I'm trying write a script that can automatically set the display variable on an AIX server to run X applications over telnet, that can be ran from a users .cshrc file. 
#!/usr/bin/perl -w
# /usr/local/bin/gethost.pl

# Find out where I'm calling from
open(WHOPROC, "who -m|"); # open who for reading
    $whoami = <WHOPROC>;
close (WHOPROC);

# print "$whoami";

($name,$port,$month,$day,$time,$host) = 
   split(/\s+/, $whoami);
   chop $host;
       $grab = substr($host, 1,);
#print "$grab\n";   

# Now set the display variable
$display = $grab . ':0.0';
# print "$display\n";

system "sh export DISPLAY='$display'";

Is there a way to make perl set the variable for the parent telnet session?
