A name may be any sequence of alphanumeric characters and _'s, or the single characters *, @, #, ?, -, $, or !. The value may be either a _s_c_a_l_a_r (a string), an integer, or an array. To assign a scalar or integer value to a parameter, use the ttttyyyyppppeeeesssseeeetttt builtin. To assign an array value, use sssseeeetttt ----AAAA _n_a_m_e _v_a_l_u_e .... The value of a parameter may also be assigned by writing: _n_a_m_e=_v_a_l_u_e ... If the integer attribute, -iiii, is set for _n_a_m_e, the _v_a_l_u_e is subject to arithmetic evaluation. The value of an array parameter may be assigned by writing: _n_a_m_e=(_v_a_l_u_e ...) ... Individual elements of an array may be selected using a subscript. A subscript of the form [[[[_e_x_p]]]] selects the single element _e_x_p, where _e_x_p is an arithmetic expression which will be subject to arithmetic expansion as if it were surrounded by "$((...))". The elements are numbered beginning with 1 unless the KKKKSSSSHHHH____AAAARRRRRRRRAAAAYYYYSSSS option is set when they are numbered from zero. A subscript of the form [[[[****]]]] or [[[[@@@@]]]] evaluates to all elements of an array; there is no difference between the two except when they appear within double quotes. "$foo[*]" evaluates to "$foo[1] $foo[2] ...", while "$foo[@]" evaluates to "$foo[1]" "$foo[2]", etc. A subscript of the form [[[[_e_x_p_1,,,,_e_x_p_2]]]] selects all elements in the range _e_x_p_1 to _e_x_p_2, inclusive. If one of the subscripts evaluates to a negative number, say -_n, then the _nth element from the end of the array is used. Thus "$foo[-3]" is the third element from the end of the array _f_o_o, and "$foo[1,- 1]" is the same as "$foo[*]". Subscripting may also be performed on non-array values, in which case the subscripts specify a substring to be extracted. For example, if FFFFOOOOOOOO is set to ffffoooooooobbbbaaaarrrr, then eeeecccchhhhoooo $$$$FFFFOOOOOOOO[[[[2222,,,,5555]]]] prints oooooooobbbbaaaa. Subscripts may be used inside braces used to delimit a parameter name, thus $$$${{{{ffffoooooooo[[[[2222]]]]}}}} is equivalent to $$$$ffffoooooooo[[[[2222]]]]. If the KKKKSSSSHHHH____AAAARRRRRRRRAAAAYYYYSSSS option is set, the braced form is the only one that will work, the subscript otherwise not being treated specially.

If the opening bracket or the comma is directly followed by an opening parentheses the string up to the matching closing one is considered to be a list of flags. The flags currently understood are: eeee this option has no effect and retained for backward compatibility only wwww if the parameter subscripted is a scalar than this flag makes subscription work on a per-word basis instead of characters ssss::::_s_t_r_i_n_g:::: this gives the _s_t_r_i_n_g that separates words (for use with the wwww flag) pppp Recognize the same escape sequences as the pppprrrriiiinnnntttt builtin in the string argument of a subsequent ssss flag. ffff if the parameter subscripted is a scalar than this flag makes subscription work on a per-line basis instead of characters. This is a shorthand for ppppwwwwssss::::\\\\nnnn::::. rrrr if this flag is given the _e_x_p is taken as a pattern and the result is the first matching array element, substring or word (if the parameter is an array, if it is a scalar, or if it is a scalar and the wwww flag is given, respectively); note that this is like giving a number: $$$$ffffoooooooo[[[[((((rrrr))))????????,,,,3333]]]] and $$$$ffffoooooooo[[[[((((rrrr))))????????,,,,((((rrrr))))ffff****]]]] work RRRR like rrrr, but gives the last match iiii like rrrr, but gives the index of the match instead; this may not be combined with a second argument IIII like iiii, but gives the index of the last match nnnn::::_e_x_p_r:::: if combined with rrrr, RRRR, , or IIII, makes them give the _n'th or _n'th last match (if _e_x_p_r evaluates to _n) PPPPoooossssiiiittttiiiioooonnnnaaaallll PPPPaaaarrrraaaammmmeeeetttteeeerrrrssss Positional parameters are set by the shell on invocation, by the sssseeeetttt builtin, or by direct assignment.

ZZZZSSSSHHHH____VVVVEEEERRRRSSSSIIIIOOOONNNN The version number of this zzzzsssshhhh. The following parameters are used by the shell: AAAARRRRGGGGVVVV0000 If exported, it's value is used as argv[0] of external commands. Usually used in constructs like 'ARGV0=emacs nethack'. BBBBAAAAUUUUDDDD The baud rate of the current connection. Used by the line editor update mechanism to compensate for a slow terminal by delaying updates until necessary. This may be profitably set to a lower value in some circumstances, e.g. for slow modems dialing into a communications server which is connected to a host via a fast link; in this case, this variable would be set by default to the speed of the fast link, and not the modem. This parameter should be set to the baud rate of the slowest part of the link for best performance. The compensation mechanism can be turned off by setting the variable to zero. ccccddddppppaaaatttthhhh ((((CCCCDDDDPPPPAAAATTTTHHHH)))) An array (colon-separated list) of directories specifying the search path for the ccccdddd command. CCCCOOOOLLLLUUUUMMMMNNNNSSSS The number of columns for this terminal session. Used for printing select lists and for the line editor.

FFFFCCCCEEEEDDDDIIIITTTT The default editor for the ffffcccc builtin. ffffiiiiggggnnnnoooorrrreeee ((((FFFFIIIIGGGGNNNNOOOORRRREEEE)))) An array (colon separated list) containing the suffixes of files to be ignored during filename completion. However, if the completion generates only files which would match if this variable would be ignored, than these files are completed anyway. ffffppppaaaatttthhhh ((((FFFFPPPPAAAATTTTHHHH)))) An array (colon separated list) of directories specifying the search path for function definitions. This path is searched when a function with the -uuuu attribute is referenced. If an executable file is found, then it is read and executed in the current environment. hhhhiiiissssttttcccchhhhaaaarrrrssss Three characters used by the shell's history and lexical analysis mechanism. The first character signals the start of a history substitution (default `!'). The second character signals the start of a quick history substitution (default `^'). The third character is the comment character (default `#'). HHHHIIIISSSSTTTTCCCCHHHHAAAARRRRSSSS Same as hhhhiiiissssttttcccchhhhaaaarrrrssss.... HHHHIIIISSSSTTTTFFFFIIIILLLLEEEE The file to save the history in when an interactive shell exits. If unset, the history is not saved. HHHHIIIISSSSTTTTSSSSIIIIZZZZEEEE The maximum size of the history list. HHHHOOOOMMMMEEEE The default argument for the ccccdddd command. IIIIFFFFSSSS Internal field separators, normally space, tab, and newline, that are used to separate words which result from command or parameter substitution and words read by the rrrreeeeaaaadddd builtin. Any characters from the set space, tab and newline that appear in the IFS are called _I_F_S _w_h_i_t_e _s_p_a_c_e. One or more IFS white space characters or one non-IFS white space character together with any adjacent IFS white space character delimit a field. If an IFS white space character appears twice consecutively in the IFS, this character is treated as if it were not an IFS white space character. KKKKEEEEYYYYTTTTIIIIMMMMEEEEOOOOUUUUTTTT The time the shell waits, in hundredths of seconds, for another key to be pressed when reading bound multi-character sequences.

LLLLCCCC____CCCCTTTTYYYYPPPPEEEE This variable determines the locale category for character handling functions. LLLLCCCC____MMMMEEEESSSSSSSSAAAAGGGGEEEESSSS This variable determines the language in which messages should be written. Note that zsh does not use message catalogs. LLLLCCCC____TTTTIIIIMMMMEEEE This variable determines the locale category for date and time formatting in promt escape sequences. LLLLIIIINNNNEEEESSSS The number of lines for this terminal session. Used for printing select lists and for the line editor. LLLLIIIISSSSTTTTMMMMAAAAXXXX In the line editor, the number of filenames to list without asking first. If set to zero, the shell asks only if the top of the listing would scroll off the screen. LLLLOOOOGGGGCCCCHHHHEEEECCCCKKKK The interval in seconds between checks for login/logout activity using the wwwwaaaattttcccchhhh parameter. MMMMAAAAIIIILLLL If this parameter is set and mmmmaaaaiiiillllppppaaaatttthhhh is not set, the shell looks for mail in the specified file. MMMMAAAAIIIILLLLCCCCHHHHEEEECCCCKKKK The interval in seconds between checks for new mail. mmmmaaaaiiiillllppppaaaatttthhhh ((((MMMMAAAAIIIILLLLPPPPAAAATTTTHHHH)))) An array (colon-separated list) of filenames to check for new mail. Each filename can be followed by a ? and a message that will be printed. The message will undergo parameter expansion, command substitution and arithmetic substitution with the variable $$$$____ defined as the name of the file that has changed. The default message is "_Y_o_u _h_a_v_e _n_e_w _m_a_i_l." If an element is a directory instead of a file the shell will recursively check every file in every subdirectory of the element. mmmmaaaannnnppppaaaatttthhhh ((((MMMMAAAANNNNPPPPAAAATTTTHHHH)))) An array (colon-separated list) whose value is not used by the shell. The mmmmaaaannnnppppaaaatttthhhh array can be useful, however, since setting it also sets Page 7 (printed 4/24/98) ZZZZSSSSHHHHPPPPAAAARRRRAAAAMMMM((((1111)))) zzzzsssshhhh vvvveeeerrrrssssiiiioooonnnn 3333....0000 ((((JJJJuuuunnnneeee 22226666,,,, 1111999999996666)))) ZZZZSSSSHHHHPPPPAAAARRRRAAAAMMMM((((1111)))) MMMMAAAANNNNPPPPAAAATTTTHHHH, and vice versa. NNNNUUUULLLLLLLLCCCCMMMMDDDD The command name to assume if a redirection is specified with no command. Defaults to ccccaaaatttt. For sh/ksh-like behavior, change this to ::::. For csh- like behavior, unset this parameter; the shell will print an error message if null commands are entered. ppppaaaatttthhhh ((((PPPPAAAATTTTHHHH)))) An array (colon-separated list) of directories to search for commands. When this parameter is set, each directory is scanned and all files found are put in a hash table. PPPPOOOOSSSSTTTTEEEEDDDDIIIITTTT This string is output whenever the line editor exits. It usually contains termcap strings to reset the terminal. PPPPSSSS1111 The primary prompt string, printed before a command is read; the default is "%m%# ". If the escape sequence takes an optional integer, it should appear between the '%' and the next character of the sequence. The following escape sequences are recognized: %%%%%%%% A `%'. %%%%)))) A `)'. %%%%dddd %%%%//// Present working directory ($PWD). %%%%~~~~ $PWD. If it has a named directory as its prefix, that part is replaced by a ~ followed by the name of the directory. If it starts with $HOME, that part is replaced by a ~. %%%%cccc %%%%.... %%%%CCCC Trailing component of $PWD. An integer may follow the '%' to get more than one component. Unless %%%%CCCC is used, tilde expansion is performed first. %%%%hhhh %%%%!!!! Current history event number %%%%MMMM The full machine hostname. %%%%mmmm The hostname up to the first '.'.

The return code of the last command executed just before the prompt. %%%%____ The status of the parser, i.e. the shell constructs (like `if' and `for') that have been started on the command line. If given an integer number that many strings will be printed; zero or no integer means print as many as there are. %%%%EEEE Clears to end of line. %%%%#### A '#' if the shell is running as root, a '%' if not. Equivalent to %(#.#.%%). %%%%vvvv The value of the first element of the $psvar array parameter.

The string within the braces should not change the cursor position. %%%%((((xxxx._t_r_u_e-_t_e_x_t._f_a_l_s_e-_t_e_x_t)))) Specifies a ternary expression. The character following the xxxx is arbitrary; the same character is used to separate the text for the "true" result from that for the "false" result. This separator may not appear in the _t_r_u_e-_t_e_x_t, except as part of a % sequence. A `)' may appear in the _f_a_l_s_e- _t_e_x_t as `%)'. _T_r_u_e-_t_e_x_t and _f_a_l_s_e-_t_e_x_t may both contain arbitrarily-nested escape sequences, including further ternary expressions. The left parenthesis may be preceded or followed by a positive integer _n, which defaults to zero. The test character xxxx may be any of the following: cccc .... ~~~~ True if the current path, with prefix replacement, has at least _n elements. //// Page 9 (printed 4/24/98) ZZZZSSSSHHHHPPPPAAAARRRRAAAAMMMM((((1111)))) zzzzsssshhhh vvvveeeerrrrssssiiiioooonnnn 3333....0000 ((((JJJJuuuunnnneeee 22226666,,,, 1111999999996666)))) ZZZZSSSSHHHHPPPPAAAARRRRAAAAMMMM((((1111)))) CCCC True if the current absolute path has at least _n elements. tttt True if the time in minutes is equal to _n.

DDDD True if the month is equal to _n (January = 0). wwww True if the day of the week is equal to _n (Sunday = 0). ???? True if the exit status of the last command was _n. #### True if the effective uid of the current process is _n. gggg True if the effective gid of the current process is _n. LLLL True if the SHLVL parameter is at least _n.

The third form is equivalent to `%_x_s_t_r_i_n_g_x', i.e. _x may be `<' or `>'. The numeric argument, which in the third form may appear immediately after the `[', specifies the maximum permitted length of the various strings that can be displayed in the prompt. If this integer is zero, or missing, truncation is disabled. Truncation is initially disabled. The forms with `<' truncate at the left of the string, and the forms with `>' truncate at the right of the string. For example, if the current directory is `/home/pike', the prompt `%8<..<%/' will expand to `..e/pike'. The _s_t_r_i_n_g will be displayed in place of the truncated portion of any string. In this string, the terminating character (`<', `>' or `]'), or in fact any character, may be quoted by a preceding `\'. % sequences are _n_o_t treated specially. If the _s_t_r_i_n_g is longer than the specified truncation length, it will appear in full, completely replacing the truncated string.

These parameters do not have any special meaning in sh/ksh compatibility mode. ppppssssvvvvaaaarrrr ((((PPPPSSSSVVVVAAAARRRR)))) An array (colon-separated list) whose first nine values can be used in PPPPRRRROOOOMMMMPPPPTTTT strings. Setting ppppssssvvvvaaaarrrr also sets PPPPSSSSVVVVAAAARRRR, and vice versa. pppprrrroooommmmpppptttt Same as PPPPSSSS1111. It has no special meaning in sh/ksh compatibility mode.

The modes apply only to the command, and are reset when it finishes or is suspended. If the command is suspended and continued later with the ffffgggg or wwwwaaaaiiiitttt builtins it will see the modes specified by STTY, as if it were not suspended. This (intentionally) does not apply if the command is continued via "kill -CONT". STTY is ignored if the command is run in the background, or if it is in the environment of the shell but not explicitly assigned to in the input line. This avoids running stty at every external command by accidentally exporting it. Also note that STTY should not be used for window size specifications; these will not be local to the command. TTTTIIIIMMMMEEEEFFFFMMMMTTTT The format of process time reports with the ttttiiiimmmmeeee keyword. The default is "%E real %U user %S system %P %J". Recognizes the following escape sequences: %%%%%%%% A `%'. %%%%UUUU CPU seconds spent in user mode. %%%%SSSS CPU seconds spent in kernel mode. %%%%EEEE Elapsed time in seconds. %%%%PPPP The CPU percentage, computed as (%U+%S)/%E. %%%%JJJJ The name of this job. A star may be inserted between the percent sign and flags printing time. This cause the time to be printed in hh:mm:ss.ttt format (hours and minutes are only printed if they are not zero). TTTTMMMMOOOOUUUUTTTT If this parameter is nonzero, the shell will receive an AAAALLLLRRRRMMMM signal if a command is not entered within the specified number of seconds after issuing a prompt. If there is a trap on SSSSIIIIGGGGAAAALLLLRRRRMMMM, it will be executed and a new alarm is scheduled using the value of the TTTTMMMMOOOOUUUUTTTT parametr after exececuting the trap. If no trap is set, and the idle time of the terminal is not less than the value of the TTTTMMMMOOOOUUUUTTTT parameter, zsh terminates. Otherwise a new alarm is scheduled to TTTTMMMMOOOOUUUUTTTT seconds after the last keypress. TTTTMMMMPPPPPPPPRRRREEEEFFFFIIIIXXXX A pathname prefix which the shell will use for all temporary files. Note that this should include an initial part for the file name as well as any directory names. The default is /tmp/zsh. wwwwaaaattttcccchhhh ((((WWWWAAAATTTTCCCCHHHH)))) An array (colon-separated list) of login/logout events to report. If it contains the single word "all", then all login/logout events are reported.

An entry in this list may consist of a username, an `@' followed by a remote hostname, and a `%' followed by a line (tty). Any or all of these components may be present in an entry; if a login/logout event matches all of them, it is reported. WWWWAAAATTTTCCCCHHHHFFFFMMMMTTTT The format of login/logout reports if the wwwwaaaattttcccchhhh parameter is set. Default is "%n has %a %l from %m." Recognizes the following escape sequences: %%%%nnnn The name of the user that logged in/out. %%%%aaaa The observed action, i.e. "logged on" or "logged off". %%%%llll The line (tty) the user is logged in on. %%%%MMMM The full hostname of the remote host. %%%%mmmm The hostname up to the first ".". If only the ip address is available or the utmp field contains the name of an X-windows display, the whole name is printed. NNNNOOOOTTTTEEEE:::: The %m and %M escapes will work only if there is a host name field in the utmp on your machine. Otherwise they are treated as ordinary strings. %%%%SSSS ((((%%%%ssss)))) Start (stop) standout mode. %%%%UUUU ((((%%%%uuuu)))) Start (stop) underline mode. %%%%BBBB ((((%%%%bbbb)))) Start (stop) boldface mode. %%%%tttt %%%%@@@@ The time, in 12-hour, am/pm format. %%%%TTTT The time, in 24-hour format. %%%%wwww The date in day-dd format. %%%%WWWW The date in mm/dd/yy format. %%%%DDDD The date in yy-mm-dd format. %%%%((((xxxx:_t_r_u_e-_t_e_x_t:_f_a_l_s_e-_t_e_x_t)))) Specifies a ternary expression. The character following the xxxx is arbitrary; the same character is used to separate the text for the "true" result from that for the "false" result. Both the separator and the right parenthesis may be escaped with a backslash. Ternary expressions may be nested. The test character xxxx may be any one of llll, nnnn, mmmm, or MMMM, which indicate a "true" result if the corresponding escape sequence would Page 13 (printed 4/24/98) ZZZZSSSSHHHHPPPPAAAARRRRAAAAMMMM((((1111)))) zzzzsssshhhh vvvveeeerrrrssssiiiioooonnnn 3333....0000 ((((JJJJuuuunnnneeee 22226666,,,, 1111999999996666)))) ZZZZSSSSHHHHPPPPAAAARRRRAAAAMMMM((((1111)))) return a non-empty value; or may be aaaa, which indicates a "true" result if the watched user has logged in, or "false" if he has logged out. Other characters evaluate to neither true nor false; the entire expression is omitted in this case. If the result is "true", then the _t_r_u_e-_t_e_x_t is formatted according to the rules above and printed, and the _f_a_l_s_e-_t_e_x_t is skipped. If "false", the _t_r_u_e-_t_e_x_t is skipped and the _f_a_l_s_e-_t_e_x_t is formatted and printed. Either or both of the branches may be empty, but both separators must be present in any case. WWWWOOOORRRRDDDDCCCCHHHHAAAARRRRSSSS A list of nonalphanumeric characters considered part of a word by the line editor.
