I want to install a package and it has a version for 32-bit ubuntu and 64-bit. How can I tell which one is running on my server?

Answer 1

You know when you're typing out a question it lists similar ones? Well it makes sense to look at them in case the question has been asked before;

Determine Linux Server's Architecture (32 or 64 bit)

Answer 2

um.. if anyone else wants to know, I figured it out:

uname -m

Answer 3

use the command

uname -a

read the string. It will be near the end. Example:

Linux ora100 2.6.5-7.252-smp #1 SMP Tue Feb 14 11:11:04 UTC 2006 x86_64 x86_64 x86_64 GNU/Linux

Answer 4

If you have a 64bit server, it can run either one (32 or 64) but I would stick with 64bit whenever possible. And Ubuntu usually sticks with the one that it was installed with in my case.

Answer 5

If you want to check the version of the package and not the version of the server, do either one of the following commands:

dpkg -s <packagename>
dpkg -p <packagename>

to print out the details of the package. For example, it will look like this:

$ dpkg -s zip
Package: zip

Description: Archiver for .zip files
 This is InfoZIP's zip program. It produces files that are fully
 compatible with the popular PKZIP program; however, the command line
 options are not identical. In other words, the end result is the same,
 but the methods differ. :-)
