@user21546, you don't have the quotes around the ENDSSH keyword, you only removed the escapes from the $s. Which means the variable gets expanded by the script calling ssh, and it doesn't have a value there, so you get empty. I meant you could write ssh -t ... << "ENDSSH" (or << 'ENDSSH'), literally, with the quotes. But it doesn't matter, if you leave the terminator unquoted, then just escape the $s, as in your original code. That part is just a style issue.
