Hey everybody. I've been working on this program and I seem to have hit a bit of a problem. I'm stumped. Maybe I'm just overlooking something or whatever but I cannot figure it out. I want it to run at the command line and change filenames in a specified directory using some search and replace patterns. I want it to support 3 command line flags: -q, -i, --force to help modify the behavior. I know something's not working right, but I must have missed it, anybody have any advice?

Here's what I have: 

$cmdline = shift @ARGV;
foreach (@ARGV)
{
  $cmdline = $cmdline . "  " . $_;
}

$old = $cmdline;
$cmdline =~ s/\b-i\b//;

if ($cmdline ne $old)
{
  $old = $cmdline;
  $interactive = 1;
}
else
{
  $interactive = 0;
}

$cmdline =~ s/\b--force\b//;
if ($cmdline ne $old)
{
  $old = $cmdline;
  $force = 1;
}
else
{
  $force = 0;
}

$cmdline =~ s/\b-q\b//;
if ($cmdline ne $old)
{
  $old = $cmdline;
  $quiet = 1;
}
else
{
  $quiet = 0;
}

if ( $interactive = 1)
{
  $quiet = 0;
}

print "\"$cmdline\"\n";

$search = $ARGV[0];    #search pattern
$replace = $ARGV[1];   #replacement pattern
$dir = $ARGV[2];       #directory 


opendir DH, $dir || die "error opening directory, $dir:\n$!\n";
@filez = readdir(DH);
chdir $dir || die "error changing to directory, $dir:\n$!\n";

foreach (@filez)
{
  if (-f $_)
  { 
     $old = $_;
     s/($search)/$replace/;
    
     if ($quiet != 1) 
     {
        print "$old    $_";
     }  
    
     if ($old ne $_) 
     {
        if ($force == 1)
        {
           if ($interactive == 1)
           {
              print "     y/n? ";
              chomp($y = <STDIN>);
              
              if ($y =~ /^[yY]/)
              {
                 rename $old, $_;
              }
           }
           else 
           {
              rename $old, $_;
              print "\n";
           }
        }
     }
     else
     {
        print "\n";
     }
  }
}
