sed & awk, 2nd edition
by Dale Dougherty & Arnold Robbins


Here are the changes that were made for the 8/98 reprint:

{24} code sample 1, replaced last four lines

	$1 != LastState {
	      LastState = $1
	      print $1
	}'

with

	$1 != LastState {
	      LastState = $1
	      print $1
	      print "\t" $2
	}'


{29} Figure 3-1, section 3:  the two letter a's in "jar" and "abe"
are now in bold, as they are in section 6.


{39} Table 3-3, row 8, column 2:  changed "Alphanumeric characters"
to "Printable characters (includes whitespace)"


(105) para. 1, line 3:  changed "Writing sed Scripts," to "Writing
sed Scripts)"  (changed comma to close parenthesis.)


{153} code sample 5:  added a blank line between 2 and 3 lines so
that the sample now reads as follows:

	John Robinson, 696-0987
	Phyllis Chapman, 879-0900

	2 records processed.


{171}  para. 2:  added a footnote to the end of the line
"Here's the info script using awk:".  The footnote text is

  Remember that you need an awk that provides POSIX semantics for
  this to work.  It may be named awk, nawk, or even something else!
  Check you local system documentation.

("awk" and "nawk" are in bold.)


{195} code sample 1: changed lines 5 through 7 from

			if ( $i in acro ) {
				# if it matches, add description
				$i + acro[$i] " (" $i ")"
to
			if ( $i in acro ) {
				acronym =$i
				# if it matches, add description
				$i = acro[$i] " (" $i ")"


{236} code sample 4, added dash at the end of the line.  The line
now reads

	awk -v CMDFILE="uucp_commands" script -

("script" is still constant-width italic font.)


{274} code sample, changed alignment so that it now reads

	a[1][1] = "hello"
	a[1][2] = "world"
	for (i in a [1])
		print a[1][i]
