Why are you trying to check from the shell? What problem are you trying to solve by knowing which CPU? (The problem is that it's inherently *very* racy - the process could easily get bounced across 2 or 3 different CPUs in the amount of time it takes a shell command to check - and on large SGI UV boxes under sufficient memory thrashing, it could bounce across 50 or 60 different cores while you check). And checking the *current* process tells you even less than "checking the process you care about" - because unless it's a shell builtin, when you launch the command, it will quite possibly end up on some core other than the one the shell is running on....
