[SOLVED] 32 or 64, how do you tell?

[d_in_Conduct]

When you sit down at an unfamiliar system, or just plain forgot, how do you tell whether it is running a 32 or 64-bit system?

[tgrimley]

You can do uname -a and it'll tell you the kernel.

[y@w]

uname -m

That will tell you the architecture the machine is on.

i686 for 32-bit and x86_64 for 64-bit systems.

uname -a

That will show you all the kernel info for you system.

[scragar]

Odds are unless it's a server it's a 32 bit system.

Few ways to check for sure though if that's not good enough for you:
firstly on linux

uname -m

or the hardware monitor in windows should let you know.

Thanks to all. That was the information I needed.
