info '(bash)Special Parameters'

`@'
     Expands to the positional parameters, starting from one.  When the
     expansion occurs within double quotes, each parameter expands as a
     separate word.  That is, `"$@"' is equivalent to `"$1" "$2" ...'.
     When there are no positional parameters, `"$@"' and `$@' expand to
                                                              ^^^^^^^^^
     nothing (i.e., they are removed).
     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
