Set the options for the shell and/or set the positional parame-
ters, 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 sup-
plied 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 speci-
fied, 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.
