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 argu-
     ments 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.
