ZSHOPTIONS(1)                                                    ZSHOPTIONS(1)



NAME
       zshoptions - zsh options

SPECIFYING OPTIONS
       Options  are  primarily  referred to by name.  These names are case insensitive and
       underscores are ignored.  For example, 'allexport' is equivalent to 'A__lleXP_ort'.

       The  sense  of an option name may be inverted by preceding it with 'no', so 'setopt
       No_Beep' is equivalent to 'unsetopt beep'.  This inversion can only be  done  once,
       so  'nonobeep' is not a synonym for 'beep'.  Similarly, 'tify' is not a synonym for
       'nonotify' (the inversion of 'notify').

       Some options also have one or more single letter names.  There are two sets of sin-
       gle  letter  options: one used by default, and another used to emulate sh/ksh (used
       when the SH_OPTION_LETTERS option is set).  The single letter options can  be  used
       on the shell command line, or with the set, setopt and unsetopt builtins, as normal
       Unix options preceded by '-'.

       The sense of the single letter options may be inverted by using '+' instead of '-'.
       Some  of the single letter option names refer to an option being off, in which case
       the inversion of that name refers to the option being on.  For example, '+n' is the
       short name of 'exec', and '-n' is the short name of its inversion, 'noexec'.

       In  strings  of  single  letter  options supplied to the shell at startup, trailing
       whitespace will be ignored; for example the string '-f    ' will be treated just as
       '-f', but the string '-f i' is an error.  This is because many systems which imple-
       ment the '#!' mechanism for calling scripts do not strip trailing whitespace.


DESCRIPTION OF OPTIONS
       In the following list, options set by default in all  emulations  are  marked  <D>;
       those  set  by default only in csh, ksh, sh, or zsh emulations are marked <C>, <K>,
       <S>, <Z> as appropriate.  When listing options (by 'setopt', 'unsetopt',  'set  -o'
       or  'set  +o'),  those  turned on by default appear in the list prefixed with 'no'.
       Hence (unless KSH_OPTION_PRINT is set), 'setopt' shows all options  whose  settings
       are changed from the default.


   Changing Directories
       AUTO_CD (-J)
              If  a  command is issued that can't be executed as a normal command, and the
              command is the name of a directory, perform the cd command  to  that  direc-
              tory.

       AUTO_PUSHD (-N)
              Make cd push the old directory onto the directory stack.

       CDABLE_VARS (-T)
              If  the  argument  to a cd command (or an implied cd with the AUTO_CD option
              set) is not a directory, and does not begin with a slash, try to expand  the
              expression as if it were preceded by a '~' (see the section 'Filename Expan-
              sion').

       CHASE_DOTS
              When changing to a directory containing a path segment '..' which would oth-
              erwise  be  treated  as canceling the previous segment in the path (in other
              words, 'foo/..' would be removed from the path, or if '..' is the first part
              of  the  path,  the  last  part  of  the  current working directory would be
              removed), instead resolve the path to the physical directory.   This  option
              is overridden by CHASE_LINKS.

              For  example, suppose /foo/bar is a link to the directory /alt/rod.  Without
              this option set, 'cd /foo/bar/..' changes to /foo; with it set,  it  changes
              to  /alt.  The same applies if the current directory is /foo/bar and 'cd ..'
              is used.  Note that all other symbolic  links  in  the  path  will  also  be
              resolved.

       CHASE_LINKS (-w)
              Resolve  symbolic  links to their true values when changing directory.  This
              also has the effect of CHASE_DOTS, i.e. a '..' path segment will be  treated
              as referring to the physical parent, even if the preceding path segment is a
              symbolic link.

       POSIX_CD
              Modifies the behaviour of cd, chdir and pushd commands  to  make  them  more
              compatible  with  the POSIX standard. The behaviour with the option unset is
              described in the documentation for the cd builtin in zshbuiltins(1).  If the
              option  is  set,  the  shell does not test for directories beneath the local
              directory ('.') until after all directories in cdpath have been tested.

              Also, if the option is set, the conditions under which the shell prints  the
              new directory after changing to it are modified.  It is no longer restricted
              to interactive shells (although printing of the directory stack  with  pushd
              is  still  limited  to  interactive  shells);  and any use of a component of
              CDPATH, including a '.' but excluding an empty component that  is  otherwise
              treated as '.', causes the directory to be printed.

       PUSHD_IGNORE_DUPS
              Don't push multiple copies of the same directory onto the directory stack.

       PUSHD_MINUS
              Exchanges  the  meanings of '+' and '-' when used with a number to specify a
              directory in the stack.

       PUSHD_SILENT (-E)
              Do not print the directory stack after pushd or popd.

       PUSHD_TO_HOME (-D)
              Have pushd with no arguments act like 'pushd $HOME'.


   Completion
       ALWAYS_LAST_PROMPT <D>
              If unset, key functions that list completions try  to  return  to  the  last
              prompt  if given a numeric argument. If set these functions try to return to
              the last prompt if given no numeric argument.

       ALWAYS_TO_END
              If a completion is performed with the cursor within a word, and a full  com-
              pletion  is  inserted, the cursor is moved to the end of the word.  That is,
              the cursor is moved to the end of the word  if  either  a  single  match  is
              inserted or menu completion is performed.

       AUTO_LIST (-9) <D>
              Automatically list choices on an ambiguous completion.

       AUTO_MENU <D>
              Automatically  use  menu completion after the second consecutive request for
              completion, for example by pressing the tab key repeatedly. This  option  is
              overridden by MENU_COMPLETE.

       AUTO_NAME_DIRS
              Any  parameter  that  is set to the absolute name of a directory immediately
              becomes a name for that directory, that will be used by the '%~' and related
              prompt  sequences,  and  will be available when completion is performed on a
              word starting with '~'.  (Otherwise, the parameter must be used in the  form
              '~param' first.)

       AUTO_PARAM_KEYS <D>
              If  a  parameter  name  was  completed and a following character (normally a
              space) automatically inserted, and the next character typed is one of  those
              that  have  to come directly after the name (like '}', ':', etc.), the auto-
              matically added character is deleted, so  that  the  character  typed  comes
              immediately  after  the  parameter name.  Completion in a brace expansion is
              affected similarly: the added character is a ',', which will be  removed  if
              '}' is typed next.

       AUTO_PARAM_SLASH <D>
              If  a  parameter is completed whose content is the name of a directory, then
              add a trailing slash instead of a space.

       AUTO_REMOVE_SLASH <D>
              When the last character resulting from a completion is a slash and the  next
              character  typed  is  a  word delimiter, a slash, or a character that ends a
              command (such as a semicolon or an ampersand), remove the slash.

       BASH_AUTO_LIST
              On an ambiguous completion, automatically list choices when  the  completion
              function  is  called  twice  in  succession.   This  takes  precedence  over
              AUTO_LIST.  The setting of LIST_AMBIGUOUS is  respected.   If  AUTO_MENU  is
              set,  the  menu  behaviour  will then start with the third press.  Note that
              this will not work with MENU_COMPLETE, since repeated completion calls imme-
              diately cycle through the list in that case.

       COMPLETE_ALIASES
              Prevents  aliases  on  the  command  line  from being internally substituted
              before completion is attempted.  The effect is to make the alias a  distinct
              command for completion purposes.

       COMPLETE_IN_WORD
              If unset, the cursor is set to the end of the word if completion is started.
              Otherwise it stays there and completion is done from both ends.

       GLOB_COMPLETE
              When the current word has a glob  pattern,  do  not  insert  all  the  words
              resulting  from  the  expansion  but  generate matches as for completion and
              cycle through them like MENU_COMPLETE. The matches are generated as if a '*'
              was  added  to  the  end  of  the  word, or inserted at the cursor when COM-
              PLETE_IN_WORD is set.  This actually uses pattern matching, not globbing, so
              it  works  not  only for files but for any completion, such as options, user
              names, etc.

              Note that when the pattern matcher is used, matching control  (for  example,
              case-insensitive or anchored matching) cannot be used.  This limitation only
              applies when the current word contains a  pattern;  simply  turning  on  the
              GLOB_COMPLETE option does not have this effect.

       HASH_LIST_ALL <D>
              Whenever  a  command  completion  is attempted, make sure the entire command
              path is hashed first.  This makes the first completion slower.

       LIST_AMBIGUOUS <D>
              This option works when AUTO_LIST or BASH_AUTO_LIST is also set.  If there is
              an  unambiguous prefix to insert on the command line, that is done without a
              completion list being displayed; in other words, auto-listing behaviour only
              takes  place when nothing would be inserted.  In the case of BASH_AUTO_LIST,
              this means that the list will be delayed to the third call of the  function.

       LIST_BEEP <D>
              Beep  on  an ambiguous completion.  More accurately, this forces the comple-
              tion widgets to return status 1 on an ambiguous completion, which causes the
              shell  to  beep if the option BEEP is also set; this may be modified if com-
              pletion is called from a user-defined widget.

       LIST_PACKED
              Try to make the completion list smaller (occupying less lines)  by  printing
              the matches in columns with different widths.

       LIST_ROWS_FIRST
              Lay  out  the  matches in completion lists sorted horizontally, that is, the
              second match is to the right of the first one, not under it as usual.

       LIST_TYPES (-X) <D>
              When listing files that are possible completions, show the type of each file
              with a trailing identifying mark.

       MENU_COMPLETE (-Y)
              On  an  ambiguous  completion,  instead of listing possibilities or beeping,
              insert the first match  immediately.   Then  when  completion  is  requested
              again,  remove the first match and insert the second match, etc.  When there
              are no more matches, go back to the first one again.   reverse-menu-complete
              may  be  used  to  loop through the list in the other direction. This option
              overrides AUTO_MENU.

       REC_EXACT (-S)
              In completion, recognize exact matches even if they are ambiguous.


   Expansion and Globbing
       BAD_PATTERN (+2) <C> <Z>
              If a pattern for filename generation is badly formed, print  an  error  mes-
              sage.  (If this option is unset, the pattern will be left unchanged.)

       BARE_GLOB_QUAL <Z>
              In  a glob pattern, treat a trailing set of parentheses as a qualifier list,
              if it contains no '|', '(' or (if special) '~' characters.  See the  section
              'Filename Generation'.

       BRACE_CCL
              Expand  expressions in braces which would not otherwise undergo brace expan-
              sion to a lexically ordered list of all the  characters.   See  the  section
              'Brace Expansion'.

       CASE_GLOB <D>
              Make globbing (filename generation) sensitive to case.  Note that other uses
              of patterns are always sensitive to case.  If the option is unset, the pres-
              ence  of  any  character  which is special to filename generation will cause
              case-insensitive matching.  For example, cvs(/) can match the directory  CVS
              owing to the presence of the globbing flag (unless the option BARE_GLOB_QUAL
              is unset).

       CASE_MATCH <D>
              Make regular expressions using the zsh/regex module (including matches  with
              =~) sensitive to case.

       CSH_NULL_GLOB <C>
              If a pattern for filename generation has no matches, delete the pattern from
              the argument list; do not report an error unless all the patterns in a  com-
              mand have no matches.  Overrides NOMATCH.

       EQUALS <Z>
              Perform = filename expansion.  (See the section 'Filename Expansion'.)

       EXTENDED_GLOB
              Treat  the '#', '~' and '^' characters as part of patterns for filename gen-
              eration, etc.  (An initial unquoted  '~'  always  produces  named  directory
              expansion.)

       GLOB (+F, ksh: +f) <D>
              Perform  filename generation (globbing).  (See the section 'Filename Genera-
              tion'.)

       GLOB_ASSIGN <C>
              If this option is set, filename generation (globbing) is  performed  on  the
              right  hand  side  of scalar parameter assignments of the form 'name=pattern
              (e.g. 'foo=*').  If the result has more than one  word  the  parameter  will
              become  an  array with those words as arguments. This option is provided for
              backwards compatibility only: globbing is always performed on the right hand
              side  of  array  assignments of the form 'name=(value)' (e.g. 'foo=(*)') and
              this form is recommended for clarity; with this option set, it is not possi-
              ble to predict whether the result will be an array or a scalar.

       GLOB_DOTS (-4)
              Do not require a leading '.' in a filename to be matched explicitly.

       GLOB_SUBST <C> <K> <S>
              Treat  any  characters  resulting from parameter expansion as being eligible
              for file expansion and filename generation,  and  any  characters  resulting
              from command substitution as being eligible for filename generation.  Braces
              (and commas in between) do not become eligible for expansion.

       HIST_SUBST_PATTERN
              Substitutions using the :s and :& history modifiers are performed with  pat-
              tern matching instead of string matching.  This occurs wherever history mod-
              ifiers are valid, including glob qualifiers and parameters.  See the section
              Modifiers in zshexpn(1).

       IGNORE_BRACES (-I) <S>
              Do not perform brace expansion.

       KSH_GLOB <K>
              In pattern matching, the interpretation of parentheses is affected by a pre-
              ceding '@', '*', '+', '?' or '!'.  See the section 'Filename Generation'.

       MAGIC_EQUAL_SUBST
              All unquoted arguments of the form 'anything=expression' appearing after the
              command  name have filename expansion (that is, where expression has a lead-
              ing '~' or '=') performed on expression as if it were  a  parameter  assign-
              ment.   The argument is not otherwise treated specially; it is passed to the
              command as a single argument, and not used as an  actual  parameter  assign-
              ment.   For example, in echo foo=~/bar:~/rod, both occurrences of ~ would be
              replaced.  Note that this happens anyway with  typeset  and  similar  state-
              ments.

              This option respects the setting of the KSH_TYPESET option.  In other words,
              if both options are in effect, arguments looking like assignments  will  not
              undergo word splitting.

       MARK_DIRS (-8, ksh: -X)
              Append a trailing '/' to all directory names resulting from filename genera-
              tion (globbing).

       MULTIBYTE <C> <K> <Z>
              Respect multibyte characters when found in strings.   When  this  option  is
              set,  strings  are  examined  using the system library to determine how many
              bytes form a character, depending on the current locale.  This  affects  the
              way characters are counted in pattern matching, parameter values and various
              delimiters.

              The option is on by default if the shell was compiled with MULTIBYTE_SUPPORT
              except  in sh emulation; otherwise it is off by default and has no effect if
              turned on.  The mode is off in sh emulation for compatibility but for inter-
              active  use  may  need  to be turned on if the terminal interprets multibyte
              characters.

              If the option is off a single byte is always treated as a single  character.
              This  setting  is designed purely for examining strings known to contain raw
              bytes or other values that may not be characters in the current locale.   It
              is  not  necessary  to unset the option merely because the character set for
              the current locale does not contain multibyte characters.

              The option does not affect the shell's editor,  which always uses the locale
              to  determine  multibyte characters.  This is because the character set dis-
              played by the terminal emulator is independent of shell settings.

       NOMATCH (+3) <C> <Z>
              If a pattern for filename generation has no matches, print an error, instead
              of  leaving  it  unchanged  in the argument list.  This also applies to file
              expansion of an initial '~' or '='.

       NULL_GLOB (-G)
              If a pattern for filename generation has no matches, delete the pattern from
              the argument list instead of reporting an error.  Overrides NOMATCH.

       NUMERIC_GLOB_SORT
              If  numeric filenames are matched by a filename generation pattern, sort the
              filenames numerically rather than lexicographically.

       RC_EXPAND_PARAM (-P)
              Array expansions of the form 'foo${xx}bar', where the parameter xx is set to
              (a  b  c),  are  substituted  with  'fooabar foobbar foocbar' instead of the
              default 'fooa b cbar'.  Note that an empty array will  therefore  cause  all
              arguments to be removed.

       REMATCH_PCRE <Z>
              If  set, regular expression matching with the =~ operator will use Perl-Com-
              patible Regular Expressions from the PCRE library,  if  available.   If  not
              set, regular expressions will use the extended regexp syntax provided by the
              system libraries.

       SH_GLOB <K> <S>
              Disables the special meaning of '(', '|',  ')'  and  '<'  for  globbing  the
              result  of  parameter  and  command  substitutions, and in some other places
              where the shell accepts patterns.  If SH_GLOB is set but  KSH_GLOB  is  not,
              the  shell  allows  the  interpretation  of subshell expressions enclosed in
              parentheses in some cases where there is no space before the opening  paren-
              thesis,  e.g.  !(true)  is interpreted as if there were a space after the !.
              This option is set by default if zsh is invoked as sh or ksh.

       UNSET (+u, ksh: +u) <K> <S> <Z>
              Treat unset parameters as if they were empty when  substituting.   Otherwise
              they are treated as an error.

       WARN_CREATE_GLOBAL
              Print  a warning message when a global parameter is created in a function by
              an assignment.  This often indicates that a parameter has not been  declared
              local  when it should have been.  Parameters explicitly declared global from
              within a function using typeset -g do not cause a warning.  Note that  there
              is  no  warning  when a local parameter is assigned to in a nested function,
              which may also indicate an error.


   History
       APPEND_HISTORY <D>
              If this is set, zsh sessions will append their history list to  the  history
              file,  rather than replace it. Thus, multiple parallel zsh sessions will all
              have the new entries from their history lists added to the history file,  in
              the order that they exit.  The file will still be periodically re-written to
              trim it when the number of lines grows 20% beyond  the  value  specified  by
              $SAVEHIST (see also the HIST_SAVE_BY_COPY option).

       BANG_HIST (+K) <C> <Z>
              Perform  textual  history  expansion,  csh-style, treating the character '!'
              specially.

       EXTENDED_HISTORY <C>
              Save each command's beginning timestamp (in seconds since the epoch) and the
              duration (in seconds) to the history file.  The format of this prefixed data
              is:

              ': <beginning time>:<elapsed seconds>;<command>'.

       HIST_ALLOW_CLOBBER
              Add '|' to output redirections in the history.  This allows  history  refer-
              ences to clobber files even when CLOBBER is unset.

       HIST_BEEP <D>
              Beep when an attempt is made to access a history entry which isn't there.

       HIST_EXPIRE_DUPS_FIRST
              If the internal history needs to be trimmed to add the current command line,
              setting this option will cause the oldest history event that has a duplicate
              to  be  lost before losing a unique event from the list.  You should be sure
              to set the value of HISTSIZE to a larger number than SAVEHIST  in  order  to
              give  you  some  room  for the duplicated events, otherwise this option will
              behave just like HIST_IGNORE_ALL_DUPS once the history fills up with  unique
              events.

       HIST_FCNTL_LOCK
              When  writing  out the history file, by default zsh uses ad-hoc file locking
              to avoid known problems with locking on some operating systems.   With  this
              option  locking  is  done  by  means  of the system's fcntl call, where this
              method is available.  On recent operating systems this  may  provide  better
              performance, in particular avoiding history corruption when files are stored
              on NFS.

       HIST_FIND_NO_DUPS
              When searching for history entries in the line editor, do not display dupli-
              cates of a line previously found, even if the duplicates are not contiguous.

       HIST_IGNORE_ALL_DUPS
              If a new command line being added to the history list  duplicates  an  older
              one,  the older command is removed from the list (even if it is not the pre-
              vious event).

       HIST_IGNORE_DUPS (-h)
              Do not enter command lines into the history list if they are  duplicates  of
              the previous event.

       HIST_IGNORE_SPACE (-g)
              Remove  command  lines from the history list when the first character on the
              line is a space, or when one of the  expanded  aliases  contains  a  leading
              space.   Only  normal  aliases  (not  global  or  suffix  aliases) have this
              behaviour.  Note that the command lingers in the internal history until  the
              next command is entered before it vanishes, allowing you to briefly reuse or
              edit the line.  If you want to make it vanish right  away  without  entering
              another command, type a space and press return.

       HIST_LEX_WORDS
              By  default, shell history that is read in from files is split into words on
              all white space.  This means that arguments with quoted whitespace  are  not
              correctly  handled, with the consequence that references to words in history
              lines that have been read from a file may be inaccurate.  When  this  option
              is  set, words read in from a history file are divided up in a similar fash-
              ion to normal shell command line  handling.   Although  this  produces  more
              accurately  delimited  words,  if the size of the history file is large this
              can be slow.  Trial and error is necessary to decide.

       HIST_NO_FUNCTIONS
              Remove function definitions from the history list.  Note that  the  function
              lingers  in the internal history until the next command is entered before it
              vanishes, allowing you to briefly reuse or edit the definition.

       HIST_NO_STORE
              Remove the history (fc -l) command from the history list when invoked.  Note
              that  the  command lingers in the internal history until the next command is
              entered before it vanishes, allowing you to briefly reuse or edit the  line.

       HIST_REDUCE_BLANKS
              Remove  superfluous blanks from each command line being added to the history
              list.

       HIST_SAVE_BY_COPY <D>
              When the history file is re-written, we normally write out  a  copy  of  the
              file  named  $HISTFILE.new and then rename it over the old one.  However, if
              this option is unset, we instead truncate the old history file and write out
              the  new  version  in-place.   If  one  of  the history-appending options is
              enabled, this option only has an effect when the enlarged history file needs
              to  be  re-written  to  trim it down to size.  Disable this only if you have
              special needs, as doing so makes it possible to lose history entries if  zsh
              gets interrupted during the save.

              When  writing  out  a copy of the history file, zsh preserves the old file's
              permissions and group information, but will refuse to write out a  new  file
              if it would change the history file's owner.

       HIST_SAVE_NO_DUPS
              When  writing out the history file, older commands that duplicate newer ones
              are omitted.

       HIST_VERIFY
              Whenever the user enters a line with history expansion,  don't  execute  the
              line  directly;  instead, perform history expansion and reload the line into
              the editing buffer.

       INC_APPEND_HISTORY
              This options works like APPEND_HISTORY except that  new  history  lines  are
              added  to  the $HISTFILE incrementally (as soon as they are entered), rather
              than waiting until the shell exits.  The file  will  still  be  periodically
              re-written  to  trim  it when the number of lines grows 20% beyond the value
              specified by $SAVEHIST (see also the HIST_SAVE_BY_COPY option).

       SHARE_HISTORY <K>

              This option both imports new commands from the history file, and also causes
              your  typed  commands to be appended to the history file (the latter is like
              specifying INC_APPEND_HISTORY).  The history  lines  are  also  output  with
              timestamps  ala  EXTENDED_HISTORY  (which  makes  it easier to find the spot
              where we left off reading the file after it gets re-written).

              By default, history movement commands visit the imported lines  as  well  as
              the  local lines, but you can toggle this on and off with the set-local-his-
              tory zle binding.  It is also possible to create a zle widget that will make
              some commands ignore imported commands, and some include them.

              If  you find that you want more control over when commands get imported, you
              may wish to turn SHARE_HISTORY off, INC_APPEND_HISTORY on, and then manually
              import commands whenever you need them using 'fc -RI'.


   Initialisation
       ALL_EXPORT (-a, ksh: -a)
              All parameters subsequently defined are automatically exported.

       GLOBAL_EXPORT (<Z>)
              If  this  option is set, passing the -x flag to the builtins declare, float,
              integer, readonly and typeset (but not local) will also  set  the  -g  flag;
              hence  parameters  exported to the environment will not be made local to the
              enclosing function, unless they  were  already  or  the  flag  +g  is  given
              explicitly.   If the option is unset, exported parameters will be made local
              in just the same way as any other parameter.

              This option is set by default for backward compatibility; it is  not  recom-
              mended  that  its  behaviour  be  relied upon.  Note that the builtin export
              always sets both the -x and -g flags, and hence its  effect  extends  beyond
              the  scope  of  the  enclosing  function;  this  is the most portable way to
              achieve this behaviour.

       GLOBAL_RCS (-d) <D>
              If this option  is  unset,  the  startup  files  /etc/zprofile,  /etc/zshrc,
              /etc/zlogin  and  /etc/zlogout  will  not  be  run.   It can be disabled and
              re-enabled at any time, including inside local startup files (.zshrc, etc.).

       RCS (+f) <D>
              After  /etc/zshenv is sourced on startup, source the .zshenv, /etc/zprofile,
              .zprofile, /etc/zshrc, .zshrc, /etc/zlogin, .zlogin, and .zlogout files,  as
              described  in the section 'Files'.  If this option is unset, the /etc/zshenv
              file is still sourced, but any of the others will not be; it can be  set  at
              any  time to prevent the remaining startup files after the currently execut-
              ing one from being sourced.


   Input/Output
       ALIASES <D>
              Expand aliases.

       CLOBBER (+C, ksh: +C) <D>
              Allows '>' redirection to truncate existing files, and '>>' to create files.
              Otherwise  '>!'  or '>|' must be used to truncate a file, and '>>!' or '>>|'
              to create a file.

       CORRECT (-0)
              Try to correct the spelling of commands.  Note that, when the  HASH_LIST_ALL
              option  is  not  set  or when some directories in the path are not readable,
              this may falsely report spelling errors the first  time  some  commands  are
              used.

              The  shell  variable  CORRECT_IGNORE  may be set to a pattern to match words
              that will never be offered as corrections.

       CORRECT_ALL (-O)
              Try to correct the spelling of all arguments in a line.

       DVORAK Use the Dvorak keyboard instead of the standard qwerty keyboard as  a  basis
              for  examining spelling mistakes for the CORRECT and CORRECT_ALL options and
              the spell-word editor command.

       FLOW_CONTROL <D>
              If this option is unset, output flow control via start/stop characters (usu-
              ally assigned to ^S/^Q) is disabled in the shell's editor.

       IGNORE_EOF (-7)
              Do  not  exit  on  end-of-file.   Require the use of exit or logout instead.
              However, ten consecutive EOFs will cause the shell to exit anyway, to  avoid
              the shell hanging if its tty goes away.

              Also,  if this option is set and the Zsh Line Editor is used, widgets imple-
              mented by shell functions can be bound to EOF (normally  Control-D)  without
              printing  the  normal  warning message.  This works only for normal widgets,
              not for completion widgets.

       INTERACTIVE_COMMENTS (-k) <K> <S>
              Allow comments even in interactive shells.

       HASH_CMDS <D>
              Note the location of each command the first time it is executed.  Subsequent
              invocations of the same command will use the saved location, avoiding a path
              search.  If this option is unset, no path hashing is done at all.   However,
              when  CORRECT is set, commands whose names do not appear in the functions or
              aliases hash tables are hashed in order to avoid reporting them as  spelling
              errors.

       HASH_DIRS <D>
              Whenever a command name is hashed, hash the directory containing it, as well
              as all directories that occur earlier in the path.  Has no effect if neither
              HASH_CMDS nor CORRECT is set.

       MAIL_WARNING (-U)
              Print  a  warning  message  if a mail file has been accessed since the shell
              last checked.

       PATH_DIRS (-Q)
              Perform a path search even on command names with slashes in them.   Thus  if
              '/usr/local/bin' is in the user's path, and he or she types 'X11/xinit', the
              command '/usr/local/bin/X11/xinit' will be executed  (assuming  it  exists).
              Commands explicitly beginning with '/', './' or '../' are not subject to the
              path search.  This also applies to the '.' builtin.

              Note that subdirectories of the current directory are  always  searched  for
              executables  specified  in  this  form.   This takes place before any search
              indicated by this option, and regardless  of  whether  '.'  or  the  current
              directory appear in the command search path.

       PATH_SCRIPT <K> <S>
              If  this option is not set, a script passed as the first non-option argument
              to the shell must contain the name of the file to open.  If this  option  is
              set,  and the script does not specify a directory path, the script is looked
              for first in the current directory, then in the command path.  See the  sec-
              tion INVOCATION in zsh(1).

       PRINT_EIGHT_BIT
              Print  eight bit characters literally in completion lists, etc.  This option
              is not necessary if your system correctly returns the printability of  eight
              bit characters (see ctype(3)).

       PRINT_EXIT_VALUE (-1)
              Print the exit value of programs with non-zero exit status.

       RC_QUOTES
              Allow  the  character  sequence '''' to signify a single quote within singly
              quoted strings.  Note this does not apply in quoted strings using the format
              $'...', where a backslashed single quote can be used.

       RM_STAR_SILENT (-H) <K> <S>
              Do not query the user before executing 'rm *' or 'rm path/*'.

       RM_STAR_WAIT
              If  querying the user before executing 'rm *' or 'rm path/*', first wait ten
              seconds and ignore anything typed in that time.  This avoids the problem  of
              reflexively  answering  'yes'  to  the query when one didn't really mean it.
              The wait and query can always be avoided by expanding the '*' in  ZLE  (with
              tab).

       SHORT_LOOPS <C> <Z>
              Allow the short forms of for, repeat, select, if, and function constructs.

       SUN_KEYBOARD_HACK (-L)
              If  a  line ends with a backquote, and there are an odd number of backquotes
              on the line, ignore the trailing backquote.  This is  useful  on  some  key-
              boards  where the return key is too small, and the backquote key lies annoy-
              ingly close to it.  As an alternative the variable  KEYBOARD_HACK  lets  you
              choose the character to be removed.


   Job Control
       AUTO_CONTINUE
              With  this option set, stopped jobs that are removed from the job table with
              the disown builtin command are automatically sent a CONT signal to make them
              running.

       AUTO_RESUME (-W)
              Treat  single  word  simple  commands  without redirection as candidates for
              resumption of an existing job.

       BG_NICE (-6) <C> <Z>
              Run all background jobs at a lower priority.  This option is set by default.

       CHECK_JOBS <Z>
              Report  the  status  of background and suspended jobs before exiting a shell
              with job  control;  a  second  attempt  to  exit  the  shell  will  succeed.
              NO_CHECK_JOBS  is  best used only in combination with NO_HUP, else such jobs
              will be killed automatically.

              The check is omitted if the commands run  from  the  previous  command  line
              included  a 'jobs' command, since it is assumed the user is aware that there
              are background or suspended jobs.  A 'jobs' command run from one of the hook
              functions  defined  in  the  section  SPECIAL FUNCTIONS in zshmisc(1) is not
              counted for this purpose.

       HUP <Z>
              Send the HUP signal to running jobs when the shell exits.

       LONG_LIST_JOBS (-R)
              List jobs in the long format by default.

       MONITOR (-m, ksh: -m)
              Allow job control.  Set by default in interactive shells.

       NOTIFY (-5, ksh: -b) <Z>
              Report the status of background jobs immediately, rather than waiting  until
              just before printing a prompt.

       POSIX_JOBS <K> <S>
              This option makes job control more compliant with the POSIX standard.

              When  the  option  is  not set, the MONITOR option is unset on entry to sub-
              shells, so that job control is no longer active.  When the  option  is  set,
              the  MONITOR  option and job control remain active in the subshell, but note
              that the subshell has no access to jobs in the parent shell.

              When the option is not set, jobs put in the background or foreground with bg
              or  fg  are  displayed  with  the same information that would be reported by
              jobs.  When the option is set, only the text is printed.   The  output  from
              jobs itself is not affected by the option.

              When  the  option is not set, job information from the parent shell is saved
              for output within a subshell (for example, within  a  pipeline).   When  the
              option is set, the output of jobs is empty until a job is started within the
              subshell.

              When the option is set, it becomes possible to use the wait builtin to  wait
              for the last job started in the background (as given by $!) even if that job
              has already exited.  This works even if the option is turned on  temporarily
              around the use of the wait builtin.


   Prompting
       PROMPT_BANG <K>
              If  set,  '!'  is  treated  specially in prompt expansion.  See EXPANSION OF
              PROMPT SEQUENCES in zshmisc(1).

       PROMPT_CR (+V) <D>
              Print a carriage return just before printing a prompt in  the  line  editor.
              This  is  on by default as multi-line editing is only possible if the editor
              knows where the start of the line appears.

       PROMPT_SP <D>
              Attempt to preserve a partial line (i.e. a line that did not end with a new-
              line)  that  would  otherwise be covered up by the command prompt due to the
              PROMPT_CR option.  This works by outputting some cursor-control  characters,
              including a series of spaces, that should make the terminal wrap to the next
              line when a partial line is present (note that this is  only  successful  if
              your terminal has automatic margins, which is typical).

              When  a  partial  line is preserved, by default you will see an inverse+bold
              character at the end of the partial line:  a "%" for a normal user or a  "#"
              for  root.   If set, the shell parameter PROMPT_EOL_MARK can be used to cus-
              tomize how the end of partial lines are shown.

              NOTE: if the PROMPT_CR option is not set, enabling this option will have  no
              effect.  This option is on by default.

       PROMPT_PERCENT <C> <Z>
              If  set,  '%'  is  treated  specially in prompt expansion.  See EXPANSION OF
              PROMPT SEQUENCES in zshmisc(1).

       PROMPT_SUBST <K> <S>
              If set, parameter expansion, command substitution and  arithmetic  expansion
              are  performed  in  prompts.  Substitutions within prompts do not affect the
              command status.

       TRANSIENT_RPROMPT
              Remove any right prompt from display when accepting a  command  line.   This
              may be useful with terminals with other cut/paste methods.


   Scripts and Functions
       C_BASES
              Output  hexadecimal  numbers  in  the  standard C format, for example '0xFF'
              instead of the usual '16#FF'.  If the option OCTAL_ZEROES is also set (it is
              not by default), octal numbers will be treated similarly and hence appear as
              '077' instead of '8#77'.  This option has no effect on  the  choice  of  the
              output  base,  nor  on the output of bases other than hexadecimal and octal.
              Note that these formats will be understood on input irrespective of the set-
              ting of C_BASES.

       C_PRECEDENCES
              This  alters  the  precedence  of arithmetic operators to be more like C and
              other programming languages; the section ARITHMETIC EVALUATION in zshmisc(1)
              has an explicit list.

       DEBUG_BEFORE_CMD
              Run  the DEBUG trap before each command; otherwise it is run after each com-
              mand.  Setting this option mimics the behaviour of ksh 93; with  the  option
              unset the behaviour is that of ksh 88.

       ERR_EXIT (-e, ksh: -e)
              If  a command has a non-zero exit status, execute the ZERR trap, if set, and
              exit.  This is disabled while running initialization scripts.

              The behaviour is also disabled inside DEBUG traps.  In this case the  option
              is  handled  specially:  it  is  unset  on entry to the trap.  If the option
              DEBUG_BEFORE_CMD is set, as it is by default, and  the  option  ERR_EXIT  is
              found to have been set on exit, then the command for which the DEBUG trap is
              being executed is skipped.  The option is restored after the trap exits.

       ERR_RETURN
              If a command has a non-zero exit status, return immediately from the enclos-
              ing  function.   The logic is identical to that for ERR_EXIT, except that an
              implicit return statement is executed instead of an exit.  This will trigger
              an exit at the outermost level of a non-interactive script.

       EVAL_LINENO <Z>
              If  set,  line  numbers  of expressions evaluated using the builtin eval are
              tracked separately of the enclosing environment.  This applies both  to  the
              parameter LINENO and the line number output by the prompt escape %i.  If the
              option is set, the prompt escape %N will output the string '(eval)'  instead
              of  the  script or function name as an indication.   (The two prompt escapes
              are typically used in the parameter PS4 to be output when the option  XTRACE
              is set.)  If EVAL_LINENO is unset, the line number of the surrounding script
              or function is retained during the evaluation.

       EXEC (+n, ksh: +n) <D>
              Do execute commands.  Without this option, commands are read and checked for
              syntax  errors,  but  not  executed.  This option cannot be turned off in an
              interactive shell, except when '-n' is supplied to the shell at startup.

       FUNCTION_ARGZERO <C> <Z>
              When executing a shell function or sourcing a script, set $0 temporarily  to
              the name of the function/script.

       LOCAL_OPTIONS <K>
              If  this  option  is  set at the point of return from a shell function, most
              options (including this one) which were in force upon entry to the  function
              are  restored;  options that are not restored are PRIVILEGED and RESTRICTED.
              Otherwise, only this option and the XTRACE and PRINT_EXIT_VALUE options  are
              restored.   Hence  if this is explicitly unset by a shell function the other
              options in force at the point of return will remain so.   A  shell  function
              can  also  guarantee  itself  a known shell configuration with a formulation
              like 'emulate -L zsh'; the -L activates LOCAL_OPTIONS.

       LOCAL_TRAPS <K>
              If this option is set when a signal trap is set inside a function, then  the
              previous  status of the trap for that signal will be restored when the func-
              tion exits.  Note that this option must be set prior to  altering  the  trap
              behaviour  in  a  function; unlike LOCAL_OPTIONS, the value on exit from the
              function is irrelevant.  However, it does not need  to  be  set  before  any
              global trap for that to be correctly restored by a function.  For example,

                     unsetopt localtraps
                     trap - INT
                     fn() { setopt localtraps; trap '' INT; sleep 3; }

              will restore normal handling of SIGINT after the function exits.

       MULTI_FUNC_DEF <Z>
              Allow  definitions of multiple functions at once in the form 'fn1 fn2...()';
              if the option is not set, this causes a parse error.  Definition of multiple
              functions  with  the  function keyword is always allowed.  Multiple function
              definitions are not often used and can cause obscure errors.

       MULTIOS <Z>
              Perform implicit tees or cats when multiple redirections are attempted  (see
              the section 'Redirection').

       OCTAL_ZEROES <S>
              Interpret  any  integer  constant  beginning with a 0 as octal, per IEEE Std
              1003.2-1992 (ISO 9945-2:1993).  This is not enabled by default as it  causes
              problems  with  parsing  of, for example, date and time strings with leading
              zeroes.

              Sequences of digits indicating a numeric base such as the '08' component  in
              '08#77' are always interpreted as decimal, regardless of leading zeroes.

       SOURCE_TRACE
              If  set, zsh will print an informational message announcing the name of each
              file it loads.  The format of the output is similar to that for  the  XTRACE
              option,  with  the message <sourcetrace>.  A file may be loaded by the shell
              itself when it starts up and shuts down (Startup/Shutdown Files) or  by  the
              use of the 'source' and 'dot' builtin commands.

       TYPESET_SILENT
              If  this is unset, executing any of the 'typeset' family of commands with no
              options and a list of parameters that have no  values  to  be  assigned  but
              already  exist  will  display  the value of the parameter.  If the option is
              set, they will only be shown when parameters  are  selected  with  the  '-m'
              option.  The option '-p' is available whether or not the option is set.

       VERBOSE (-v, ksh: -v)
              Print shell input lines as they are read.

       XTRACE (-x, ksh: -x)
              Print commands and their arguments as they are executed.  The output is pro-
              ceded by the value of $PS4, formatted as described in the section  EXPANSION
              OF PROMPT SEQUENCES in zshmisc(1).


   Shell Emulation
       BASH_REMATCH
              When  set,  matches performed with the =~ operator will set the BASH_REMATCH
              array variable, instead of the default MATCH and match variables.  The first
              element  of  the BASH_REMATCH array will contain the entire matched text and
              subsequent elements will contain extracted substrings.   This  option  makes
              more  sense  when KSH_ARRAYS is also set, so that the entire matched portion
              is stored at index 0 and the first substring is at index  1.   Without  this
              option,  the  MATCH  variable contains the entire matched text and the match
              array variable contains substrings.

       BSD_ECHO <S>
              Make the echo builtin compatible with the BSD echo(1)  command.   This  dis-
              ables  backslashed  escape sequences in echo strings unless the -e option is
              specified.

       CSH_JUNKIE_HISTORY <C>
              A history reference without an event specifier will always refer to the pre-
              vious  command.  Without this option, such a history reference refers to the
              same event as the previous history reference,  defaulting  to  the  previous
              command.

       CSH_JUNKIE_LOOPS <C>
              Allow loop bodies to take the form 'list; end' instead of 'do list; done'.

       CSH_JUNKIE_QUOTES <C>
              Changes  the  rules for single- and double-quoted text to match that of csh.
              These require that embedded newlines be preceded by a  backslash;  unescaped
              newlines  will cause an error message.  In double-quoted strings, it is made
              impossible to escape '$', ''' or '"' (and '\' itself no longer needs  escap-
              ing).  Command substitutions are only expanded once, and cannot be nested.

       CSH_NULLCMD <C>
              Do  not  use the values of NULLCMD and READNULLCMD when running redirections
              with no command.  This make such redirections fail (see the  section  'Redi-
              rection').

       KSH_ARRAYS <K> <S>
              Emulate  ksh  array handling as closely as possible.  If this option is set,
              array elements are numbered from zero, an array parameter without  subscript
              refers  to  the  first  element  instead  of the whole array, and braces are
              required to delimit a subscript ('${path[2]}' rather than just  '$path[2]').

       KSH_AUTOLOAD <K> <S>
              Emulate  ksh  function  autoloading.   This  means  that  when a function is
              autoloaded, the corresponding file is merely executed, and must  define  the
              function  itself.   (By  default, the function is defined to the contents of
              the file.  However, the most common ksh-style case - of the file  containing
              only a simple definition of the function - is always handled in the ksh-com-
              patible manner.)

       KSH_OPTION_PRINT <K>
              Alters the way options settings are printed: instead of  separate  lists  of
              set and unset options, all options are shown, marked 'on' if they are in the
              non-default state, 'off' otherwise.

       KSH_TYPESET <K>
              Alters the way arguments  to  the  typeset  family  of  commands,  including
              declare, export, float, integer, local and readonly, are processed.  Without
              this option, zsh will perform normal word splitting after command and param-
              eter  expansion  in arguments of an assignment; with it, word splitting does
              not take place in those cases.

       KSH_ZERO_SUBSCRIPT
              Treat use of a subscript of value zero in array or string expressions  as  a
              reference  to  the  first  element,  i.e.  the  element that usually has the
              subscript 1.  Ignored if KSH_ARRAYS is also set.

              If neither this option nor KSH_ARRAYS is set, accesses to an element  of  an
              array or string with subscript zero return an empty element or string, while
              attempts to set element zero of an array or string are treated as an  error.
              However,  attempts  to  set an otherwise valid subscript range that includes
              zero will succeed.  For example, if KSH_ZERO_SUBSCRIPT is not set,

                     array[0]=(element)

              is an error, while

                     array[0,1]=(element)

              is not and will replace the first element of the array.

              This option is for compatibility with older versions of the shell and is not
              recommended in new code.

       POSIX_ALIASES <K> <S>
              When  this option is set, reserved words are not candidates for alias expan-
              sion:  it is still possible to declare any of them  as  an  alias,  but  the
              alias  will  never be expanded.  Reserved words are described in the section
              RESERVED WORDS in zshmisc(1).

              Alias expansion takes place while text is being read; hence when this option
              is  set it does not take effect until the end of any function or other piece
              of shell code parsed as one unit.  Note  this  may  cause  differences  from
              other shells even when the option is in effect.  For example, when running a
              command with 'zsh -c', or even 'zsh -o posixaliases -c', the entire  command
              argument  is  parsed as one unit, so aliases defined within the argument are
              not available even in later lines.  If in doubt, avoid  use  of  aliases  in
              non-interactive code.

       POSIX_BUILTINS <K> <S>
              When  this  option  is  set the command builtin can be used to execute shell
              builtin commands.  Parameter assignments specified  before  shell  functions
              and special builtins are kept after the command completes unless the special
              builtin is prefixed with the command builtin.  Special builtins  are  .,  :,
              break,  continue,  declare,  eval,  exit,  export, integer, local, readonly,
              return, set, shift, source, times, trap and unset.

              In addition, various error conditions associated with the above builtins  or
              exec  cause  a  non-interactive  shell  to  exit and an interactive shell to
              return to its top-level processing.

       POSIX_IDENTIFIERS <K> <S>
              When this option is set, only the ASCII characters a to z, A to Z,  0  to  9
              and _ may be used in identifiers (names of shell parameters and modules).

              When the option is unset and multibyte character support is enabled (i.e. it
              is compiled in and the option  MULTIBYTE  is  set),  then  additionally  any
              alphanumeric  characters  in  the local character set may be used in identi-
              fiers.  Note that scripts and functions written with this  feature  are  not
              portable,  and also that both options must be set before the script or func-
              tion is parsed; setting them during execution is not sufficient as the  syn-
              tax  variable=value  has  already  been  parsed  as a command rather than an
              assignment.

              If multibyte character support is not compiled into the shell this option is
              ignored;  all  octets with the top bit set may be used in identifiers.  This
              is non-standard but is the traditional zsh behaviour.

       POSIX_STRINGS <K> <S>
              This option affects processing of quoted strings.  Currently it only affects
              the behaviour of null characters, i.e. character 0 in the portable character
              set corresponding to US ASCII.

              When this option is not set, null characters embedded within strings of  the
              form  $'...'  are treated as ordinary characters. The entire string is main-
              tained within the shell and output to files where necessary, although  owing
              to restrictions of the library interface the string is truncated at the null
              character in file names, environment variables, or in arguments to  external
              programs.

              When  this  option  is  set,  the $'...' expression is truncated at the null
              character.  Note that remaining parts of the same string beyond the termina-
              tion of the quotes are not trunctated.

              For  example, the command line argument a$'b\0c'd is treated with the option
              off as the characters a, b, null, c, d, and with the option on as the  char-
              acters a, b, d.

       POSIX_TRAPS <K> <S>
              When  the  is  option is set, the usual zsh behaviour of executing traps for
              EXIT on exit from shell functions is suppressed.  In that case, manipulating
              EXIT  traps  always  alters  the  global  trap  for  exiting  the shell; the
              LOCAL_TRAPS option is ignored for the EXIT trap.

       SH_FILE_EXPANSION <K> <S>
              Perform filename expansion (e.g., ~ expansion) before  parameter  expansion,
              command  substitution,  arithmetic  expansion  and brace expansion.  If this
              option is unset, it is performed  after  brace  expansion,  so  things  like
              '~$USERNAME' and '~{pfalstad,rc}' will work.

       SH_NULLCMD <K> <S>
              Do  not  use  the values of NULLCMD and READNULLCMD when doing redirections,
              use ':' instead (see the section 'Redirection').

       SH_OPTION_LETTERS <K> <S>
              If this option is set the shell tries to  interpret  single  letter  options
              (which  are  used with set and setopt) like ksh does.  This also affects the
              value of the - special parameter.

       SH_WORD_SPLIT (-y) <K> <S>
              Causes field splitting to be performed  on  unquoted  parameter  expansions.
              Note  that this option has nothing to do with word splitting.  (See the sec-
              tion 'Parameter Expansion'.)

       TRAPS_ASYNC
              While waiting for a program to exit, handle signals and  run  traps  immedi-
              ately.   Otherwise  the  trap is run after a child process has exited.  Note
              this does not affect the point at which traps are run  for  any  case  other
              than when the shell is waiting for a child process.


   Shell State
       INTERACTIVE (-i, ksh: -i)
              This is an interactive shell.  This option is set upon initialisation if the
              standard input is a tty and commands are being  read  from  standard  input.
              (See  the  discussion  of  SHIN_STDIN.)  This heuristic may be overridden by
              specifying a state for this option on the command line.  The value  of  this
              option  can  only  be changed via flags supplied at invocation of the shell.
              It cannot be changed once zsh is running.

       LOGIN (-l, ksh: -l)
              This is a login shell.  If this option is  not  explicitly  set,  the  shell
              becomes  a  login  shell if the first character of the argv[0] passed to the
              shell is a '-'.

       PRIVILEGED (-p, ksh: -p)
              Turn on privileged mode. This is enabled automatically  on  startup  if  the
              effective user (group) ID is not equal to the real user (group) ID.  Turning
              this option off causes the effective user and group IDs to  be  set  to  the
              real  user  and group IDs. This option disables sourcing user startup files.
              If zsh is invoked as 'sh' or 'ksh' with this option  set,  /etc/suid_profile
              is  sourced  (after /etc/profile on interactive shells). Sourcing ~/.profile
              is disabled and the contents of the ENV variable  is  ignored.  This  option
              cannot  be  changed using the -m option of setopt and unsetopt, and changing
              it  inside  a  function  always  changes  it  globally  regardless  of   the
              LOCAL_OPTIONS option.

       RESTRICTED (-r)
              Enables  restricted mode.  This option cannot be changed using unsetopt, and
              setting it inside a function always changes it globally  regardless  of  the
              LOCAL_OPTIONS option.  See the section 'Restricted Shell'.

       SHIN_STDIN (-s, ksh: -s)
              Commands  are  being  read  from the standard input.  Commands are read from
              standard input if no command is specified with -c and no file of commands is
              specified.   If  SHIN_STDIN is set explicitly on the command line, any argu-
              ment that would otherwise have been taken as a file to run will  instead  be
              treated  as  a  normal positional parameter.  Note that setting or unsetting
              this option on the command line does not necessarily affect  the  state  the
              option will have while the shell is running - that is purely an indicator of
              whether on not commands are actually being read from  standard  input.   The
              value of this option can only be changed via flags supplied at invocation of
              the shell.  It cannot be changed once zsh is running.

       SINGLE_COMMAND (-t, ksh: -t)
              If the shell is reading from standard input, it exits after a single command
              has  been  executed.   This also makes the shell non-interactive, unless the
              INTERACTIVE option is explicitly set on the command line.  The value of this
              option  can  only  be changed via flags supplied at invocation of the shell.
              It cannot be changed once zsh is running.


   Zle
       BEEP (+B) <D>
              Beep on error in ZLE.

       COMBINING_CHARS
              Assume that the terminal displays combining characters correctly.   Specifi-
              cally,  if  a  base  alphanumeric  character  is  followed  by  one  or more
              zero-width punctuation characters, assume  that  the  zero-width  characters
              will  be  displayed  as  modifications to the base character within the same
              width.  Not  all  terminals  handle  this.   If  this  option  is  not  set,
              zero-width characters are displayed separately with special mark-up.

              If  this  option  is  set,  the pattern test [[:WORD:]] matches a zero-width
              punctuation character on the assumption that it will be used as  part  of  a
              word  in  combination  with a word character.  Otherwise the base shell does
              not handle combining characters specially.

       EMACS  If ZLE is loaded, turning on this option has the equivalent effect of 'bind-
              key  -e'.   In  addition,  the  VI  option  is unset.  Turning it off has no
              effect.  The option setting is not guaranteed to reflect the current keymap.
              This option is provided for compatibility; bindkey is the recommended inter-
              face.

       OVERSTRIKE
              Start up the line editor in overstrike mode.

       SINGLE_LINE_ZLE (-M) <K>
              Use single-line command line editing instead of multi-line.

              Note that although this is on by default in ksh emulation it  only  provides
              superficial  compatibility  with  the ksh line editor and reduces the effec-
              tiveness of the zsh line editor.  As it has no effect on shell syntax,  many
              users  may  wish  to  disable  this option when using ksh emulation interac-
              tively.

       VI     If ZLE is loaded, turning on this option has the equivalent effect of 'bind-
              key  -v'.   In  addition,  the EMACS option is unset.  Turning it off has no
              effect.  The option setting is not guaranteed to reflect the current keymap.
              This option is provided for compatibility; bindkey is the recommended inter-
              face.

       ZLE (-Z)
              Use the zsh line editor.  Set by default in interactive shells connected  to
              a terminal.
