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.

cat /proc/cpuinfo

yes,all right.
it can be judged by the type of cpu.Good idea,i'm noob.

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
