	On what OS? On linux, you can do:

time foo
	to get the run time for program foo, including elapsed clock time,
time spent in the program itself and time spent in the kernel on
behalf of the program (for I/O, mallocs, etc);

cat /proc/$(pidof foo)/status
	to get memory information for a running program. I don't know any
way to get the memory information once the program exits.
