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.
