setopt [ {+|-}options | {+|-}o option_name ] [ -m ] [ name ... ]
       Set the options for the shell.  All options specified either with
       flags or by name are set.

       If no arguments are supplied, the names of all options currently set
       are printed.  The form is chosen so as to minimize the differences
       from the default options for the current emulation (the default
       emulation being native zsh, shown as <Z> in zshoptions(1)).  Options
       that are on by default for the emulation are shown with the prefix
       no only if they are off, while other options are shown without the
       prefix no and only if they are on.  In addition to options changed
       from the default state by the user, any options activated
       automatically by the shell (for example, SHIN_STDIN or INTERACTIVE)
       will be shown in the list.  The format is further modified by the
       option KSH_OPTION_PRINT, however the rationale for choosing options
       with or without the no prefix remains the same in this case.

       If the -m flag is given the arguments are taken as patterns (which
       should be quoted to protect them from filename expansion), and all
       options with names matching these patterns are set.

       Note that a bad option name does not cause execution of subsequent
       shell code to be aborted; this behaviour is different from that of
       `set -o'.  This is because set is regarded as a special builtin by
       the POSIX standard, but setopt is not.
