Use the directory functions: opendir, closedir and readdir.

opendir DIR, $dir or die "cannot open dir $dir: $!";
my @file= readdir DIR;
closedir DIR;

This will neatly put the list of file names in the @file array (with no \n at the end of each file name).

There is a couple of other things you can improve in your code BTW:

• use Perl style loops over arrays:
  foreach my $file (@file) { print "$file\n"; }
  this is much simpler than using C-style for( $i=0;...) loops, you don't have to use $i and $total any more (BTW $#filenames would give you the last index in the @filenames array, you don't have to use $total)
• do not use chop but chomp instead, it's safer as it will not remove the last character of a string if it is not a newline.

Finally I have no idea why $filename$i =~ s/\*//g; is there? Is there a chance you that you might find a '*' in filenames?
