how to determine if the computer is 32 or 64 bit

Is there a quick way to determine if the computer is 64 or 32 bit?

Via Linux or Windows?

Anyway, rather than reinvent the wheel, have a read of this...

Thanks ferrari, I bookmarked that one.

On linux "lscpu" is perhaps easier to recall than cat proc/whatever/cpu/whatnot.

But maybe you need to have it installed, not being a bare-bones default thing, unlike grepping whatever from somewhere.

(Assuming x86 architecture)

Code:

cat /proc/cpuinfo | grep flags | grep " lm " && echo 64-bit || echo 32-bit

(done this way for readability, not efficiency

)

Code:

getconf LONG_BIT

That command does not give a clue about the processor type. It only tells what size "longs" are in the current environment.

My bad. I stand corrected. I was thinking distro bit type. That command is to determine if your distro is 32 or 64 bit.

The code for cpu info is below. The last line in the output will tell if the cpu is 32 or 64 bit

Code:

dmidecode --type processor

Must be root to run.

PS: Other keywords for dmidecode --type are bios, system, baseboard, chassis, processor, memory, cache, connector, and slot

avoid knowing which is better. people are moving to either "fresh compiled (all 32 all 64) or "off shelf (all 64)"

what i mean is a mixed system needing to have both for disto to "a crowd having either kinda pc) using one distributed tar - is getting more rare
