Hi guys,

I am looking for such a perl program that matches a pattern in file and print all remaining lines below the pattern.

for example.

If i have a file like..

Column1 Column2

ABC DEF
GHI KJL
ADG MKO
HGI KIO
HFO PIL


This is a my pattern

Groupname GroupLabel Id
ABC Function 123
DER Fucntion1 478

------------------------------

Now i want to print all the lines after 'This is a my pattern' keyword i.e.,

Groupname GroupLabel Id
ABC Function 123
DER Fucntion1 478


Please help me out

Thanks in advance

Hello Guys,

Atlast i have done it here is the code.

#!/usr/bin/perl -w
use strict;
use warnings;

my $InputFileName = 'C://New Folder//Data_File.txt';
my $OutputFileName = 'C://New Folder//Data_All_File.txt';
my $string = 'My pattern Analysis';
my $strLine;
my $a = 0;
my $new_count;
my $new_arr;

die "Usage: $0 <inputfile_name> <outputfile_name> <string>\n" unless ($InputFileName and $OutputFileName and $string);
open(IN,"<$InputFileName") or die "Could not open input: $!\n";
open(OUT,">$OutputFileName") or die "Could not open output: $!\n";

while(<IN>) 
{
$strLine = $_;
#print $strLine;
if ($strLine =~ /$string/)
{
#next;
$new_count = $a;
my @new_arr = <IN>;
print OUT @new_arr;

}
$a++;
}
