I'm writing a shell script, and I need to know the archetecture, ie PPC or Intel. Back in the day, there was a program /bin/arch that told you, but my mac doesn't seem to have it... Is there an easy way I can do this? Grep for something in a logfile? call some other program that spits that out as a side effect?

It would be nice to know what OS Version I'm running too, but that may not be necessary.

thanks
