Sounds like a bash 3 issue. $ bash --version GNU bash, version 5.2.32(1)-release (aarch64-apple-darwin23.4.0) $ declare -A aaa; aaa[a]=a; aaa[b]=bb; for i in ${!aaa[@]}; do echo "$i --> ${aaa[$i]}"; done b --> bb a --> a

  To elaborate on this, macOS default bash is still stuck (assuming due to licensing) in v3.2.x (released in 2007). Bash got associative arrays in v4 (released in 2009).

You should be getting bash from homebrew anyways.

  Just use the included zsh.

    I like my scripts to run on both linux and macos. It's somewhat limiting, but it saves trouble.

      Linuxes have zsh. If you install zsh on linux or bash on macos, hassle is same ish. Installing homebrew is required but I always do it myself. Although bash is more often the available shell on cloud services.

        Also, most bash scripts run as zsh scripts.

  Or using an OS which doesn’t ship ancient software. Linux exists. It’s pretty awesome.

    Only until you find that your requirement or use case doesn’t work in it.

    There's a time and place for evangelism. This isn't it.

    When they make a decent laptop for linux, maybe I'll switch. I wanted so badly to move to System76, but their screens are awful.

    My employer does not let me install Linux on my Mac.

Many programs on macOS are stuck in the ancient past, due to Apple: <https://web.archive.org/web/20240810094701/https://meta.ath0.com/2012/02/05/apples-great-gpl-purge/ https://web.archive.org/web/20240810094701/https://meta.ath0...>
