Hi,
I am using Net::Telnet to read in input from different commands. What is happening, for example, is that I want to be able to telnet into an account, 'cat' a file, and use that file in my perl script. To be more specific, I want to read in data from the ~/.vacation.msg file and then (eventually) display it to the screen. So far, I have gotten this to work for the most part. However, when the .vacation.msg file contains the text $SUBJECT, the perl script fails to store whatever line in which that variable occurs. The below working excerpt, taken from my full program, I believe demonstrates the problem. Forgive me for not including 'use strict' and for other likely sloppy syntax; this program is only for testing purposes: 
 #!/usr/bin/perl

my $username="user1";
my $password="password";
my $host="localhost";
my $CAT = "/usr/bin/cat";
my $LAST = "/usr/bin/last";

&start_login;

print "@vacation_str\n";

sub start_login
  {
    my $telnet = new Net::Telnet; 

    telnet_login($username,$password,$host,\$telnet);

    @vacation_str=$telnet->cmd("$CAT /home/$username/.vacation.msg");
                                  
    telnet_close(\$telnet);       
  }
   
sub telnet_login
{
    use Net::Telnet;
    my ($username, $password, $host, $telnet) = @_;
    my $error_msg = "Incorrect username or password, please try again"
+;
    my $error_type = "ERROR";
    $$telnet = new Net::Telnet ('Timeout'=>'7',
                                'Errmode'=> sub { &report_error($error
+_type,$error_msg); },
                                'Prompt'=> '/.*([\$#\%>~]|\\\[\\e\[0m\
+\\] \[0m)\s?/' );
    $$telnet->open(Host=>$host);
    $$telnet->login($username,$password);
}
 
sub telnet_close
  {
    my $telnet=shift;
    $$telnet->close; 
  }

I believe that perl thinks that $SUBJECT is a variable and is trying to store it into @vacation_str, but failing to do so. I am looking for a way to escape the $ before it is stored into @vacation_str so it won't see $SUBJECT as a variable. I also had my eye on the Net::Telnet functions 'get' and 'getlines' to try take the input a different way. However, I don't know if this is a dead end. I am greatful for any advice that anyone has on this issue. Thanks for reading this. Joe
