NAME
       shift - shift positional parameters


SYNOPSIS
       shift [n]


DESCRIPTION
       The  positional  parameters  shall  be  shifted.  Positional  parameter  1 shall be assigned the value of
       parameter (1+n), parameter 2 shall be assigned the value of parameter (2+n), and so  on.  The  parameters
       represented  by  the  numbers  "$#"  down to "$#-n+1" shall be unset, and the parameter '#' is updated to
       reflect the new number of positional parameters.

       The value n shall be an unsigned decimal integer less than or equal to the value of the special parameter
