Since macOS 10.15 (Catalina) the default shell has changed from bash to zsh. One of the things I'm running into is I cannot get my own global functions working. I used to export these from .bash_profile but zsh doesn't seem to know the concept of exporting functions.

Say I have this:

function greet { echo "Hello $1, how are you today" }

If I then run hello RocketNuts on the shell, it says Hello RocketNuts, how are you today. So far so good.

Now I want to make this function global so that it's also available in scripts.

I have tried:

• putting it in .zshrc
• putting it in .zshenv

I also tried creating a subdir ~/myfunctions and a file called ~/myfunctions/greet which contains:

function greet { echo "Hello $1, how are you today" } greet "$@" 

and then in either ~/.zshrc or ~/.zshenv I add:

fpath=( ~/myfunctions "${fpath[@]}" ) autoload -Uz greet 

However, none of these methods make the greet function available in scripts.

From the shell, they all work fine. With either method, I can invoke the greet function manually on the shell.

But if I have a file test.sh which does greet Somebody and run that, it always says "greet: command not found".

How do I get this working in zsh?
