"$@" versus ${1+"$@"}

[Hans Ginzel]

	Ahoj.


   Jaky je rozdil v shellu mezi "$@" a ${1+"$@"} ? 

Podle man bash:

	When there are no positional parameters, ``$@'' and
	$@ expand to nothing (i.e., they are removed).

   Mozna v nejakem shellu to tak nefunguje a je potreba explicitne
otestovat, zda je nastaven alespon prvni parametr. Vite o nejakem takovem? 


	S diky,
