Linux kernel - 32/64 bit

How can you tell in Linux if the server is running 32 or 64 bit ??

Re: Linux kernel - 32/64 bit

One way to tell is by doing a 'uname -a'. If you are running a 64-bit kernel you'll probably see 'x86_64' instead of 'i686' or 'i386', assuming you are running on an Intel processor.
