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.
