Top Forums UNIX for Beginners Questions & Answers Assistance to connect to servers via ssh once and collect various commands into separate variables Post 303039593 by MadeInGermany on Thursday 10th of October 2019 02:37:03 AM
Attention:
ssh -qn is ssh -q -n where -n inhibits reading from stdin - good for ssh -q -n remotehost remotecommand. But it must be ssh -q remotehost < file and ssh -q remotehost << heredoc and ssh -q remotehost <<< herestring because here you want it to read from stdin.

Also I suspect that in a normal here-document the backtick expression `uname -r`is already locally evaluated, so the local result will be passed to the remote host.
A workaround is <<-"EOFSSH" where the quotes should suppress the immediate evaluation of backtick-expressions and all kinds of $-expressions in the following here-document.
