set [ {+|-}options | {+|-}o [ option_name ] ] ... [ {+|-}A [ name ] ]
[ arg ... ]
Set the options for the shell and/or set the positional
parameters, or declare and set an array. If the -s option is
given, it causes the specified arguments to be sorted before
assigning them to the positional parameters (or to the array name
if -A is used). With +s sort arguments in descending order. For
the meaning of the other flags, see zshoptions(1). Flags may be
specified by name using the -o option. If no option name is
supplied with -o, the current option states are printed: see the
description of setopt below for more information on the format.
With +o they are printed in a form that can be used as input to
the shell.
If the -A flag is specified, name is set to an array containing
the given args; if no name is specified, all arrays are printed
together with their values.
If +A is used and name is an array, the given arguments will
replace the initial elements of that array; if no name is
specified, all arrays are printed without their values.
The behaviour of arguments after -A name or +A name depends on
whether the option KSH_ARRAYS is set. If it is not set, all
arguments following name are treated as values for the array,
regardless of their form. If the option is set, normal option
processing continues at that point; only regular arguments are
treated as values for the array. This means that
set -A array -x -- foo
sets array to `-x -- foo' if KSH_ARRAYS is not set, but sets the
array to foo and turns on the option `-x' if it is set.
If the -A flag is not present, but there are arguments beyond the
options, the positional parameters are set. If the option list
(if any) is terminated by `--', and there are no further
arguments, the positional parameters will be unset.
If no arguments and no `--' are given, then the names and values
of all parameters are printed on the standard output. If the only
argument is `+', the names of all parameters are printed.
For historical reasons, `set -' is treated as `set +xv' and `set -
args' as `set +xv -- args' when in any other emulation mode than
zsh's native mode.
