What's the easiest way to find out that, for example, /Volumes/Foo lives in /dev/disk0s2 ? EDIT: mount is probably a more semantically satisfying answer, but it doesn't get much shorter than df
How are "nslookup," "dig," and "host" different (in terms of looking up hostnames or IP addresses)? Which authorities are queried? I'm trying to figure out when I should use one over the others.
