If you use $(eval echo ...) you are almost always doing it wrong.
eval "r=(\"\${${a_all[1]}[@]}\")"
Andreas.
Thanks. I changed things of the form
r=($(eval "echo "\${${a_all[1]}[@]}\""))
to
eval "r=(\"\${${a_all[1]}[@]}\")"
One place where I can't see how to eliminate the construct is where I pass in
the name of an array and parse it using set
set -- $(eval echo \"\${$name[@]}\")
would I be better off with something like
eval "set -- \"\${$name[@]}\""
?
TIA
