32 or 64 bit system?

Hi.

I'm sshing into another linux machine to compile some stuff...but I'll need to know whether it's a 32 or 64-bit system. Can someone help me out with the command that will tell me?

Thanks.

Try

Code:

uname -a

The output on a 32 bit machine should be something similar to

Code:

Linux hostname 2.6.18-1.2257.fc5 #1 Fri Dec 15 16:06:24 EST 2006 i686 i686 i386 GNU/Linux

The output on a 64 bit machine should be similar to

Code:

Linux hostname 2.6.19-1.2895.fc6 #1 SMP Wed Jan 10 18:50:56 EST 2007 x86_64 x86_64 x86_64 GNU/Linux

Note the i686 on 32 bit and x86_64 on 64bit! For a shorter output you can do simply

Code:

uname -p
