How to determine if my linux m/c is having 32 or 64 bit Kernel.

[Valentino D'Ostilio]

These answers are OK, but they only give you the version of kernel you 
are RUNNING, not actually what hardware is installed.  (Using the 
suggested steps you could be running a 32-bit kernel on a 64-bit 
hardware platform and never know it!!).  You are better off doing a `cat 
/proc/cpuinfo` to look at details of your CPU(s) as opposed to relying 
on a uname.

Just my .02.
