In my previous question Expect, STDout, and formating I was having difficulty getting output from expect. thanks to the code snipits provided by my fellow monks I am now able to get output, but alas there is a problem making if make sense. normally i wouldnt post a question that could be titled "why wont if make sense" but alas I am totally stuck.

my problems stem from the inconsistencys of expects loging functionality. ie occassionally /bin/sh will be logged as /\nbin/sh. And to top it off dispite having duplicated every case i can thing would effect my output and compensate for the problems no luck was achieved.
hopefully my code will help explain my question more clearly 

 $exp->log_file(\&formatoutput);
 $exp->send("$CAT /etc/passwd\n");
......
sub formatoutput {
  my $input = shift;
     
  chomp($input);
  $input =~ tr/\r//;
 
  if( ($input ne "$CAT /etc/passwd ") ||
      ($input ne '/bin/sh') ||
      ($input ne "/bin/sh") ||
      ($input ne '\$ ') ||
      ($input ne "\$ ") ||
      ($input ne '/') ||
      ($input ne "/") ||
      ($input ne 'bin/sh') ||
      ($input ne "bin/sh")
    )
   {
     print"${input}\n\n";
   }
}

neither of the $'s or the / or bin/sh should be showing up and last run i had the $ and /bin/sh which should also have not shown up, right?
