Shell Bash declaring an array

Question

I am having some issues declaring an array in Bash.

I am trying to use declare -A props

But it gives me an error that states:

  declare -A: invalid option           
  declare: usage: declare [-afFirtx] [-p] [name[=value]] ...]

Any help would be greatly appreciated as the array is currently 0.

I am trying to create an array that stores a key and a value.

declare is a bash built-in. Are you using ksh or bash? — Elliott Frisch

Associative arrays are declared using declare -A. Indexed arrays are declared using declare -a.

If you need the former, check your version of bash bash --version since they were introduced in bash 4.0.
