Defined bash commands not found when passed in "do shell script" in osascript

Question

I am new to shell script and recently wrote a script to open a new terminal window and run defined functions via osascript with "do shell script", but the result showed the command not found. My script is as below:

#!/bin/bash

hello() {
    echo "Hello World"
}

openNewWindowAndRun() {
    osascript -e "
        tell application \"Terminal\"
            activate        
            do script \"$1\"
        end tell
    "
}

openNewWindowAndRun hello

I have also tried to directly call the hello function in the openNewWindowAndRun but didn't get any luck:

#!/bin/bash

hello() {
    echo "Hello World"
}

openNewWindowAndRun() {
    osascript -e "
        tell application \"Terminal\"
            activate        
            do script \"hello\"
        end tell
    "
}

openNewWindowAndRun

When I ran the script, it opened the new window successfully but showed the error message:

Does anyone know which part I missed here? Is it possible to pass a defined function as a parameter to osascript? If anyone can give me a hand, that would be great!

Answer 1

hello is a function defined within a shell script, it can only be called by bash code from within the script itself. It is not accessible directly from the command line (your screen shot) nor from within Applescript (your osascript call).

To resolve this, you need to turn your hello function into a shell script itself.
