At least for declare -p. It would be nice if it did, though. Newlines, carriage returns, escape characters, etc.It does in some cases: $ a=($'new \n line' $'and \e esc'); declare -p a declare -a a=([0]=$'new \n line' [1]=$'and \E esc')
I'd expect bash to escape any character not in the POSIX [:print:] class.Although this is just a question of QOL improvement, since the produced declare statement just works as-is. It is not user friendly but code friendly and compact if you use the declare -p foo bar baz >savedvars.sh for later include savedvars.sh
