Here's a key to the markup:
	[page-number]: serious technical mistake
	{page-number}: minor technical mistake
	<page-number>: important language/formatting problem
	(page-number): language change or minor formatting problem
	?page-number?: reader question or request for clarification



Confirmed errors:

{23} IN PRINT: Calculating File Size section, 2nd line;
"% du Documents/Outline.doc"

SHOULD BE:
"% du -sk Documents/Outline.doc"


(24)  Firt paragraph;
In the first paragraph, the author speaks about and then demonstrates the "df"
command with the optional "-h" after it.  When this is entered, the schell returns an
error:

df: illegal option -- h
usage: df [-ikln] [-t type] [file | file_system ...]

The options "-i", "-k", "-l", and "-n" work without error, however, none of them
return the same output as described in the book.

AUTHOR: I accidentally developed this passage using the df utility that is
  installed along with the Fink fileutils package.  In addition to the
  points that Dan brings up, please note that you must use the -k option
  to display free disk space in 1024 byte blocks.  By default, Mac OS X's
  df uses 512 byte blocks (which would report 1GB of space as "2097152"
  rather than the "1048576" that the -k option would report).

  If you have Fink installed, you can tell which version of df you are
  using by running the 'which df' command at the shell. If you are using
  Fink's df, you will see:

    /sw/bin/df

  If you are using Mac OS X's df, you will see:

    /bin/df



{95} FROM AUTHOR:  first example;
The reader should install fink-ssl, which will support .Mac's secure IMAP server.
This keeps the reader's password from being sent as plaintext. Please change this
listing to:

  % fink install pine-ssl
  sudo /sw/bin/fink  install pine-ssl
  Password:
  Information about 2304 packages read in 2 seconds.

  The following package will be installed or updated:
    pine-ssl

(the text "fink install pine-ssl" should be styled as userinput)



{102} FROM AUTHOR:  bullet list, item "a.";
This setting will send the user's password in plaintext. If the reader installs pine-
ssl instead of pine (see my previous errata submission), this can be secured.

Please renumber bullet item "b." to "c.", and replace "a." with the following two
bullets:


  a. If you are using secure IMAP, set the inbox-path to {incoming mail server/
      ssl/novalidate-cert/user=username}inbox, as in {mail.mac.com/ssl/
      novalidate-cert/user=dtaylor}inbox.

  b. If you are using insecure IMAP (not recommended if your server supports
      secure IMAP), set the inbox-path to {incoming mail server/
      user=username}inbox, as in {mail.mac.com/user=dtaylor}inbox.

(The text should retain the styling that is already in use: the text between and
including the curly braces should be styled as literal, as should the word "inbox"
that follows the last curly. "incoming mail server" and "username" should be styled
constant width + italic.)
