       zshoptions - zsh options


       Options are primarily referred to by name.  These names are case insen-
       sitive and underscores are ignored.  For example, `allexport' is equiv-
       alent 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'.  Sim-
       ilarly, `tify' is not  a  synonym  for  `nonotify'  (the  inversion  of

       Some  options also have one or more single letter names.  There are two
       sets of single 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 implement the `#!' mechanism for calling
       scripts do not strip trailing whitespace.


       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 emula-
       tions 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  com-
              mand, and the command is the name of a directory, perform the cd
              command to that directory.

       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 Expansion').

              When  changing  to  a  directory  containing a path segment `..'
              which would otherwise be treated as canceling the previous  seg-
              ment 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 direc-
              tory.  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.

              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  interac-
              tive  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.

              Don't push multiple copies of the same directory onto the direc-
              tory stack.

              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'.

              If  unset,  key functions that list completions try to return to
              the last prompt if given a numeric argument. If set these  func-
              tions try to return to the last prompt if given no numeric argu-

              If a completion is performed with the cursor within a word,  and
              a full completion 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 per-

       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.

              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 `~'.  (Oth-
              erwise, the parameter must be used in the form `~param'  first.)

              If  a  parameter  name  was  completed and a following character
              (normally a space) automatically inserted, and the next  charac-
              ter  typed  is one of those that have to come directly after the
              name (like `}', `:', etc.), the automatically 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.

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

              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 amper-
              sand), remove the slash.

              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 immediately cycle
              through the list in that case.

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

              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.

              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  COMPLETE_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 con-
              tains a pattern; simply turning on the GLOB_COMPLETE option does
              not have this effect.

       HASH_LIST_ALL <D>
              Whenever   a   command  completion  or  spelling  correction  is
              attempted, make sure the entire command path  is  hashed  first.
              This  makes the first completion slower but avoids false reports
              of spelling errors.

              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  completion  widgets to return status 1 on an ambiguous com-
              pletion, which causes the shell to beep if the  option  BEEP  is
              also  set;  this  may be modified if completion is called from a
              user-defined widget.

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

              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.

              On an ambiguous completion, instead of listing possibilities  or
              beeping,  insert the first match immediately.  Then when comple-
              tion 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

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

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

              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'.

              Expand  expressions  in braces which would not otherwise undergo
              brace expansion to a lexically ordered list of all  the  charac-
              ters.  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 presence of any character which is spe-
              cial to filename generation will cause  case-insensitive  match-
              ing.   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  command  have  no  matches.   Overrides

       EQUALS <Z>
              Perform = filename expansion.  (See the section `Filename Expan-

              Treat the `#', `~' and `^' characters as part  of  patterns  for
              filename  generation, etc.  (An initial unquoted `~' always pro-
              duces named directory expansion.)

       GLOB (+F, ksh: +f) <D>
              Perform filename generation (globbing).  (See the section `File-
              name Generation'.)

       GLOB_ASSIGN <C>
              If  this  option  is set, filename generation (globbing) is per-
              formed 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 com-
              patibility 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 possible 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 explic-

       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.

              Substitutions  using  the  :s  and :& history modifiers are per-
              formed with pattern matching instead of string  matching.   This
              occurs  wherever  history  modifiers  are  valid, including glob
              qualifiers and parameters.  See the section  Modifiers  in  zsh-

       IGNORE_BRACES (-I) <S>
              Do  not  perform  brace  expansion.  For historical reasons this
              also includes the effect of the IGNORE_CLOSE_BRACES option.

              When neither this option nor IGNORE_BRACES is set, a sole  close
              brace character `}' is syntactically significant at any point on
              a command line.  This has the effect that no semicolon  or  new-
              line  is  necessary  before  the brace terminating a function or
              current shell construct.  When either option is set,  a  closing
              brace  is  syntactically  significant  only in command position.
              Unlike IGNORE_BRACES, this option does not disable brace  expan-

              For  example,  with both options unset a function may be defined
              in the following fashion:

                     args() { echo $# }

              while if either option is set, this does not work and  something
              equivalent to the following is required:

                     args() { echo $#; }

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

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

              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 generation (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 cur-
              rent  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 interactive 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  cur-
              rent 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 displayed 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.

              If numeric filenames are matched by a filename  generation  pat-
              tern,  sort  the filenames numerically rather than lexicographi-

              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.

              If  set,  regular  expression matching with the =~ operator will
              use Perl-Compatible 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  glob-
              bing  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 parenthesis, 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.

              Print a warning message when a global parameter is created in  a
              function  by an assignment.  This often indicates that a parame-
              ter 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 func-
              tion, which may also indicate an error.

              If this is set, zsh sessions will append their history  list  to
              the  history file, rather than replace it. Thus, multiple paral-
              lel zsh sessions will all have the new entries from  their  his-
              tory  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 char-
              acter `!' specially.

              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>'.

              Add `|' to output redirections in the history.  This allows his-
              tory references 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.

              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.

              When writing out the history file, by default  zsh  uses  ad-hoc
              file  locking to avoid known problems with locking on some oper-
              ating 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  par-
              ticular  avoiding  history  corruption  when files are stored on

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

              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 previous event).

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

              Remove  command lines from the history list when the first char-
              acter 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.

              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  conse-
              quence  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
              fashion 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 nec-
              essary to decide.

              Remove  function  definitions  from the history list.  Note that
              the function lingers in the internal history until the next com-
              mand  is entered before it vanishes, allowing you to briefly re-
              use or edit the definition.

              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.

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

              When the history file is re-written, we  normally  write  out  a
              copy of the file named $ 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 his-
              tory 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

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

              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.

              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  $SAVE-
              HIST (see also the HIST_SAVE_BY_COPY option).


              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_HIS-
              TORY  (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-history 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  when-
              ever you need them using `fc -RI'.

       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  recommended  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 func-
              tion; 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, .zlo-
              gin,  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.

       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.

              If  this  option  is  unset,  output flow control via start/stop
              characters (usually  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 implemented by shell functions can be bound to EOF (nor-
              mally  Control-D)  without  printing the normal warning message.
              This works only for normal widgets, not for completion  widgets.

              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, com-
              mands whose names do not appear in the functions or aliases hash
              tables are hashed in order to avoid reporting them  as  spelling

       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.

              When  hashing  commands because of HASH_COMMANDS, check that the
              file to be hashed is actually an  executable.   This  option  is
              unset  by default as if the path contains a large number of com-
              mands, or consists of many remote files,  the  additional  tests
              can take a long time.  Trial and error is needed to show if this
              option is beneficial.

       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  section
              INVOCATION in zsh(1).

              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.

              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 sin-
              gle quote can be used.

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

              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

              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 keyboards where the return key is too small, and
              the backquote key lies annoyingly close to it.  As  an  alterna-
              tive the variable KEYBOARD_HACK lets you choose the character to
              be removed.

   Job Control
              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  candi-
              dates 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  exit-
              ing 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 com-
              mand 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

       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

              When the option is not set, the MONITOR option is unset on entry
              to subshells, 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  fore-
              ground  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.

       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

       PROMPT_SP <D>
              Attempt to preserve a partial line (i.e. a line that did not end
              with a newline) that would otherwise be covered up by  the  com-
              mand  prompt  due  to  the PROMPT_CR option.  This works by out-
              putting 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 parame-
              ter PROMPT_EOL_MARK can be used to customize how the end of par-
              tial 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.

              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.

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

   Scripts and Functions
              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 setting of C_BASES.

              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.

              Run the DEBUG trap before each  command;  otherwise  it  is  run
              after each command.  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

              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  exe-
              cuted  is skipped.  The option is restored after the trap exits.

              If a command has a non-zero exit status, return immediately from
              the  enclosing  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  evalua-

       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 sup-
              plied to the shell at startup.

              When executing a shell function or sourcing  a  script,  set  $0
              temporarily to the name of the function/script.

              If  this option is set at the point of return from a shell func-
              tion, 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_TRAPS <K>
              If this option is set when a signal trap is set inside  a  func-
              tion,  then the previous status of the trap for that signal will
              be restored when the function 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.

              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').

              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, regard-
              less of leading zeroes.

              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.

              If  this is unset, executing any of the `typeset' family of com-
              mands with no options and a list of parameters that have no val-
              ues  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 proceded by the value of $PS4, formatted as described
              in the section EXPANSION OF PROMPT SEQUENCES in zshmisc(1).

   Shell Emulation
              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  disables  backslashed  escape  sequences  in  echo strings
              unless the -e option is specified.

              If a fatal error is encountered (see the section ERRORS in  zsh-
       misc(1)),  and  the  code is running in a script, the shell will
              resume execution at the next statement in the script at the  top
              level,  in other words outside all functions or shell constructs
              such as loops and conditions.   This  mimics  the  behaviour  of
              interactive  shells,  where the shell returns to the line editor
              to read a new command; it was the normal behaviour  in  versions
              of zsh before 5.0.1.

              A history reference without an event specifier will always refer
              to the previous command.  Without this option,  such  a  history
              reference  refers to the same event as the previous history ref-
              erence, defaulting to the previous command.

              Allow loop bodies to take the form `list; end'  instead  of  `do
              list; done'.

              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 escaping).  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 `Redirection').

       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 sub-
              script (`${path[2]}' rather than just `$path[2]').

       KSH_AUTOLOAD <K> <S>
              Emulate ksh function autoloading.  This means that when a  func-
              tion  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 com-
              mon ksh-style case - of the file containing only a simple  defi-
              nition of the function - is always handled in the ksh-compatible

              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 parameter expansion in argu-
              ments of an assignment; with it, word splitting  does  not  take
              place in those cases.

              Treat  use  of  a  subscript  of  value  zero in array or string
              expressions as a reference to the first element, i.e.  the  ele-
              ment 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,


              is an error, while


              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 expansion:  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.

              When  this option is set the command builtin can be used to exe-
              cute 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, con-
              tinue, 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.

              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 identifiers.  Note that scripts and
              functions  written  with this feature are not portable, and also
              that both options must be set before the script or  function  is
              parsed;  setting  them during execution is not sufficient as the
              syntax 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 tradi-
              tional 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 maintained 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 exter-
              nal programs.

              When this option is set, the $'...' expression is  truncated  at
              the  null  character.   Note  that  remaining  parts of the same
              string beyond the termination 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 characters 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.

              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

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

              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 section `Parameter Expansion'.)

              While waiting for a program to  exit,  handle  signals  and  run
              traps  immediately.   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 initiali-
              sation  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 effec-
              tive  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_pro-
              file 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

       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 sec-
              tion `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  explic-
              itly on the command line, any argument 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  can-
              not 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 can-
              not be changed once zsh is running.

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

              Assume that the  terminal  displays  combining  characters  cor-
              rectly.   Specifically, if a base alphanumeric character is fol-
              lowed by one or more zero-width punctuation  characters,  assume
              that  the  zero-width  characters will be displayed as modifica-
              tions to the base character within the same width.  Not all ter-
              minals handle this.  If this option is not set, zero-width char-
              acters 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

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

              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 effectiveness 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 interactively.

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

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


       Some  options have alternative names.  These aliases are never used for
       output, but can be used just like normal option names  when  specifying
       options to the shell.
