Tips and tricks for understanding this document:
- The dollar sign refers to the terminal prompt. The text after it is what you type in. The lines without
$
is the terminal's response. (This holds except for in telnet, in which inputs and responses unfortunately look the same. But fortunately, you're smart.)
$ ping google.com
PING google.com (74.125.239.128): 56 data bytes</code>
- When a word doesn't make sense, either 1) Cmd-F to see if I explain it later on in the doc or 2) let me google that for you.
