"Assistance to connect to servers via ssh once and collect various commands into separate variables"

Post #303038930 by RudiC on Tuesday 17th of September 2019 09:21:20 AM

Not sure I understand your questions / problems.
Of course, you can adapt the "command substitution" $(...) to fit your needs - in fact, you are required to do so as I only gave a proof of concept.
And, the read VAR1 VAR2 ... assigns each individual command line's output to its respective individual variable - did you try that? The way you propose can't be used as those variables used it the one single ssh session would be defined on the remote system and not expandable (not even existent) on your local system.

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. BSD
