how to determine if system is 32 bit or 64 bit?

What the subject says...

What can I look at in my system to determine if it is 32 bit or 64 bit system?

Systems were not installed by me, and even if they were I probably still wouldn't know!

Thanks for your time.

Type in the command"
uname -i
and it will tell you the hardware architecture that the kernel was compiled for.

I get 'unknown' for that.
uname -a
will tell you everything, mine at least tells me that I'm running an i686

dangit I knew about uname...my memory sucks.

in Suse I get nothing for uname -i, but for uname -a I get
"Linux pma50 2.4.19-SMP #1 SMP Mon Jan 27 18:35:48 UTC 2003 ia64 unknown"

So I suppose ia64 would be 64-bit.

In redhat for uname -i I get i386, and for uname -a I get:
"Linux ibmlin82 2.4.20-6smp #1 SMP Thu Feb 27 09:59:40 EST 2003 i686 i686 i386 GNU/Linux"

So I'm still not sure about my redhat install. But what I really wanted to know anyway is if my systems had large file support. ext3 on redhat and reiserfs 3.6 on suse answered that question.

Thanks guys.
