NAME                                                     SHIFT(I)
     shift - adjust Shell arguments

SYNOPSIS
     shift [ digit ]

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 argu-
     ments to a	command	file.  For example, the	command	file

     while "$1"
	     pr	-3 $1
	     shift
     end

     prints each of its	arguments in 3-column format.

     Shift is executed within the Shell.

     The optional argument causes shift	to leave shell	arguments
     numbered  lower than $digit alone on shifts; shift	alone and
     shift 1 are identical in effect.
