Hi guys ,, I have two files , one contain data like this 
data.txt
hello.pl~45~warning~454~null pointer
hello.pl~43~warning~454~memory
hello.pl~4532~warning~454~badpointer
hello.pl~22~warning~454~null pointer
hello.pl~88~warning~454~null pointer

where the first number in each line indcating the line number. in my second file I have only line numbers that been changed , somthing like this 
lineChanged.txt
22-33
90
42-44
100

[download]
where 22-33 indicating that line 22 to 33 have changed. so what I need to do is reading from the lineChanged.txt file each line and see if they appear in data.txt or they are in the range , if it does then I want to print that line from the data.txt and send it to a an output file , so in my example , my output will be 
hello.pl~43~warning~454~memory 
hello.pl~22~warning~454~null pointer

since they appear in both files I am doing somthing like this right now but it is not doing the work 
while (<CHANGES>) {
  chomp;

  # split the line from the spaces
   # $file is file name like hello.pl
  $info = $_;
   is it a range or a single line?
  if ($info =~ /(\d+)-(\d+)/) {
        $changes{$file} .= " ".join(" ",($1 .. $2))." ";
    } else {
        $changes{$file} .= " $info ";
    }
if (defined $changes{$file}) {
    # was it a range?
       if (defined $changes{$file}->[1]) {
      # skip if this $line is not in this range
       next unless ($line gt $changes{$fill}->[0] and $line lt $change
+s{$file}->[1]);
       } else {
      # skip if this $line is not equal to this single line number
       next unless $line eq $changes{$file}->[0];
      }

    # if we are here, then this is a match. so print it.
     print "############ Here ################\n";
    # print "$_\n";
   
    #print "############ Here ################\n";
    }
