If supported, which version of zsh should I use to take advantage of this feature? How to declare and use it in code?

1 Answer 1


Zsh supports hash tables, a quick google search returns many results.

You must first typeset the variable:

% typeset -A hash

then you can store items in the table:

% hash[brown]="mm..  hash browns"
% hash[table]="clever data structure"

then you recover them as usual with arrays:

% print ${hash[brown]}

    Just a remark: This kind of variables are called associative arrays in zsh.

    So they are in PHP, also; it's the rest of the world that calls them hash tables.

    in PHP they are hash tables but, associative arrays don't have to be hash tables: stackoverflow.com/questions/3134296/… Apr 27, 2021 at 16:59
