How to get variable values back from commands executing remotely via ssh.
So now I can not figure out how to return a value from within this SSH block. So as in the above discussion I can pass parameters from my local machine to the commands running on a remote machine via ssh:

Code:
filepath=/xxx/yyy/zzz/
filename=xyz

ssh uid@hostname /bin/sh -s $filepath $filename << 'ENDSSH'
filepath=$1
filename=$2
.
.
if [[ -e ${filepath}${filename} ]]; then
....
....
fi

ENDSSH

Now I want to send a return code or messages that are produced on that remote machine and get those values back onto my local server where the code is running to decide what to do based on success or not on the remote server. I've searched and not found a solution that works to do this. (this is a korn shell by the way) How can I get variable values back from within that ENDSSH block?

ssh-keysign

SSH-KEYSIGN(8)						    BSD System Manager's Manual 					    SSH-KEYSIGN(8)

NAME

     ssh-keysign -- ssh helper program for hostbased authentication

SYNOPSIS

     ssh-keysign

DESCRIPTION

     ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during hostbased authentication with
     SSH protocol version 2.

     ssh-keysign is disabled by default and can only be enabled in the the global client configuration file /etc/ssh/ssh_config by setting
     HostbasedAuthentication to ``yes''.

     ssh-keysign is not intended to be invoked by the user, but from ssh(1).  See ssh(1) and sshd(8) for more information about hostbased authen-
     tication.

FILES

     /etc/ssh/ssh_config
	     Controls whether ssh-keysign is enabled.

     /etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key
	     These files contain the private parts of the host keys used to generate the digital signature.  They should be owned by root, read-
	     able only by root, and not accessible to others.  Since they are readable only by root, ssh-keysign must be set-uid root if hostbased
	     authentication is used.

SEE ALSO

     ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)

AUTHORS

     Markus Friedl <markus@openbsd.org>

HISTORY

     ssh-keysign first appeared in OpenBSD 3.2.
