Hi monks, I am having a number of files in a hierarchial order. Something like It is not like one file inside another, only filenames will be there... Say inside Main, three filenames will be there,sub1.sub2,sub3.......... 
                 Main
---------------------------------------------------------    
 sub1         sub2           sub3       sub4
--------------------------------------------------------  
sub11         sub21         sub31       sub41                   
sub12         sub22         sub32       sub42
sub13         sub23         sub33       sub43

That is main link is Main Under main-> sub1,sub2,sub3,sub4 Under sub1->sub11,sub12,sub13,sub14 Under sub2->sub21,sub22,sub23,sub24 Like this i can have any number of links under sub11 also. I wanted to write a program which will print the link names depending on the level we are specifying using recursion. Say if i am specifying the depth as 3,it shold open 
Main
sub1
sub11
sub12
sub13

then again go back to Main 

sub2
sub21
sub22
sub23

then again go back to Main

etc............. How can I do it with recursion???????????? i tried it like 
#! /usr/bin/perl
@listofLinks=qw(Main)
&fileview

sub fileview
{
  @listLinks=@_;
  #print @listLinks;
  foreach $val (@listLinks)
  {
     
       if ($count<2)
       {

          $count++;
          @newlinks=getlinks($val);
          &fileview(@newlinks);
       }
      &printFile($val);
         
       }
  }
  $count--;
  last if($count==0);
}

sub getlinks
{
$file=$_[0];
open (FH,$file);
@arr=<FH>;
return(@arr);
}
sub printFile
{
open(FH,"$_[0]");
@arr=<FH>;
print "@arr\n";
}
