sorry I dont have the use of nawk or grep with the -q switch

egrep -v wouldn't get what Im looking for as it wouldnt highlight any errors

sorry I only have limited knowledge of awk and sed so Im not sure how I would use them in this case

What I am looking for is by using grep or egrep or any other command to search though a file for expression1|expression2|expression3 etc... and if it can't find one of the expressions output an error along the lines of "can't find expression1". If it does find the expression in the file then do nothing and output nothing.

Thankyou for all your help so far people Smilie

Spreadsheet::WriteExcel::Chart::Area(3pm)		User Contributed Perl Documentation		 Spreadsheet::WriteExcel::Chart::Area(3pm)

NAME
Area - A writer class for Excel Area charts. SYNOPSIS
To create a simple Excel file with a Area chart using Spreadsheet::WriteExcel: #!/usr/bin/perl -w use strict; use Spreadsheet::WriteExcel; my $workbook = Spreadsheet::WriteExcel->new( 'chart.xls' ); my $worksheet = $workbook->add_worksheet(); my $chart = $workbook->add_chart( type => 'area' ); # Configure the chart. $chart->add_series( categories => '=Sheet1!$A$2:$A$7', values => '=Sheet1!$B$2:$B$7', ); # Add the worksheet data the chart refers to. my $data = [ [ 'Category', 2, 3, 4, 5, 6, 7 ], [ 'Value', 1, 4, 5, 2, 1, 5 ], ]; $worksheet->write( 'A1', $data ); __END__ DESCRIPTION
This module implements Area charts for Spreadsheet::WriteExcel. The chart object is created via the Workbook "add_chart()" method: my $chart = $workbook->add_chart( type => 'area' ); Once the object is created it can be configured via the following methods that are common to all chart classes: $chart->add_series(); $chart->set_x_axis(); $chart->set_y_axis(); $chart->set_title(); These methods are explained in detail in Spreadsheet::WriteExcel::Chart. Class specific methods or settings, if any, are explained below. Area Chart Methods There aren't currently any area chart specific methods. See the TODO section of Spreadsheet::WriteExcel::Chart. EXAMPLE
Here is a complete example that demonstrates most of the available features when creating a chart. #!/usr/bin/perl -w use strict; use Spreadsheet::WriteExcel; my $workbook = Spreadsheet::WriteExcel->new( 'chart_area.xls' ); my $worksheet = $workbook->add_worksheet(); my $bold = $workbook->add_format( bold => 1 ); # Add the worksheet data that the charts will refer to. my $headings = [ 'Number', 'Sample 1', 'Sample 2' ]; my $data = [ [ 2, 3, 4, 5, 6, 7 ], [ 1, 4, 5, 2, 1, 5 ], [ 3, 6, 7, 5, 4, 3 ], ]; $worksheet->write( 'A1', $headings, $bold ); $worksheet->write( 'A2', $data ); # Create a new chart object. In this case an embedded chart. my $chart = $workbook->add_chart( type => 'area', embedded => 1 ); # Configure the first series. (Sample 1) $chart->add_series( name => 'Sample 1', categories => '=Sheet1!$A$2:$A$7', values => '=Sheet1!$B$2:$B$7', ); # Configure the second series. (Sample 2) $chart->add_series( name => 'Sample 2', categories => '=Sheet1!$A$2:$A$7', values => '=Sheet1!$C$2:$C$7', ); # Add a chart title and some axis labels. $chart->set_title ( name => 'Results of sample analysis' ); $chart->set_x_axis( name => 'Test number' ); $chart->set_y_axis( name => 'Sample length (cm)' ); # Insert the chart into the worksheet (with an offset). $worksheet->insert_chart( 'D2', $chart, 25, 10 ); __END__ AUTHOR
