I want to implement a command line features in the linux terminal as similar to ftp command.
I have used Term::Readline module , it works fine , but when I press tab it displays the files in the current directory , but I wanted my own commands to be displayed
Please help me how to do this using this module itself or referring some other module is also fine

For example :

 
use Term::ReadLine;
  my $term = Term::ReadLine->new('Simple Perl calc');
  my $prompt = "Enter your arithmetic expression: ";
  my $OUT = $term->OUT || \*STDOUT;
  $term->MinLine(1);
  while ( defined ($_ = $term->readline($prompt)) ) {
    my $res = eval($_);
    warn $@ if $@;
    print $OUT $res, "\n" unless $@;
    $term->addhistory($_) if /\S/;
        #print Dumper $term->findConsole();
        #print Dumper $term->Attribs();
        print Dumper $term->Features();
        print Dumper $term->tkRunning();
        print Dumper $term->ornaments(1);
  }
