in thread Recursive search

Thanks cdark and corion but when I open the filehandle I only see the first line in the file getting stored,confused on what is wrong? 
    my $plf = shift;
    print "\nPLF in recursion:$plf\n";
    open my $fh, '<', $plf or die "could not open '$plf' $!";
       foreach (my $line = <$fh>)
        {
           print "LINE:$line"; #prints ,just the first line
            if($line =~ /\/(.+?\.plf)$/)
            {
                print "LINE CONDITION:$line"; #never comes here
                #print $1;
                $match_plf_name = $1;
                next if $match_plf_name eq $plf;   
                push @recursive_plfs ,$match_plf_name;
                recursion($match_plf_name);
            }
        }
}

    perl mystery:

    You forgot perldoc chomp. Alternatively, you can remove the $ from your regex.

      I did try chomp as below,didnt make a difference? 

      sub recursion
{
    my $plf = shift;
    print "\nPLF in recursion:$plf\n";
    open my $fh, '<', $plf or die "could not open '$plf' $!";
    chomp $fh;
       foreach (my $line = <$fh>)
        {
           chomp $line;
           print "LINE:$line";
            if($line =~ /\/(.+?\.plf)/)
            {
                print "LINE CONDITION:$line";
                #print $1;
                $match_plf_name = $1;
                next if $match_plf_name eq $plf;   
                push @recursive_plfs ,$match_plf_name;
                recursion($match_plf_name);
            }
        }
}
