The Bourne Shell
set command sets positional parameters to the getopt's output, i.e. if
getopt returns something like
-a -b -- test then
$@ will be equal to
-a -b -- test
Note: '--' is used in
set command to resolve problems with parameters that begins with '-' character
In
while loop positional parameters are being processed till '--' (
$1 refers to first positional parameter,
shift deletes first positional parameter)
