Options

The following options may be set upon invocation of the shell, or with the set or setopt builtins. The names are case-insensitive and underscores are ignored, that is, `allexport' is equivalent to `A_lleXP_ort'.

þ þ

ALL_EXPORT (-a)
All parameters subsequently defined are automatically exported. þ þ

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.þ

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. þ

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. See section Shell Builtin Commands, for the fc command.þ þ

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. þ þ

AUTO_LIST (-9)
Automatically list choices on an ambiguous completion. þ þ

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

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).þ

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.þ þ þ

AUTO_PUSHD (-N)
Make cd act like pushd. þ þ

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.þ þ þ

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

BGNICE (-6)
Run all background jobs at a lower priority. This option is set by default. þ þ þ

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

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 section Filename Expansion).þ þ þ

CHASE_LINKS (-w)
Resolve symbolic links to their true values. þ þ

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

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

CORRECT (-0)
Try to correct the spelling of commands. þ

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

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

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

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.þ þ þ

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

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.þ þ þ þ

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 NULL_GLOB.þ þ

ERR_EXIT (-e)
If a command has a non-zero exit status, execute the ZERR trap, if set, and exit.þ þ

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

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

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 completion is attempted again. Using patterns works not only for files but for all completions, such as options, user names, etc.þ þ

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

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.þ þ þ

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.þ

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

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

HIST_IGNORE_SPACE (-g)
Do not enter command lines into the history list if they begin with a blank. þ þ

HIST_LIT (-j)
Use literal (unparsed) versions of the history lines in the editor. þ

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

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. þ þ þ þ

IGNORE_BRACES (-I)
Do not perform brace expansion. þ þ

IGNORE_EOF (-7)
Do not exit on end-of-file. Require the use of exit or logout instead.þ

INTERACTIVE (-i)
This is an interactive shell. þ þ

INTERACTIVE_COMMENTS (-k)
Allow comments even in interactive shells. þ þ þ

KSH_OPTION_PRINT
Alters the way options settings are printed. þ þ þ

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

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

LOGIN (-l)
This is a login shell. þ þ þ

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

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

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

MARK_DIRS (-8)
Append a trailing / to all directory names resulting from filename generation (globbing).þ þ

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.þ þ

MONITOR (-m)
Allow job control. Set by default in interactive shells. þ þ

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. þ þ þ

NO_BANG_HIST (-K)
Do not perform textual history substitution. Do not treat the ! character specially.þ þ þ

NO_BEEP (-B)
Do not beep. þ þ þ

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.þ þ

NO_EQUALS
Don't perform = filename substitution. þ þ

NO_EXEC (-n)
Read commands and check them for syntax errors, but do not execute them. þ þ

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

NO_GLOB (-F)
Disable filename generation. þ þ þ

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

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

NO_LIST_BEEP
Don't beep on an ambiguous completion. þ þ

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 =.þ þ

NO_PROMPT_CR (-V)
Don't print a carriage return just before printing a prompt in the line editor. þ þ

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.þ

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

NOTIFY (-5)
Report the status of background jobs immediately, rather than waiting until just before printing a prompt. þ þ þ

NO_UNSET (-u)
Treat unset parameters as an error when substituting. þ þ

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.þ þ

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

OVERSTRIKE
Start up the line editor in overstrike mode. þ þ

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.þ þ

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

PROMPT_SUBST
Expressions like ${...}, $(...), and $[...] in prompts will be expanded.þ þ

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

PUSHD_MINUS
See section Shell Builtin Commands, for the popd command. þ þ

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

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

RC_EXPAND_PARAM (-P)
See section Parameter Expansion. þ þ þ

RC_QUOTES
Allow the character sequence " to signify a single quote within singly quoted strings.þ þ

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

RM_STAR_SILENT (-H)
Do not query the user before executing rm * or rm path/*. þ

SHIN_STDIN (-s)
Read commands from the standard input. þ þ þ

SH_WORD_SPLIT (-y)
See section Parameter Expansion. þ þ

SINGLE_LINE_ZLE (-M)
Use single-line command line editing instead of multi-line. þ þ þ

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. þ þ

VERBOSE (-v)
Print shell input lines as they are read. þ þ

XTRACE (-x)
Print commands and their arguments as they are executed. þ þ þ

ZLE (-Z)
Use the zsh line editor.
