Hello,
Depending on how an empty array is declared, it is not stored with the
same state.
# Empty array declared without parenthesis
unset myArr
declare -a myArr
typeset -p myArr
echo "${#myArr[@]}"
This is an unset variable with the array attribute; you have not assigned a
value.
# Empty array declared without parenthesis
unset myArr
declare -a myArr=()
This is an empty array variable; you have assigned a value.
