How to find OS architecture

* To find the System (hardware) architecture

$uname -a
will display something link this below.

Linux gisnas.corp.com 2.6.18-8.el5 #1 SMP Fri Jan 26 14:15:21 EST 2007 i686 i686 i386 GNU/Linux

From the end you can see "i686 i686 i386 GNU/Linux" which is the hardware architecture representation.


* To find the OS (operating system) architecture.

$getconf WORD_BIT or $getconf LONG_BIT

32

Both these command will display the loaded OS architecture.
