Top Forums UNIX for Beginners Questions & Answers How to have local shell variables in a ksh script seen on remove server in SSH block? Post 303037291 by DJR on Monday 29th of July 2019 11:45:43 AM

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?

NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling SYNOPSIS
hostname | user@hostname [-l login_name] [command] hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name] [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command] DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally. OPTIONS
