If you wanted to pass arguments to a function that you made, how would you do it?

• A. The same as calling a command with arguments; you reference them with $1, $2 inside the function.
• B. You can't pass arguments to functions.
• C. You pass arguments by exporting environment variables.
• D. You must quote arguments and can't reference them inside function.

Answer: (A)

Passing arguments to a function works just like passing arguments to a command: you call the function with values after its name, and those values become the function’s positional parameters. Inside the function, you access them as $1, $2, and so on. For example, a function written as

myfunc() {

echo "first=$1, second=$2"

}

myfunc "hello" "world"

will print first=hello, second=world. You can also use "$@" to handle all arguments or loop over them, and you can use shift to move through the list. Arguments are not passed via environment variables, and you can reference them inside the function with $1, $2, etc.
