NAME

DESCRIPTIONS

ALL_EXPORT (-a)

All parameters subsequently defined are automatically exported.

ALWAYS_LAST_PROMPT

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 with the cursor in the word was started and it results in only one match, the cursor is placed at the end of the word.

APPEND_HISTORY

If this is set, zsh sessions will append their history list to the history file, rather than overwrite it. Thus, multiple parallel zsh sessions will all have their history lists added to the history file, in the order they are killed.

AUTO_CD (-J)

If a command is not in the hash table, and there exists an executable directory by that name, perform the cd command to that directory.

AUTO_LIST (-9)

Automatically list choices on an ambiguous completion.

AUTO_MENU

Automatically use menu completion after the second consecutive request for completion, for example by pressing the TAB key repeatedly. This option is overridden by MENU_COMPLETE.

AUTO_NAME_DIRS

Any parameter that is set to the absolute name of a directory immediately becomes a name for that directory in the usual form ~param. If this option is not set, the parameter must be used in that form for it to become a name (a command-line completion is sufficient for this).

AUTO_PARAM_KEYS

If a parameter name was completed and the next character typed is one of those that have to come directly after the name (like `}', `:', etc.) they are placed there automatically.

AUTO_PARAM_SLASH

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

AUTO_PUSHD (-N)

Make cd act like pushd.

AUTO_REMOVE_SLASH

When the last character resulting from a completion is a slash and the next character typed is a word delimiter, remove the slash.

AUTO_RESUME (-W)

Treat single word simple commands without redirection as candidates for resumption of an existing job.

BG_NICE (-6)

Run all background jobs at a lower priority. This option is set by default.

BRACE_CCL

Allow brace expansions of the form {a-zA-Z}, etc.

BSD_ECHO

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.

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 Filename Expansion above).

CHASE_LINKS (-w)

Resolve symbolic links to their true values.

COMPLETE_ALIASES

If set, aliases on the command line are not internally substituted before completion is attempted.

COMPLETE_IN_WORD

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

CORRECT (-0)

Try to correct the spelling of commands.

CORRECT_ALL (-O)

Try to correct the spelling of all arguments in a line.

CSH_JUNKIE_HISTORY

A history reference without an event specifier will always refer to the previous command.

CSH_JUNKIE_LOOPS

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

CSH_JUNKIE_PAREN

Allow for, if and while loops where the argument list is given in parentheses. Otherwise, the parentheses will be treated as specifying a subshell.

CSH_JUNKIE_QUOTES

Complain if a quoted expression runs off the end of a line; prevent quoted expressions from containing unescaped newlines.

CSH_NULL_GLOB

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 NULLGLOB.

ERR_EXIT (-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.

EXTENDED_GLOB

Treat the #, ~ and ^ characters as part of patterns for filename generation, etc. (An initial unquoted ~ always produces named directory expansion as in Filename Expansion above.)

EXTENDED_HISTORY

Save beginning and ending timestamps to the history file. The format of these timestamps is :<beginning time>:<ending time>:<command>.

GLOB_COMPLETE

When the current word has a glob pattern, do not insert all the words resulting from the expansion but cycle through them like MENU_COMPLETE. If no matches are found, a `*' is added to the end of the word or inserted at the cursor if COMPLETE_IN_WORD is set, and expansion is attempted again. Using patterns works not only for files but for all completions, such as options, user names, etc.

GLOB_DOTS (-4)

Do not require a leading . in a filename to be matched explicitly.

GLOB_SUBST

Treat any characters resulting from parameter substitution as being eligible for file expansion and filename generation, and any characters resulting from command substitution as being eligible for filename generation.

HASH_CMDS

Place the location of each command in the hash table the first time it is executed. If this option is unset, no path hashing will be done at all.

HASH_DIRS

Whenever a command is executed, hash the directory containing it, as well as all directories that occur earlier in the path. Has no effect if HASH_CMDS is unset.

HASH_LIST_ALL

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

HIST_ALLOW_CLOBBER

Add `|' to output redirections in the history. This allows history references to clobber files even when NO_CLOBBER is set.

HIST_IGNORE_DUPS (-h)

Do not enter command lines into the history list if they are duplicates of the previous event.

HIST_IGNORE_SPACE (-g)

Do not enter command lines into the history list if any command on the line begins with a blank.

HIST_LIT (-j)

Use literal (unparsed) versions of the history lines in the editor.

HIST_NO_STORE

Remove the history (fc -l) command from the history when invoked.

HIST_VERIFY

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

IGNORE_BRACES (-I)

Do not perform brace expansion.

IGNORE_EOF (-7)

Do not exit on end-of-file. Require the use of exit or logout instead.

INTERACTIVE (-i)

This is an interactive shell.

INTERACTIVE_COMMENTS (-k)

Allow comments even in interactive shells.

KSH_OPTION_PRINT

Alters the way options settings are printed.

LIST_AMBIGUOUS

If this option is set, completions are shown only if the completions don't have a unambiguous prefix or suffix that could be inserted in the command line.

LIST_TYPES (-X)

When listing files that are possible completions, show the type of each file with a trailing identifying mark.

LOCAL_OPTIONS

If this option is set at the point of return from a shell function, all the options (including this one) which were in force upon entry to the function are restored. 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.

LOGIN (-l)

This is a login shell.

LONG_LIST_JOBS (-R)

List jobs in the long format by default.

MAGIC_EQUAL_SUBST

All unquoted arguments of the from identifier=expression have file expansion performed on expression as if it were a parameter assignment, although the argument is not otherwise treated specially.

MAIL_WARNING (-U)

Print a warning message if a mail file has been accessed since the shell last checked.

MARK_DIRS (-8)

Append a trailing / to all directory names resulting from filename generation (globbing).

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.

MONITOR (-m)

Allow job control. Set by default in interactive shells.

NO_BAD_PATTERN (-2)

If a pattern for filename generation is badly formed, leave it unchanged in the argument list instead of printing an error.

NO_BANG_HIST (-K)

Do not perform textual history substitution. Do not treat the ! character specially.

NO_BEEP (-B)

Do not beep.

NO_CLOBBER (-1)

Prevents > redirection from truncating existing files. >! may be used to truncate a file instead. Also prevents >> from creating files. >>! may be used instead.

NO_EQUALS

Don't perform = filename substitution.

NO_EXEC (-n)

Read commands and check them for syntax errors, but do not execute them.

NO_GLOB (-F)

Disable filename generation.

NO_FLOW_CONTROL

Disable output flow control via start/stop characters (usually assigned to ^S/^Q) in the shell's editor.

NO_HIST_BEEP

Don't beep when an attempt is made to access a history entry which isn't there.

NO_HUP

Don't send the HUP signal to running jobs when the shell exits.

NO_LIST_BEEP

Don't beep on an ambiguous completion.

NO_NOMATCH (-3)

If a pattern for filename generation has no matches, leave it unchanged in the argument list instead of printing an error. This also applies to file expansion of an initial ~ or =.

NO_PROMPT_CR (-V)

Don't print a carriage return just before printing a prompt in the line editor.

NO_RCS (-f)

Source only the /etc/zshenv file. Do not source the .zshenv, /etc/zprofile, .zprofile, /etc/zshrc, .zshrc, /etc/zlogin, .zlogin, or .zlogout files.

NO_SHORT_LOOPS

Disallow the short forms of for, select, if, and function constructs.

NOTIFY (-5)

Report the status of background jobs immediately, rather than waiting until just before printing a prompt.

NO_UNSET (-u)

Treat unset parameters as an error when substituting.

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 NO_NOMATCH.

NUMERIC_GLOB_SORT

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

OVER_STRIKE

Start up the line editor in overstrike mode.

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 types "X11/xinit", the command "/usr/local/bin/X11/xinit" will be executed (assuming it exists). This applies to the . builtin as well as to command execution. Commands explicitly beginning with "./" or "../" are not subject to path search.

PRINT_EXIT_VALUE (-C)

Print the exit value of programs with non-zero exit status.

PRIVILEGED (-p)

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

PROMPT_SUBST

If set expressions like ${...}, $(...), $[...] and $((...)) in prompts will be expanded.

PUSHD_IGNORE_DUPS

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

PUSHD_MINUS

See popd below.

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.

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.

RC_QUOTES

Allow the character sequence '' to signify a single quote within singly quoted strings.

REC_EXACT (-S)

In completion, recognize exact matches even if they are ambiguous.

RM_STAR_SILENT (-H)

Do not query the user before executing "rm *" or "rm path/*".

SHIN_STDIN (-s)

Read commands from the standard input.

SH_WORD_SPLIT (-y)

See Parameter Expansion.

SINGLE_LINE_ZLE (-M)

Use single-line command line editing instead of multi-line.

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.

VERBOSE (-v)

Print shell input lines as they are read.

XTRACE (-x)

Print commands and their arguments as they are executed.

ZLE (-Z)

Use the zsh line editor.
