comment How can I find my local mail spool?
Unfortunately, /var/spool/mail/ and /var/mail/ each have only two files: nobody and www-data, neither of which are my username. Thanks for your time.

Oops. When I said "efficient," I meant "fast."

@Salton Thanks. I have not yet tried dd, but I just tried rsync. The real time was about 11.5 minutes and the system time was about 1.5 minutes, according to time.

comment Determining the particular processor on which a process is running
@Mat Thanks for your time. This is a separate question, but ultimately I would like to see if I can assign two calls to foo to two different processors. When I call foo once, it runs with %CPU very close to 100% (according to top). But when I call foo a second time, both foo processes run such that the %CPU for both processes sum to less than 100% (usually about 45% for each foo process). To me, this suggests that the two calls to foo are running on the same processor (even though there are eight processors available); I would like to verify that this is the case.
