Hi all,

I am trying to check intermediate range values from two file columns.

My two input files are like this:

(file1.txt)

a 11-23

b 33-39

c 40-45

d 48-58

& (file2.txt)

33-39

40-42

43-46

51-52

From it, I want to match the file2 values to that of file1 (2nd column) with intermediate ranges of values, I want the output to be like:

b 33-39

c 40-42, 43-45

d 45-46, 51-52

I have tried:

@ARGV or die "No input file specified";

open my $first,  '<', $ARGV[0] or die "Unable to open input file: $!";
open my $second, '<', $ARGV[1] or die "Unable to open input file: $!";

print scalar(<$first>);

my $secondHeader = <$second>;

while (<$first>) {
    @cols = split /\s+/;
    $p1   = $cols[1]; 
    $p2   = $cols[2]; 

    my $secondLine = <$second>;
    if ( defined $secondLine ) {
        @sec = split( /\s+/, $secondLine );
        print join( "\t", @cols ), "\n" if ( $p1>=$sec[0] && $p2<=$sec
+[1] || $p1<=$sec[0] && $p2>=$sec[1] ); 
    }
}

Which gives me wrong output:

a 11-23

b 33-39

c 40-45

d 46-58

I am stuck about what argument I should give in the last line to get the proper output.. Plz help
