The list of arguments is actually an array. It is referenced by "$@" or "$*". For example, suppose you pass six arguments to your script. The number of elements (arguments) is given by "$#" or using the array notation "${#@}". Suppose you want to reference the arguments from the 3th to the 5th:
Code:
echo "${@:3:3}"
where the syntax here is "${@:start:count}". Googlin' around I found a detailed insight about the usage of positional parameters: http://wiki.bash-hackers.org/scripting/posparams. Anyway, if you explain your requirement a bit more maybe someone can offer a more specific help.

I think the OP wants to pass an existing array as arguments to a command, not get the arguments to his script.

Good catch! Let's wait for the response.

AFAIK, that is both ends of the same stick.
I think that an array that's passed as an argument will be interpreted as an array, but there should be a single argument first.

Code:
calling_function()
{
    variable="a"
    array=( "x", "y", "z" )
    called_function "${variable}" "${array[@]}"
}

called_function()
{
    local_variable="${1}"
    shift
    local_array=("${@}")
}
That solution was from here :
