Hi monks, I have the following script to compare two text files.

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

my $f1 = $ARGV[0];
open FILE1, "$f1" or die "Could not open file \n";
my $f2= 'res1.txt';
open FILE2, "$f2" or die "Could not open file \n";

my $outfile = $ARGV[1];

my @outlines;
my $n=0;
my $n1=0;
my $n2=0;
foreach (<FILE1>) {
my $y = 0;
my $outer_text = $_;

seek(FILE2,0,0);
foreach (<FILE2>) {
my $inner_text = $_;

if($outer_text eq $inner_text) {
$y = 1;
print "$outer_text, Match found \n";
$n++;

last;
}
}

if($y != 1) {
print "$outer_text,No Match Found \n";
push(@outlines, $outer_text);
$n1++;
}
$n2++;
}
print "Total No.of queries:$n2\n";
print "No.of matched entries:$n\n";
print "No.of Mis-matched entries:$n1\n";
my $precision=$n/$n2;
print "The precision is:$precision\n";
open (OUTFILE, ">Nonmatch") or die "Cannot open $outfile for writing \
+n";
print OUTFILE @outlines;
close OUTFILE;

close FILE1;
close FILE2;

The script compares the two text file and gives the no.of matches and no.of mismatches. Also it writes mis-match into seperate file.

My doubt is when comparing the two file, if the 1st file has a sentence in line2(for e.g) and the 2nd file has empty space at line2, what happens is it takes that also has a mis-match. But what i want is, i want to differetiate the no.result(i.e empty space) from mis-match..

How can i do that.. Plz suggest me in this... Thanks..
