ubuntu 32 or 64?

[galil77]

what is the quickest way to find out if an existing installation of ubuntu is 32 or 64 bit?
Thanks.

Just type:


uname -m


If it is not i686 then it should be 64bit.

You could also check what arch a binary is compiled for. i.e.
file /bin/bash
It should say either "32-bit" or "64-bit" in the third field.
file /bin/bash | cut -d' ' -f3
