Bash script scenarios to pass array elements correctly to a function

bash arrays functions Bash

I'm working on a Bash script where I need to pass an array of strings to a function, but I'm working with issues with how the function receives the elements... When I try to pass the array using "${my_array[@]}" syntax, it seems to treat each element individually, but I'm not getting the expected results when I process them in the function. Here is the snippet of my script: ```bash #!/bin/bash my_array=("apple" "banana" "cherry") my_function() { for item in "$@"; do echo "Item: $item" done } my_function "${my_array[@]}" ``` When I run this script, the output is: ``` Item: apple Item: banana Item: cherry ``` This is the expected output, but when I change the way I call the function to use another array, like this: ```bash my_array2=("orange" "grape") my_function my_array2 ``` I get the following behavior: ``` bash: my_array2: command not found ``` I tried to call the function with just `my_function $my_array2`, but it results in similar unexpected behavior where it doesn’t iterate through the elements as I expected. I also attempted to use the `eval` command but that led to more confusion and errors. What am I doing wrong here, and how can I correctly pass the entire array to the function without running into these issues? I'm using Bash version 5.1.8 on Ubuntu 20.04. Any insights would be greatly appreciated! The stack includes Bash and several other technologies. What am I doing wrong?
