bash “read -a” looping on null delimited string variable

In bash 4.4, the readarray command gained a -d option analogous to the same option for read.

$ IFS= readarray -d '' myvar < <(printf "%s\0" 'a b' 'c d')$ printf "%s\n" "${myvar[@]}"a bc d

If you must support earlier versions, you need to loop over the output explicitly.

while IFS= read -d '' line; do    myvar+=( "$line" )done < <(printf "%s\0" 'a b' 'c d')
