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.
