Bug Thanks, and maybe you can clear this up.

This is cool! I'm sure I have something to learn here, because I had thought that outside of double quotes, $@ and $* were identical. Quoting from the Bash Reference Manual:
Quote:
*Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, it expands to a single word with the value of each parameter separated by the first character of the IFS special variable. That is, "$*" is equivalent to "$1c$2c...", where c is the first character of the value of the IFS variable. If IFS is unset, the parameters are separated by spaces. If IFS is null, the parameters are joined without intervening separators.
@Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is, "$@" is equivalent to "$1" "$2" .... If the double-quoted expansion occurs within a word, the expansion of the first parameter is joined with the beginning part of the original word, and the expansion of the last parameter is joined with the last part of the original word. When there are no positional parameters, "$@" and $@ expand to nothing (i.e., they are removed).
So, please, I've always wondered about this--why should I prefer to use one over the other, and in what circumstances--Does it matter outside of double quotes, and what the heck do the descriptions of the behavior within double quotes mean?
