@RastaJedi: "$@" expands to a list, "$*" expands to a single string. The special behavior of $@ applies when it's within double quotes.

Downvoted because this is not a very complete or helpful answer. Saying "Google it" shows a lack of effort, especially considering that the vast majority of people end up here from Google search. I think the least you could do is add links to official documentation. TBH, the only reason I didn't flag it for deletion was because it is at least a partial answer to the question. I know it's old, but please consider editing it to provide more detail.
