RE: SUMMARY: Sed Question

All, the solution was sent to me by "no spam".  Here is the solution I used.

nawk '{
ARR[NR] = $0
print $0
if ( NR > 3 ) {
	if ( ARR[NR-2] == "I am trying to add a line" && ARR[NR-1] == "after this
text only if" &&
           ARR[NR] == "all lines of text in this message" && ARR[NR] ==
"are found in this order." )
		print "It worked!  I've added the line!"
}' infile


Thanks again for everyone's help!
