In a script I build up a lit of filters that I want to apply to the output of a program.
This list may vary (tee, sort, uniq, ts, etc.) Could be all of them or none of them or any combination.
So I built up a list in a variable (_ql_append)

So _ql_append will have something like this in it:

"ilts -S -E | tee":
then the script executes this line:

( echo "$@"; "$@" ) | $_ql_append > "$_ql_filepath" 2>&1

TL;DR - Solved it.  $HOSTNAME isn't set in interactive shh session

wwalker@polonium:~ ✓ $ head ~/.tmux.conf
#new -s $HOSTNAME
set-hook -g session-created "rename-session $HOSTNAME"
#rename-session $HOSTNAME

# This works:
wwalker@serenity:~ ✓ $ ssh polonium
