hello all
i am using perl script to match two different pattern from same file and wish to print one after the other. but instead the result of only 2nd pattern is correct. the first pattern doesn't move from line1 of input file.
can anyone help me 
#!/usr/bin/perl
use strict;
use warnings;

my ($file1) = @ARGV;

open(FILE, "<","$file1") or die "Can't Open File1\n";

my $pattern='^LOC';
my $pat='TAAAT';

while (my $line1 = <FILE>)
{
        chomp($line1);
        #print "Line1:$line1\n";
       
    if( $line1=~ /$pattern/)
        {
        while (my $line2 = <FILE>)
                    {
                            chomp($line2);
            #print "Line2:$line2\n";

                          if($line2 =~ /$pat/)
                             {            
                                 print "\nMatches: . $line1\n";
                    print "Matches: . $line2\n";
                    
                               }
                        else
                {
                    print "";
                                    }
                }
        
                
        } 
}
close(FILE);
