The @ command can be used for computations. For example, if you have shell variables $X and $Y, you can set a third variable $Z to their sum by

@Z = $X + $Y

that help at all?

$@ is all of the parameters passed to the script. For instance, if you call ./someScript.sh foo bar $@ will be equal to foo bar . I have never seen the context Serunson described (actually, I got an error trying to use it...)
