I vaguely recall that "export" is the key command here, but I can't remember if there are any other options that work alongside it.

I'm a bit confused about the options with "declare." I feel like they might not be the right choice for making a variable visible.

I think the command to make a variable visible to child processes is related to exporting it, but I'm not entirely sure which one it is.
