ZSHOPTIONS(1)                        General Commands Manual                        ZSHOPTIONS(1)



NAME
       zshoptions - zsh options

SPECIFYING OPTIONS
       Options  are  primarily  referred to by name.  These names are case insensitive and under-
       scores 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  inver-
       sion of `notify').

       Some options also have one or more single letter names.  There are two sets of single let-
       ter 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 com-
       mand 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  inver-
       sion  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  `#!'  mecha-
       nism 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 appro-
       priate.   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 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').

       CHASE_DOTS
              When  changing  to a directory containing a path segment `..' which would otherwise
              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 inter-
              active 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 direc-
              tory 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  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  comple-
              tion 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 comple-
              tion, 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 automatically added charac-
              ter  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 charac-
              ter 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 immediately cycle through the list in that case.

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

       COMPLETE_IN_WORD
              If unset, the cursor is set to the end of the word if completion is started. Other-
              wise 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 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 contains a pattern; simply turning on  the  GLOB_COM-
              PLETE 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.

       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 completion wid-
              gets 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 completion 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 message.  (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 expansion 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 presence 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 command 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  generation,
              etc.  (An initial unquoted `~' always produces named directory expansion.)

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

       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: glob-
              bing  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 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 sub-
              stitution 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 pattern
              matching instead of string matching.  This occurs wherever  history  modifiers  are
              valid, including glob qualifiers and parameters.  See the section Modifiers in zsh-
              expn(1).

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

       IGNORE_CLOSE_BRACES
              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 newline is necessary before the brace terminating a function
              or current shell construct.  When either option is set, a closing brace is  syntac-
              tically  significant  only  in command position.  Unlike IGNORE_BRACES, this option
              does not disable brace expansion.

              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 section `Filename Generation'.

       MAGIC_EQUAL_SUBST
              All  unquoted  arguments of the form `anything=expression' appearing after the com-
              mand name have filename expansion (that is, where expression has a leading  `~'  or
              `=') performed on expression 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 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 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 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 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.

       NUMERIC_GLOB_SORT
              If  numeric  filenames are matched by a filename generation pattern, sort the file-
              names 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-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 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 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.

       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 dura-
              tion (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  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.

       HIST_EXPIRE_DUPS_FIRST
              If  the  internal history needs to be trimmed to add the current command line, set-
              ting 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 avoid-
              ing history corruption when files are stored on NFS.

       HIST_FIND_NO_DUPS
              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.

       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 previous event).

       HIST_IGNORE_DUPS (-h)
              Do not enter command lines into the history list if they are duplicates of the pre-
              vious 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  van-
              ishes, allowing you to briefly reuse or edit the line.  If you want to make it van-
              ish 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 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  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 permis-
              sions 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-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 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  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
              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, .zpro-
              file, /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 executing 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.  Oth-
              erwise `>!' 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  (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  hang-
              ing 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 (normally Control-D) without printing the  nor-
              mal  warning  message.  This works only for normal widgets, not for completion wid-
              gets.

       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  invo-
              cations  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.

       HASH_EXECUTABLES_ONLY
              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 commands, 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 benefi-
              cial.

       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  com-
              mand  `/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 executa-
              bles 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 com-
              mand 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
              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 keyboards where the
              return key is too small, and the backquote key lies annoyingly 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 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 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 out-
              put 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.

              In  previous  versions of the shell, it was necessary to enable POSIX_JOBS in order
              for the builtin command wait to return the  status  of  background  jobs  that  had
              already exited.  This is no longer the case.

   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  newline)
              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 par-
              tial line is present (note that this is only successful if your terminal has  auto-
              matic 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 customize 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 per-
              formed 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 setting of C_BASES.

       C_PRECEDENCES
              This alters the precedence of arithmetic operators to be more like C and other pro-
              gramming 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 command.
              Setting this option mimics the behaviour of ksh 93; with the option unset  the  be-
              haviour 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 han-
              dled  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  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 parame-
              ter 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-
              tion.

       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  previ-
              ous  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  func-
              tion;  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  prob-
              lems 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 proceded 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 disables back-
              slashed escape sequences in echo strings unless the -e option is specified.

       CONTINUE_ON_ERROR
              If  a  fatal  error  is encountered (see the section ERRORS in zshmisc(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 con-
              structs 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.

       CSH_JUNKIE_HISTORY <C>
              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 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 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 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-compatible 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  parameter  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  refer-
              ence  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 exam-
              ple, 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 recom-
              mended 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 zsh-
              misc(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  pre-
              fixed  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  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 dur-
              ing  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 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 corre-
              sponding 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 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 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.

       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  `~{pfal-
              stad,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 - spe-
              cial 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'.)

       TRAPS_ASYNC
              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 initialisation if the stan-
              dard input is a tty and commands are being read from standard input.  (See the dis-
              cussion 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 run-
              ning.

       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  regard-
              less 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 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 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.  Specifically, 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 modifica-
              tions 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 spe-
              cial 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  charac-
              ters specially.

       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 guaranteed to reflect the current keymap.  This option is provided
              for compatibility; bindkey is the recommended interface.

       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 superfi-
              cial  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  dis-
              able 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 guaranteed 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  ter-
              minal.

OPTION ALIASES

       used just like normal option names when specifying options to the shell.
