2. After pushing the "$match_plf_name" to "@recursive_plfs,when I try to print it,I only see the first element pushed getting printed,why only one element is getting stored in the array? 

foreach my $plf (@plf_files)
{
    #print $plf;
    if (grep (/\Q$plf\E/i,@file))
    {
    push @recursive_plfs,$plf;
    recursion($plf);
    }
}

sub recursion
{
    my $plf = shift;
    #print "\nPLF in recursion:$plf\n";
    open my $fh, '<', $plf or die "could not open '$plf' $!";
    while (my $line = <$fh>)
        {
           chomp $line;
           #print "\nLINE:$line";
            if($line =~ /\/(\w+\.plf)/)
            {
                #print "LINE CONDITION:$line";
                $match_plf_name = $1;
                print "MATCH PLF:$match_plf_name\n";
                next if $match_plf_name eq $plf; 
                next if ( not grep { /\Q$match_plf_name\E/i } @plf_fil
+es);
                print "IN";
                push @recursive_plfs,$match_plf_name;
                recursion($match_plf_name);
            }
        }
}
foreach my $matchplf (@recursive_plfs) {
print $matchplf;
}
