NAME
       shift - adjust Shell arguments

SYNOPSIS
       shift

DESCRIPTION
       Shift is used in Shell command files to shift the argument list left by
       1, so that old $2 can now be referred to by $1 and so forth.  Shift is
       useful to iterate over several arguments to a command file.  For
       example, the command file

            : loop
            if $1x = x exit
            pr -3 $1
            shift
            goto loop

       prints each of its arguments in 3-column format.

       Shift is executed within the Shell.
