Command to find 32/64 bit in Linux

Hi,

Can somebody tell me which command will help me find whether the OS is 32 bit or 64 bit.

Regards,
Giridhara Babu Tadikonda.

In Solaris 'isainfo -v' will tell you, but since Linux mostly runs on Intel hardware, there is a 99% chance it is 32.

Well, you're right, but a command would still be nice. 64 bit will become more common as time goes on. We have a 64/32 bit article in our faq section which addresses the question for several platforms. I looked for a linux command but didn't find one.

You can run file on an executable to tell if it is 32/64 bit. Not sure which file in Linux as I know little about it.

This is how I determine which Oracle is installed: file `which oracle`
