lucid 64 system (which is my default) and am downloading software/packages from Synaptic or Ubuntu Software Center, am I, by default, getting the 64-bit version of those software/packages? For individual software/package/application how would I know if it is 32-bit or 64-bit?

    Kindly let me know.

    Thanks!!

    You are getting the 64-bit version if the program is arch dependent. Various programs can run on 32-bit or 64-bit hardware with the same binary.

    Thanks for your quick response!

    Need two clarifications, however:

    1. What is "arch dependent"? Is "arch" short for "architecture"? How would I be able to tell if a program is or is not "arch dependent"?

    2. In general, is there a way of finding out if the binary/package is for 32-bit or 64-bit?

    I know little bit about computers but am not a geek by any stretch of imagination...so please pardon my ignorance if my questions are stupid.

    Thanks again!

    If you are installing packages from the repositories, most of them will indeed be 64 bit. The way I spot them is whether the package has 'amd64' in the name, or perhaps 'x86_64'

    If you want to tell if the binary file (not deb) is 32-bit or 64-bit, you can use the 'file' command.

    Example
    Code:
    file /bin/ls
