setopt [ +-options ] [ name ... ] Set the options for the shell. All options speci- fied either with flags or by name are set. If no arguments are supplied, the names of all options currently set are printed. In option names, case is insignificant, and all underscore characters are ignored. If the -m flag is given the arguments are taken as patterns (should be quoted to preserve them from being interpreted as glob patterns) and all options with names matching these patterns are set. unsetopt [ +-options ] [ name ... ] Unset the options for the shell. All options spec- ified either with flags or by name are unset. If the -m flag is given the arguments are considered to be patterns (don't forget to quote them) and all options with names matching these patterns are unset. The following options may be set upon invocation of the shell, or with the set or setopt builtins. They are case insensitive and underscores are ignored, that is, "allex- port" is equivalent to "A__lleXP_ort". 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 direc- tory. 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 repeat- edly. This option is overridden by MENU_COMPLETE. 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 auto- matically. 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. BGNICE (-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. 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 speci- fier will always refer to the previous com- mand. CSH_JUNKIE_LOOPS Allow loop bodies to take the form "list; end" instead of "do list; done". CSH_JUNKIE_QUOTES Complain if a quoted expression runs off the end of a line; prevent quoted expressions from containing unescaped newlines. CSH_JUNKIE_TILDE Any unquoted = and ~ resulting from parame- ter substitution are eligible for file expansion. CSH_NULL_GLOB If a pattern for filename generation has no matches, delete the pattern from the argu- ment 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. EXTENDED_GLOB Treat the # and ^ characters as part of pat- terns for filename generation, etc. EXTENDED_HISTORY Save beginning and ending timestamps to the history file. The format of these times- tamps 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. 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_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 they begin with a blank. HIST_LIT (-j) Use literal (unparsed) versions of the his- tory 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 substitu- tion 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 comple- tions, show the type of each file with a trailing identifying mark. LOGIN (-l) This is a login shell. LONG_LIST_JOBS (-R) List jobs in the long format by default. 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 (glob- bing). MENU_COMPLETE (-Y) On an ambiguous completion, instead of list- ing 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 AUTO_MENU. MONITOR (-m) Allow job control. Set by default in inter- active 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 cre- ating 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, .zpro- file, /etc/zshrc, .zshrc, /etc/zlogin, .zlo- gin, 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 immedi- ately, rather than waiting until just before printing a prompt. NO_UNSET (-u) Treat unset parameters as an error when sub- stituting. NULL_GLOB (-G) If a pattern for filename generation has no matches, delete the pattern from the argu- ment list instead of reporting an error. Overrides NO_NOMATCH. NUMERIC_GLOB_SORT If numeric filenames are matched by a file- name 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. MAGIC_EQUAL_SUBST All unquoted arguments of the from identi- fier=expression have file expansion per- formed on expression as if it were a parame- ter assignment, although the argument is not otherwise treated specially. PRINT_EXIT_VALUE (-C) Print the exit value of programs with non- zero exit status. 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) See Parameter Expansion. 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 use- ful 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.
