Quote:

@ 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).

Streigh out of man bash ;)

... and to make things clearer:

Code:

#!/bin/bash



for i in "$@"; do

        echo $i

done

Code:

# . ./test.sh one two three

one

two

three
