I was not able to determine by searching whether this question has already been asked and answered. My search always turned up some other 32 versus 64 bit question.
I want to know if it is possible to determine whether an inactive Ubuntu install, that is, on a drive you did not boot from, is the 32-bit or 64-bit version. I cannot use
uname -m because the Ubuntu I want to know about is not the Ubuntu which is running.
For example, if Ubuntu is installed on the hard drive of a desktop PC and the PC is booted from a Live CD/USB version of Ubuntu is it possible to tell what is installed on the hard drive just by looking at the file system of the Ubuntu on the hard drive?
