Not a security question - moved to Hardware.

You can also do a

Code:
# cat /proc/cpuinfo
and that will give you info about your CPU(s).

Cheers,
W.

I think
Code:
uname -m
is more acceptable. It still doesn’t tell you whether you have an x86_64 processor—only that you are running an x86 or x86_64 kernel.

Post to us what this outputs:
cat /proc/cpuinfo

wanghao 10-03-2007 07:51 PM
yes,all right.
it can be judged by the type of cpu.Good idea,i'm noob.

Intel 64 bit architecture
 
For intel 64 bit architecture that is em64t
One need to check for the pni or lm (may be both) flags in /cat /proc/cpuinfo
