Line 3
Line 4 SUN> generate
Line 5 tabint>ERROR: (Variable data)


The data i need to extract is Line 2 but only when Line 1 is "SUN> read db @cmpd unit 60"
and Line 5 is "tabint>ERROR:"

The following cant print Line 2, moreover i am specific that my start and end string belong to line i and i+4.

awk '/SUN> read db @cmpd unit 60/,/tabint>ERROR/ {print}' database_energy.out > tf4

Any help will be greatly appreciated.

-Manali
Code:
[n]awk '/SUN> read db @cmpd unit 60/,/tabint>ERROR:/ {
     if (last_line == "SUN> read db @cmpd unit 60")
        print 
     last_line = $0
}' file

chart::clicker::renderer::line

Chart::Clicker::Renderer::Line(3pm)			User Contributed Perl Documentation		       Chart::Clicker::Renderer::Line(3pm)

NAME

       Chart::Clicker::Renderer::Line - Line renderer

VERSION

       version 2.83

SYNOPSIS

	 my $lr = Chart::Clicker::Renderer::Line->new(
	   brush => Graphics::Primitive::Brush->new({
	     #...
	   })
	 );

DESCRIPTION

       Chart::Clicker::Renderer::Line renders a dataset as lines.

ATTRIBUTES

   additive
       If true, the lines are drawn "stacked", each key accumulates based on those drawn below it.

   brush
       Set/Get a brush to be used for the lines.

   shape
       Set a shape object to draw at each of the data points.  Adding a shape results in:

   shape_brush
       Set/Get the brush to be used on the shapes at each point.  If no shape_brush is provided, then the shapes will be filled.  The brush allows
       you to draw a "halo" around each shape.	This sometimes help to separate the points from the lines and make them more distinct.

METHODS

   draw_point
       Called for each point encountered on the line.
