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).
