[Memphis.pm] quotes in program arguments

[Hal Phillips]

Hah!  The single quotes worked!  So, as long as I never encounter those in
the message body, I'm ok.

Thanks Steve!

Hmmm,... I'll try the single quote thing.  Thanks for the tip.  It may work
as long as the incomming message has no single quotes,... unfortunately the
possibility is there and I cannot modify the message.  Yes, I agree it is a
shell issue and not a perl one specifically, however the shell is the
interface used to call the perl, it would be nice to have away around this
issue via an argument or switch...  It's interesting that if the message is
strictly STDIN, it works. i.e. >cat file_containing_message|program.pl

while(<STDIN>)
{
   @array = split //;
}

foreach $c (@array)
{
   if ( $c eq "\"" )
   {
      $c = "\\$c";
   }
   $newstring .= $c;
}
print $newstring;

i don't understand why you can't just put single quotes around
the argument, but anyway... you're S-O-L then.  again, it's
the shell, not perl, that's the cause of your problem.
