How do I determine if my linux systems is capable of 64bit processing?

To check if your linux system is capable of 64bit processing run the following:

# uname -a
Linux unixbod 2.6.9-34.ELsmp #1 SMP Fri Feb 24 16:54:53 EST 2006 i686 i686 i386

The system above is only 32bit. A 64bit system has x86_64 or ia64 at the end of the uname output like this:

# uname -a
Linux unixbod 2.6.11-1.27_FC3 #1 Tue May 17 20:24:57 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux

# uname -a
Linux unixbod 2.6.11-1.27_FC3 #1 Tue May 17 20:24:57 EDT 2005 ia64 ia64 GNU/Linux
