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

       If no arguments are supplied, the names of all  op-
       set  are printed.  The form is chosen so as to min-
       ferences from the default options for  the  current
       default   emulation  being  native  zsh,  shown  as
<Z> in zshop-

       tions(1)).  Options that are on by default for  the
       shown   with   the   prefix   no  only  if they are
       options are shown without the prefix no and only if
       In  addition  to  options  changed from the default
       user, any options activated  automatically  by  the
       example,  SHIN STDIN  or INTERACTIVE) will be shown
       The format is further modified by the  option   KSH
       however   the   rationale for choosing options with
       no prefix remains the same in this case.

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

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