ZSHPARAM(1)									      ZSHPARAM(1)

NAME
       zshparam - zsh parameters

DESCRIPTION
       A  parameter  has a name, a value, and a number of attributes.  A name may be any sequence
       of alphanumeric characters and underscores, or the single characters `*', `@',  `#',  `?',
       `-',  `$',  or  `!'.   The value may be a scalar (a string), an integer, an array (indexed
       numerically), or an associative array (an unordered set of name-value  pairs,  indexed  by
       name).	To  declare  the type of a parameter, or to assign a scalar or integer value to a
       parameter, use the typeset builtin.

       The value of a scalar or integer parameter may also be assigned by writing:

	      name=value

       If the integer attribute, -i, is set for name, the value is subject to arithmetic  evalua-
       tion.   Furthermore,  by replacing `=' with `+=', a parameter can be added or appended to.
       See the section `Array Parameters' for additional forms of assignment.

       To refer to the value of a parameter, write `$name' or `${name}'.  See Parameter Expansion
       in zshexpn(1) for complete details.

       In  the	parameter  lists that follow, the mark `<S>' indicates that the parameter is spe-
       cial.  Special parameters cannot have their  type  changed  or  their  readonly	attribute
       turned off, and if a special parameter is unset, then later recreated, the special proper-
       ties will be retained.  `<Z>' indicates that the parameter does not exist when  the  shell
       initializes in sh or ksh emulation mode.

ARRAY PARAMETERS
       To assign an array value, write one of:

	      set -A name value ...
	      name=(value ...)

       If  no  parameter  name	exists, an ordinary array parameter is created.  If the parameter
       name exists and is a scalar, it is replaced by a new array.  Ordinary array parameters may
       also be explicitly declared with:

	      typeset -a name

       Associative arrays must be declared before assignment, by using:

	      typeset -A name

       When  name  refers  to  an  associative array, the list in an assignment is interpreted as
       alternating keys and values:

	      set -A name key value ...
	      name=(key value ...)

       Every key must have a value in this case.  Note that this assigns  to  the  entire  array,
       deleting any elements that do not appear in the list.

       To create an empty array (including associative arrays), use one of:

	      set -A name
	      name=()

   Array Subscripts
       Individual  elements  of  an  array may be selected using a subscript.  A subscript of the
       form `[exp]' selects the single element exp, where exp is an arithmetic	expression  which
       will  be subject to arithmetic expansion as if it were surrounded by `$((...))'.  The ele-
       ments are numbered beginning with 1, unless the KSH_ARRAYS option is  set  in  which  case
       they are numbered from zero.

       Subscripts may be used inside braces used to delimit a parameter name, thus `${foo[2]}' is
       equivalent to `$foo[2]'.  If the KSH_ARRAYS option is set, the braced form is the only one
       that works, as bracketed expressions otherwise are not treated as subscripts.

       If  the	KSH_ARRAYS option is not set, then by default accesses to an array element with a
       subscript that evaluates to zero return an empty string, while an attempt to write such an
       element	is treated as an error.  For backward compatibility the KSH_ZERO_SUBSCRIPT option
       can be set to cause subscript values 0 and 1 to be equivalent; see the description of  the
       option in zshoptions(1).

       The  same  subscripting	syntax	is used for associative arrays, except that no arithmetic
       expansion is applied to exp.  However, the parsing rules for arithmetic expressions  still
       apply, which affects the way that certain special characters must be protected from inter-
       pretation.  See Subscript Parsing below for details.

       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]  $foo[2]  ..."',  whereas  `"$foo[@]"'	evaluates  to  `"$foo[1]"
       "$foo[2]"  ...'.  For associative arrays, `[*]' or `[@]' evaluate to all the values, in no
       particular order.  Note that this does not substitute the keys; see the documentation  for
       the  `k' flag under Parameter Expansion Flags in zshexpn(1) for complete details.  When an
       array parameter is referenced as `$name' (with no subscript) it evaluates  to  `$name[*]',
       unless  the  KSH_ARRAYS	option	is set in which case it evaluates to `${name[0]}' (for an
       associative array, this means the value of the key `0', which may not exist even if  there
       are values for other keys).

       A  subscript  of  the  form  `[exp1,exp2]' selects all elements in the range exp1 to exp2,
       inclusive. (Associative arrays are unordered, and so do not support ranges.) 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 `$foo[-3]' is the third element from the end of  the  array  foo,
       and `$foo[1,-1]' is the same as `$foo[*]'.

       Subscripting may also be performed on non-array values, in which case the subscripts spec-
       ify a substring to be extracted.  For example, if FOO  is  set  to  `foobar',  then  `echo
       $FOO[2,5]' prints `ooba'.

   Array Element Assignment
       A subscript may be used on the left side of an assignment like so:

	      name[exp]=value

       In  this  form  of  assignment  the  element  or range specified by exp is replaced by the
       expression on the right side.  An array (but not an associative array) may be  created  by
       assignment  to  a range or element.  Arrays do not nest, so assigning a parenthesized list
       of values to an element or range changes the number of elements in the array, shifting the
       other  elements	to  accommodate  the  new values.  (This is not supported for associative
       arrays.)

       This syntax also works as an argument to the typeset command:

	      typeset "name[exp]"=value

       The value may not be a parenthesized list in this case;	only  single-element  assignments
       may  be	made  with  typeset.   Note that quotes are necessary in this case to prevent the
       brackets from being interpreted as filename generation operators.  The  noglob  precommand
       modifier could be used instead.

       To delete an element of an ordinary array, assign `()' to that element.	To delete an ele-
       ment of an associative array, use the unset command:

	      unset "name[exp]"

   Subscript Flags
       If the opening bracket, or the comma in a range, in any subscript expression  is  directly
       followed  by  an opening parenthesis, the string up to the matching closing one is consid-
       ered to be a list of flags, as in `name[(flags)exp]'.

       The flags s, n and b take an argument; the delimiter is shown below as `:', but any  char-
       acter,  or the matching pairs `(...)', `{...}', `[...]', or `<...>', may be used, but note
       that `<...>' can only be used if the subscript is inside a double quoted expression  or	a
       parameter  substitution enclosed in braces as otherwise the expression is interpreted as a
       redirection.

       The flags currently understood are:

       w      If the parameter subscripted is a scalar then this flag makes subscripting work  on
	      words  instead of characters.  The default word separator is whitespace.	This flag
	      may not be used with the i or I flag.

       s:string:
	      This gives the string that separates words (for use with the w flag).   The  delim-
	      iter character : is arbitrary; see above.

       p      Recognize  the same escape sequences as the print builtin in the string argument of
	      a subsequent `s' flag.

       f      If the parameter subscripted is a scalar then this flag makes subscripting work  on
	      lines  instead  of characters, i.e. with elements separated by newlines.	This is a
	      shorthand for `pws:\n:'.

       r      Reverse subscripting: if this flag is given, the exp 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  `w'  flag  is  given,
	      respectively).   The  subscript used is the number of the matching element, so that
	      pairs of subscripts such as `$foo[(r)??,3]' and `$foo[(r)??,(r)f*]' are possible if
	      the  parameter  is  not  an  associative array.  If the parameter is an associative
	      array, only the value part of each pair is compared to the pattern, and the  result
	      is that value.

	      If  a search through an ordinary array failed, the search sets the subscript to one
	      past the end of the array, and hence ${array[(r)pattern]} will substitute the empty
	      string.	Thus  the  success  of	a search can be tested by using the (i) flag, for
	      example (assuming the option KSH_ARRAYS is not in effect):

		     [[ ${array[(i)pattern]} -le ${#array} ]]

	      If KSH_ARRAYS is in effect, the -le should be replaced by -lt.

       R      Like `r', but gives the last match.  For associative  arrays,  gives  all  possible
	      matches.	May be used for assigning to ordinary array elements, but not for assign-
	      ing to associative arrays.  On failure, for normal arrays this has  the  effect  of
	      returning the element corresponding to subscript 0; this is empty unless one of the
	      options KSH_ARRAYS or KSH_ZERO_SUBSCRIPT is in effect.

	      Note that in subscripts with both `r' and `R' pattern characters are active even if
	      they  were  substituted  for  a  parameter (regardless of the setting of GLOB_SUBST
	      which controls this feature in normal pattern matching).	The flag `e' can be added
	      to  inhibit pattern matching.  As this flag does not inhibit other forms of substi-
	      tution, care is still required; using a parameter to hold the key has  the  desired
	      effect:

		     key2='original key'
		     print ${array[(Re)$key2]}

       i      Like `r', but gives the index of the match instead; this may not be combined with a
	      second argument.	On the left side of an assignment, behaves like `r'.   For  asso-
	      ciative arrays, the key part of each pair is compared to the pattern, and the first
	      matching key found is the result.  On failure substitutes the length of  the  array
	      plus  one,  as  discussed  under the description of `r', or the empty string for an
	      associative array.

       I      Like `i', but gives the index of the last match, or all possible matching  keys  in
	      an  associative  array.  On failure substitutes 0, or the empty string for an asso-
	      ciative array.  This flag is best when testing for  values  or  keys  that  do  not
	      exist.

       k      If  used	in  a  subscript on an associative array, this flag causes the keys to be
	      interpreted as patterns, and returns the value for the first key found where exp is
	      matched  by the key.  Note this could be any such key as no ordering of associative
	      arrays is defined.  This flag does not work on the left side of an assignment to an
	      associative array element.  If used on another type of parameter, this behaves like
	      `r'.

       K      On an associative array this is like `k'	but  returns  all  values  where  exp  is
	      matched by the keys.  On other types of parameters this has the same effect as `R'.

       n:expr:
	      If  combined  with  `r', `R', `i' or `I', makes them give the nth or nth last match
	      (if expr evaluates to n).  This flag is ignored when the array is associative.  The
	      delimiter character : is arbitrary; see above.

       b:expr:
	      If combined with `r', `R', `i' or `I', makes them begin at the nth or nth last ele-
	      ment, word, or character (if expr evaluates to n).  This flag is ignored	when  the
	      array is associative.  The delimiter character : is arbitrary; see above.

       e      This  flag  causes any pattern matching that would be performed on the subscript to
	      use plain string matching instead.  Hence `${array[(re)*]}' matches only the  array
	      element  whose value is *.  Note that other forms of substitution such as parameter
	      substitution are not inhibited.

	      This flag can also be used to force * or @ to be interpreted as a single key rather
	      than  as	a reference to all values.  It may be used for either purpose on the left
	      side of an assignment.

       See Parameter Expansion Flags (zshexpn(1)) for additional ways to manipulate  the  results
       of array subscripting.

   Subscript Parsing
       This  discussion  applies mainly to associative array key strings and to patterns used for
       reverse subscripting (the `r', `R', `i', etc. flags), but it  may  also	affect	parameter
       substitutions that appear as part of an arithmetic expression in an ordinary subscript.

       It is possible to avoid the use of subscripts in assignments to associative array elements
       by using the syntax:

		 aa+=('key with "*strange*" characters' 'value string')

       This adds a new key/value pair if the key is not already present, and replaces  the  value
       for the existing key if it is.

       The  basic  rule  to remember when writing a subscript expression is that all text between
       the opening `[' and the closing `]' is interpreted as if it were  in  double  quotes  (see
       zshmisc(1)).   However, unlike double quotes which normally cannot nest, subscript expres-
       sions may appear inside double-quoted strings or inside other  subscript  expressions  (or
       both!), so the rules have two important differences.

       The  first  difference  is  that brackets (`[' and `]') must appear as balanced pairs in a
       subscript expression unless they are preceded by a backslash (`\').  Therefore,	within	a
       subscript  expression  (and unlike true double-quoting) the sequence `\[' becomes `[', and
       similarly `\]' becomes `]'.  This applies even in cases where a backslash is not  normally
       required;  for  example,  the  pattern  `[^[]'  (to match any character other than an open
       bracket) should be written `[^\[]' in a reverse-subscript  pattern.   However,  note  that
       `\[^\[\]'  and  even  `\[^[]' mean the same thing, because backslashes are always stripped
       when they appear before brackets!

       The same rule applies to parentheses (`(' and `)') and braces (`{'  and	`}'):  they  must
       appear  either  in balanced pairs or preceded by a backslash, and backslashes that protect
       parentheses or braces are removed during parsing.  This is  because  parameter  expansions
       may  be	surrounded  by	balanced  braces,  and subscript flags are introduced by balanced
       parentheses.

       The second difference is that a double-quote (`"') may  appear  as  part  of  a	subscript
       expression  without  being  preceded by a backslash, and therefore that the two characters
       `\"' remain as two characters in the subscript (in true double-quoting, `\"' becomes `"').
       However,  because  of the standard shell quoting rules, any double-quotes that appear must
       occur in balanced pairs unless preceded by a backslash.	This makes it more  difficult  to
       write  a  subscript expression that contains an odd number of double-quote characters, but
       the reason for this difference is so that when a subscript expression appears inside  true
       double-quotes, one can still write `\"' (rather than `\\\"') for `"'.

       To  use	an odd number of double quotes as a key in an assignment, use the typeset builtin
       and an enclosing pair of double quotes; to refer to the value of that key, again use  dou-
       ble quotes:

	      typeset -A aa
	      typeset "aa[one\"two\"three\"quotes]"=QQQ
	      print "$aa[one\"two\"three\"quotes]"

       It  is  important  to note that the quoting rules do not change when a parameter expansion
       with a subscript is nested inside another subscript expression.	That is, it is not neces-
       sary to use additional backslashes within the inner subscript expression; they are removed
       only once, from the innermost subscript outwards.  Parameters are also expanded	from  the
       innermost  subscript  first,  as  each expansion is encountered left to right in the outer
       expression.

       A further complication arises from a way in which subscript parsing is not different  from
       double  quote  parsing.	As in true double-quoting, the sequences `\*', and `\@' remain as
       two characters when they appear in a subscript expression.  To use a literal `*' or `@' as
       an associative array key, the `e' flag must be used:

	      typeset -A aa
	      aa[(e)*]=star
	      print $aa[(e)*]

       A  last	detail	must  be  considered  when reverse subscripting is performed.  Parameters
       appearing in the subscript expression are first expanded and then the complete  expression
       is  interpreted	as  a  pattern.   This	has  two  effects: first, parameters behave as if
       GLOB_SUBST were on (and it cannot be turned  off);  second,  backslashes  are  interpreted
       twice,  once  when  parsing  the array subscript and again when parsing the pattern.  In a
       reverse subscript, it's necessary to use four backslashes to cause a single  backslash  to
       match  literally  in the pattern.  For complex patterns, it is often easiest to assign the
       desired pattern to a parameter and then refer to that parameter in the subscript,  because
       then the backslashes, brackets, parentheses, etc., are seen only when the complete expres-
       sion is converted to a pattern.	To match the value of a parameter literally in a  reverse
       subscript,  rather  than  as  a	pattern,  use  `${(q)name}' (see zshexpn(1)) to quote the
       expanded value.

       Note that the `k' and `K' flags are reverse subscripting for an ordinary  array,  but  are
       not reverse subscripting for an associative array!  (For an associative array, the keys in
       the array itself are interpreted as patterns by those flags;  the  subscript  is  a  plain
       string in that case.)

       One  final  note,  not  directly  related to subscripting: the numeric names of positional
       parameters (described below) are parsed specially, so for example `$2foo' is equivalent to
       `${2}foo'.   Therefore,	to  use subscript syntax to extract a substring from a positional
       parameter, the expansion must be surrounded by braces; for example, `${2[3,5]}'	evaluates
       to the third through fifth characters of the second positional parameter, but `$2[3,5]' is
       the entire second parameter concatenated with the filename generation pattern `[3,5]'.

POSITIONAL PARAMETERS
       The positional parameters provide access to the command-line arguments of  a  shell  func-
       tion,  shell  script, or the shell itself; see the section `Invocation', and also the sec-
       tion `Functions'.  The parameter n, where n is a number, is the nth positional  parameter.
       The  parameters	*,  @  and argv are arrays containing all the positional parameters; thus
       `$argv[n]', etc., is equivalent to simply `$n'.

       Positional parameters may be changed after the shell or function starts by using  the  set
       builtin,  by  assigning	to  the argv array, or by direct assignment of the form `n=value'
       where n is the number of the positional parameter to be changed.  This also creates  (with
       empty  values)  any  of	the  positions from 1 to n that do not already have values.  Note
       that, because the positional parameters form an array, an array	assignment  of	the  form
       `n=(value  ...)'  is  allowed,  and has the effect of shifting all the values at positions
       greater than n by as many positions as necessary to accommodate the new values.

LOCAL PARAMETERS
       Shell function executions delimit scopes for shell parameters.	(Parameters  are  dynami-
       cally scoped.)  The typeset builtin, and its alternative forms declare, integer, local and
       readonly (but not export), can be used to declare a parameter as being local to the inner-
       most scope.

       When  a parameter is read or assigned to, the innermost existing parameter of that name is
       used.  (That is, the local parameter hides any less-local parameter.)  However,	assigning
       to  a  non-existent  parameter,	or declaring a new parameter with export, causes it to be
       created in the outermost scope.

       Local parameters disappear when their scope ends.  unset can be used to delete a parameter
       while it is still in scope; any outer parameter of the same name remains hidden.

       Special	parameters  may  also  be made local; they retain their special attributes unless
       either the existing or the newly-created parameter has the -h (hide) attribute.	This  may
       have  unexpected  effects:  there is no default value, so if there is no assignment at the
       point the variable is made local, it will be set to an empty value (or zero in the case of
       integers).  The following:

	      typeset PATH=/new/directory:$PATH

       is  valid for temporarily allowing the shell or programmes called from it to find the pro-
       grams in /new/directory inside a function.

       Note that the restriction in older versions  of	zsh  that  local  parameters  were  never
       exported has been removed.

PARAMETERS SET BY THE SHELL
       The following parameters are automatically set by the shell:

       ! <S>  The  process  ID	of the last command started in the background with &, or put into
	      the background with the bg builtin.

       # <S>  The number of positional parameters in decimal.  Note that some confusion may occur
	      with the syntax $#param which substitutes the length of param.  Use ${#} to resolve
	      ambiguities.  In particular, the sequence `$#-...' in an arithmetic  expression  is
	      interpreted as the length of the parameter -, q.v.

       ARGC <S> <Z>
	      Same as #.

       $ <S>  The  process ID of this shell.  Note that this indicates the original shell started
	      by invoking zsh; all processes forked from the shells without executing a new  pro-
	      gram, such as subshells started by (...), substitute the same value.

       - <S>  Flags supplied to the shell on invocation or by the set or setopt commands.

       * <S>  An array containing the positional parameters.

       argv <S> <Z>
	      Same  as *.  Assigning to argv changes the local positional parameters, but argv is
	      not itself a local parameter.  Deleting argv with unset in any function deletes  it
	      everywhere, although only the innermost positional parameter array is deleted (so *
	      and @ in other scopes are not affected).

       @ <S>  Same as argv[@], even when argv is not set.

       ? <S>  The exit status returned by the last command.

       0 <S>  The name used to invoke the current shell.  If the FUNCTION_ARGZERO option is  set,
	      this  is	set  temporarily within a shell function to the name of the function, and
	      within a sourced script to the name of the script.

       status <S> <Z>
	      Same as ?.

       pipestatus <S> <Z>
	      An array containing the exit statuses returned by all commands in  the  last  pipe-
	      line.

       _ <S>  The  last  argument  of  the  previous command.  Also, this parameter is set in the
	      environment of every command executed to the full pathname of the command.

       CPUTYPE
	      The machine type (microprocessor class or machine  model),  as  determined  at  run
	      time.

       EGID <S>
	      The  effective  group  ID of the shell process.  If you have sufficient privileges,
	      you may change the effective group ID of the shell process  by  assigning  to  this
	      parameter.   Also  (assuming sufficient privileges), you may start a single command
	      with a different effective group ID by `(EGID=gid; command)'

       EUID <S>
	      The effective user ID of the shell process.  If you have sufficient privileges, you
	      may  change the effective user ID of the shell process by assigning to this parame-
	      ter.  Also (assuming sufficient privileges), you may start a single command with	a
	      different effective user ID by `(EUID=uid; command)'

       ERRNO <S>
	      The  value  of errno (see errno(3)) as set by the most recently failed system call.
	      This value is system dependent and is intended for debugging purposes.  It is  also
	      useful  with the zsh/system module which allows the number to be turned into a name
	      or message.

       GID <S>
	      The real group ID of the shell process.  If you have sufficient privileges, you may
	      change  the  group  ID  of  the shell process by assigning to this parameter.  Also
	      (assuming sufficient privileges), you may start a single command under a	different
	      group ID by `(GID=gid; command)'

       HISTCMD
	      The  current  history  line number in an interactive shell, in other words the line
	      number for the command that caused $HISTCMD to be read.

       HOST   The current hostname.

       LINENO <S>
	      The line number of the current line within the current  script,  sourced	file,  or
	      shell  function  being executed, whichever was started most recently.  Note that in
	      the case of shell functions the line number refers to the function as  it  appeared
	      in the original definition, not necessarily as displayed by the functions builtin.

       LOGNAME
	      If  the  corresponding  variable	is not set in the environment of the shell, it is
	      initialized to the login name corresponding to  the  current  login  session.  This
	      parameter  is  exported  by  default  but  this  can  be disabled using the typeset
	      builtin.

       MACHTYPE
	      The machine type (microprocessor class or machine model), as determined at  compile
	      time.

       OLDPWD The  previous  working directory.  This is set when the shell initializes and when-
	      ever the directory changes.

       OPTARG <S>
	      The value of the last option argument processed by the getopts command.

       OPTIND <S>
	      The index of the last option argument processed by the getopts command.

       OSTYPE The operating system, as determined at compile time.

       PPID <S>
	      The process ID of the parent of the shell.  As for $$, the value indicates the par-
	      ent of the original shell and does not change in subshells.

       PWD    The present working directory.  This is set when the shell initializes and whenever
	      the directory changes.

       RANDOM <S>
	      A pseudo-random integer from 0 to 32767, newly generated each time  this	parameter
	      is  referenced.	The  random number generator can be seeded by assigning a numeric
	      value to RANDOM.

	      The values of RANDOM form an intentionally-repeatable pseudo-random sequence;  sub-
	      shells  that  reference RANDOM will result in identical pseudo-random values unless
	      the value of RANDOM is referenced or seeded in the parent shell in between subshell
	      invocations.

       SECONDS <S>
	      The  number  of  seconds	since  shell invocation.  If this parameter is assigned a
	      value, then the value returned upon reference will be the value that  was  assigned
	      plus the number of seconds since the assignment.

	      Unlike  other  special parameters, the type of the SECONDS parameter can be changed
	      using the typeset command.  Only integer and one of the floating	point  types  are
	      allowed.	 For  example,	`typeset -F SECONDS' causes the value to be reported as a
	      floating point number.  The value is available to  microsecond  accuracy,  although
	      the  shell  may show more or fewer digits depending on the use of typeset.  See the
	      documentation for the builtin typeset in zshbuiltins(1) for more details.

       SHLVL <S>
	      Incremented by one each time a new shell is started.

       signals
	      An array containing the names of the signals.

       TRY_BLOCK_ERROR <S>
	      In an always block, indicates whether the preceding list of code caused  an  error.
	      The  value  is  1 to indicate an error, 0 otherwise.  It may be reset, clearing the
	      error condition.	See Complex Commands in zshmisc(1)

       TTY    The name of the tty associated with the shell, if any.

       TTYIDLE <S>
	      The idle time of the tty associated with the shell in seconds or -1 if there is  no
	      such tty.

       UID <S>
	      The  real user ID of the shell process.  If you have sufficient privileges, you may
	      change the user ID of the shell by assigning to  this  parameter.   Also	(assuming
	      sufficient privileges), you may start a single command under a different user ID by
	      `(UID=uid; command)'

       USERNAME <S>
	      The username corresponding to the real user ID of the shell process.  If	you  have
	      sufficient  privileges, you may change the username (and also the user ID and group
	      ID) of the shell by assigning to this parameter.	Also (assuming sufficient  privi-
	      leges),  you may start a single command under a different username (and user ID and
	      group ID) by `(USERNAME=username; command)'

       VENDOR The vendor, as determined at compile time.

       zsh_eval_context <S> <Z> (ZSH_EVAL_CONTEXT <S>)
	      An array (colon-separated list) indicating the context of shell code that is  being
	      run.  Each time a piece of shell code that is stored within the shell is executed a
	      string is temporarily appended to the array to indicate the type of operation  that
	      is  being  performed.   Read in order the array gives an indication of the stack of
	      operations being performed with the most immediate context last.

	      Note that the variable does not give information on syntactic context such as pipe-
	      lines or subshells.  Use $ZSH_SUBSHELL to detect subshells.

	      The context is one of the following:
	      cmdarg Code specified by the -c option to the command line that invoked the shell.

	      cmdsubst
		     Command substitution using the `...` or $(...) construct.

	      equalsubst
		     File substitution using the =(...) construct.

	      eval   Code executed by the eval builtin.

	      evalautofunc
		     Code  executed  with  the	KSH_AUTOLOAD  mechanism  in  order  to	define an
		     autoloaded function.

	      fc     Code from the shell history executed by the -e option to the fc builtin.

	      file   Lines of code being read directly from a file, for  example  by  the  source
		     builtin.

	      filecode
		     Lines  of	code  being  read  from  a .zwc file instead of directly from the
		     source file.

	      globqual
		     Code executed by the e or + glob qualifier.

	      globsort
		     Code executed to order files by the o glob qualifier.

	      insubst
		     File substitution using the <(...) construct.

	      loadautofunc
		     Code read directly from a file to define an autoloaded function.

	      outsubst
		     File substitution using the >(...) construct.

	      sched  Code executed by the sched builtin.

	      shfunc A shell function.

	      stty   Code passed to stty by the STTY  environment  variable.   Normally  this  is
		     passed  directly  to the system's stty command, so this value is unlikely to
		     be seen in practice.

	      style  Code executed as part of a style retrieved by the zstyle  builtin	from  the
		     zsh/zutil module.

	      toplevel
		     The highest execution level of a script or interactive shell.

	      trap   Code executed as a trap defined by the trap builtin.  Traps defined as func-
		     tions have the context shfunc.  As traps are asynchronous they  may  have	a
		     different hierarchy from other code.

	      zpty   Code executed by the zpty builtin from the zsh/zpty module.

	      zregexparse-guard
		     Code  executed as a guard by the zregexparse command from the zsh/zutil mod-
		     ule.

	      zregexparse-action
		     Code executed as an action by the zregexparse  command  from  the	zsh/zutil
		     module.

       ZSH_NAME
	      Expands to the basename of the command used to invoke this instance of zsh.

       ZSH_PATCHLEVEL
	      The revision string for the version number of the ChangeLog file in the zsh distri-
	      bution.  This is most useful in order to keep track of versions of the shell during
	      development between releases; hence most users should not use it and should instead
	      rely on $ZSH_VERSION.

       zsh_scheduled_events
	      See the section `The zsh/sched Module' in zshmodules(1).

       ZSH_SUBSHELL
	      Readonly integer.  Initially zero, incremented each time the shell forks to  create
	      a  subshell  for	executing code.  Hence `(print $ZSH_SUBSHELL)' and `print $(print
	      $ZSH_SUBSHELL)' output 1, while `( (print $ZSH_SUBSHELL) )' outputs 2.

       ZSH_VERSION
	      The version number of the release of zsh.

PARAMETERS USED BY THE SHELL
       The following parameters are used by the shell.

       In cases where there are two parameters with an upper- and  lowercase  form  of	the  same
       name,  such  as	path and PATH, the lowercase form is an array and the uppercase form is a
       scalar with the elements of the array joined together by colons.   These  are  similar  to
       tied  parameters created via `typeset -T'.  The normal use for the colon-separated form is
       for exporting to the environment, while the array form is easier to manipulate within  the
       shell.	Note  that  unsetting  either of the pair will unset the other; they retain their
       special properties when recreated, and recreating one of the pair will recreate the other.

       ARGV0  If exported, its value is used as the argv[0] of external commands.   Usually  used
	      in constructs like `ARGV0=emacs nethack'.

       BAUD   The  rate  in  bits per second at which data reaches the terminal.  The line editor
	      will use this value in order to compensate for a slow terminal by delaying  updates
	      to the display until necessary.  If the parameter is unset or the value is zero the
	      compensation mechanism is turned off.  The parameter is not set by default.

	      This parameter may be profitably set in some circumstances, e.g.	for  slow  modems
	      dialing into a communications server, or on a slow wide area network.  It should be
	      set to the baud rate of the slowest part of the link for best performance.

       cdpath <S> <Z> (CDPATH <S>)
	      An array (colon-separated list) of directories specifying the search path  for  the
	      cd command.

       COLUMNS <S>
	      The  number  of  columns for this terminal session.  Used for printing select lists
	      and for the line editor.

       CORRECT_IGNORE
	      If set, is treated as a pattern during spelling correction.  Any potential  correc-
	      tion  that  matches the pattern is ignored.  For example, if the value is `_*' then
	      completion functions (which, by convention, have names  beginning  with  `_')  will
	      never  be  offered as spelling corrections.  The pattern does not apply to the cor-
	      rection of file names, as applied by the CORRECT_ALL option (so  with  the  example
	      just  given  files  beginning with `_' in the current directory would still be com-
	      pleted).

       DIRSTACKSIZE
	      The maximum size of the directory stack, by default there  is  no  limit.   If  the
	      stack  gets  larger  than this, it will be truncated automatically.  This is useful
	      with the AUTO_PUSHD option.

       ENV    If the ENV environment variable is set when zsh is invoked as sh or  ksh,  $ENV  is
	      sourced  after  the  profile  scripts.   The value of ENV is subjected to parameter
	      expansion, command substitution, and arithmetic expansion before being  interpreted
	      as a pathname.  Note that ENV is not used unless zsh is emulating sh or ksh.

       FCEDIT The  default editor for the fc builtin.  If FCEDIT is not set, the parameter EDITOR
	      is used; if that is not set either, a builtin default, usually vi, is used.

       fignore <S> <Z> (FIGNORE <S>)
	      An array (colon separated list) containing the suffixes of files to be ignored dur-
	      ing filename completion.	However, if completion only generates files with suffixes
	      in this list, then these files are completed anyway.

       fpath <S> <Z> (FPATH <S>)
	      An array (colon separated list) of directories specifying the search path for func-
	      tion  definitions.   This path is searched when a function with the -u attribute is
	      referenced.  If an executable file is found, then it is read and	executed  in  the
	      current environment.

       histchars <S>
	      Three  characters  used by the shell's history and lexical analysis mechanism.  The
	      first character signals the start of a history expansion (default `!').  The second
	      character  signals  the  start  of a quick history substitution (default `^').  The
	      third character is the comment character (default `#').

	      The characters must be in the ASCII character set; any attempt to set histchars  to
	      characters with a locale-dependent meaning will be rejected with an error message.

       HISTCHARS <S> <Z>
	      Same as histchars.  (Deprecated.)

       HISTFILE
	      The  file  to  save  the history in when an interactive shell exits.  If unset, the
	      history is not saved.

       HISTSIZE <S>
	      The maximum number of events stored in the internal history list.  If you  use  the
	      HIST_EXPIRE_DUPS_FIRST  option,  setting	this  value larger than the SAVEHIST size
	      will give you the difference as a cushion for saving duplicated history events.

       HOME <S>
	      The default argument for the cd command.	This is  not  set  automatically  by  the
	      shell  in  sh, ksh or csh emulation, but it is typically present in the environment
	      anyway, and if it becomes set it has its usual special behaviour.

       IFS <S>
	      Internal field separators (by default space, tab, newline and NUL), that	are  used
	      to  separate  words which result from command or parameter expansion and words read
	      by the read builtin.  Any characters from the  set  space,  tab  and  newline  that
	      appear  in the IFS are called IFS white space.  One or more IFS white space charac-
	      ters 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.

	      If  the  parameter is unset, the default is used.  Note this has a different effect
	      from setting the parameter to an empty string.

       KEYBOARD_HACK
	      This variable defines a character to be removed from the end of  the  command  line
	      before interpreting it (interactive shells only). It is intended to fix the problem
	      with keys placed annoyingly close to return and replaces the SUNKEYBOARDHACK option
	      which  did this for backquotes only.  Should the chosen character be one of single-
	      quote, doublequote or backquote, there must also be an odd number of  them  on  the
	      command line for the last one to be removed.

	      For  backward  compabitility,  if the SUNKEYBOARDHACK option is explicitly set, the
	      value of KEYBOARD_HACK reverts to backquote.  If the option  is  explicitly  unset,
	      this variable is set to empty.

       KEYTIMEOUT
	      The  time  the shell waits, in hundredths of seconds, for another key to be pressed
	      when reading bound multi-character sequences.

       LANG <S>
	      This variable determines the locale category  for  any  category	not  specifically
	      selected via a variable starting with `LC_'.

       LC_ALL <S>
	      This  variable  overrides  the value of the `LANG' variable and the value of any of
	      the other variables starting with `LC_'.

       LC_COLLATE <S>
	      This variable determines the locale category for	character  collation  information
	      within ranges in glob brackets and for sorting.

       LC_CTYPE <S>
	      This  variable determines the locale category for character handling functions.  If
	      the MULTIBYTE option is in effect this variable or LANG should contain a value that
	      reflects	the  character	set  in  use,  even if it is a single-byte character set,
	      unless only the 7-bit subset (ASCII) is used.  For example, if the character set is
	      ISO-8859-1,  a suitable value might be en_US.iso88591 (certain Linux distributions)
	      or en_US.ISO8859-1 (MacOS).

       LC_MESSAGES <S>
	      This variable determines the language in which messages should  be  written.   Note
	      that zsh does not use message catalogs.

       LC_NUMERIC <S>
	      This variable affects the decimal point character and thousands separator character
	      for the formatted input/output functions and  string  conversion	functions.   Note
	      that zsh ignores this setting when parsing floating point mathematical expressions.

       LC_TIME <S>
	      This variable determines the locale category for date and time formatting in prompt
	      escape sequences.

       LINES <S>
	      The number of lines for this terminal session.  Used for printing select lists  and
	      for the line editor.

       LISTMAX
	      In  the  line  editor,  the  number of matches to list without asking first. If the
	      value is negative, the list will be shown if it spans at	most  as  many	lines  as
	      given by the absolute value.  If set to zero, the shell asks only if the top of the
	      listing would scroll off the screen.

       LOGCHECK
	      The interval in seconds between checks for login/logout activity	using  the  watch
	      parameter.

       MAIL   If  this	parameter is set and mailpath is not set, the shell looks for mail in the
	      specified file.

       MAILCHECK
	      The interval in seconds between checks for new mail.

       mailpath <S> <Z> (MAILPATH <S>)
	      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 expansion with the
	      variable	$_ defined as the name of the file that has changed.  The default message
	      is `You have new mail'.  If an element is a directory instead of a file  the  shell
	      will recursively check every file in every subdirectory of the element.

       manpath <S> <Z> (MANPATH <S> <Z>)
	      An  array (colon-separated list) whose value is not used by the shell.  The manpath
	      array can be useful, however, since setting it also sets MANPATH, and vice versa.

       match
       mbegin
       mend   Arrays set by the shell when the b globbing flag is used in pattern  matches.   See
	      the  subsection Globbing flags in the documentation for Filename Generation in zsh-
	      expn(1).

       MATCH
       MBEGIN
       MEND   Set by the shell when the m globbing flag is used in pattern matches.  See the sub-
	      section Globbing flags in the documentation for Filename Generation in zshexpn(1).

       module_path <S> <Z> (MODULE_PATH <S>)
	      An  array  (colon-separated list) of directories that zmodload searches for dynami-
	      cally loadable modules.  This  is  initialized  to  a  standard  pathname,  usually
	      `/usr/local/lib/zsh/$ZSH_VERSION'.   (The `/usr/local/lib' part varies from instal-
	      lation to installation.)	For security reasons, any value set  in  the  environment
	      when the shell is started will be ignored.

	      These parameters only exist if the installation supports dynamic module loading.

       NULLCMD <S>
	      The command name to assume if a redirection is specified with no command.  Defaults
	      to cat.  For sh/ksh behavior, change this to :.  For csh-like behavior, unset  this
	      parameter; the shell will print an error message if null commands are entered.

       path <S> <Z> (PATH <S>)
	      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.

       POSTEDIT <S>
	      This  string is output whenever the line editor exits.  It usually contains termcap
	      strings to reset the terminal.

       PROMPT <S> <Z>
       PROMPT2 <S> <Z>
       PROMPT3 <S> <Z>
       PROMPT4 <S> <Z>
	      Same as PS1, PS2, PS3 and PS4, respectively.

       prompt <S> <Z>
	      Same as PS1.

       PROMPT_EOL_MARK
	      When the PROMPT_CR and PROMPT_SP options are set, the PROMPT_EOL_MARK parameter can
	      be used to customize how the end of partial lines are shown.  This parameter under-
	      goes prompt expansion, with the PROMPT_PERCENT option set.  If not set, the default
	      behavior is equivalent to the value `%B%S%#%s%b'.

       PS1 <S>
	      The  primary  prompt string, printed before a command is read.  It undergoes a spe-
	      cial form of expansion before being displayed; see EXPANSION OF PROMPT SEQUENCES in
	      zshmisc(1).  The default is `%m%# '.

       PS2 <S>
	      The  secondary  prompt, printed when the shell needs more information to complete a
	      command.	It is expanded in the same way as PS1.	The default is `%_> ', which dis-
	      plays any shell constructs or quotation marks which are currently being processed.

       PS3 <S>
	      Selection prompt used within a select loop.  It is expanded in the same way as PS1.
	      The default is `?# '.

       PS4 <S>
	      The execution trace prompt.  Default is `+%N:%i> ', which displays the name of  the
	      current shell structure and the line number within it.  In sh or ksh emulation, the
	      default is `+ '.

       psvar <S> <Z> (PSVAR <S>)
	      An array (colon-separated list) whose first nine	values	can  be  used  in  PROMPT
	      strings.	Setting psvar also sets PSVAR, and vice versa.

       READNULLCMD <S>
	      The  command name to assume if a single input redirection is specified with no com-
	      mand.  Defaults to more.

       REPORTTIME
	      If nonnegative, commands whose combined user and system execution  times	(measured
	      in  seconds)  are  greater than this value have timing statistics printed for them.
	      Output is suppressed for commands executed within the line editor,  including  com-
	      pletion;	commands  explicitly marked with the time keyword still cause the summary
	      to be printed in this case.

       REPLY  This parameter is reserved by  convention  to  pass  string  values  between  shell
	      scripts  and  shell builtins in situations where a function call or redirection are
	      impossible or undesirable.  The read builtin and the select complex command may set
	      REPLY,  and  filename  generation  both sets and examines its value when evaluating
	      certain expressions.  Some modules also employ REPLY for similar purposes.

       reply  As REPLY, but for array values rather than strings.

       RPROMPT <S>
       RPS1 <S>
	      This prompt is displayed on the right-hand side of  the  screen  when  the  primary
	      prompt  is  being displayed on the left.	This does not work if the SINGLE_LINE_ZLE
	      option is set.  It is expanded in the same way as PS1.

       RPROMPT2 <S>
       RPS2 <S>
	      This prompt is displayed on the right-hand side of the screen  when  the	secondary
	      prompt  is  being displayed on the left.	This does not work if the SINGLE_LINE_ZLE
	      option is set.  It is expanded in the same way as PS2.

       SAVEHIST
	      The maximum number of history events to save in the history file.

       SPROMPT <S>
	      The prompt used for spelling correction.	The sequence `%R' expands to  the  string
	      which  presumably  needs spelling correction, and `%r' expands to the proposed cor-
	      rection.	All other prompt escapes are also allowed.

       STTY   If this parameter is set in a command's environment, the shell runs the  stty  com-
	      mand  with the value of this parameter as arguments in order to set up the terminal
	      before executing the command. 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 fg or wait 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.

       TERM <S>
	      The type of terminal in use.  This is used when looking up termcap  sequences.   An
	      assignment to TERM causes zsh to re-initialize the terminal, even if the value does
	      not change (e.g., `TERM=$TERM').	It is necessary to make such an  assignment  upon
	      any  change  to  the terminal definition database or terminal type in order for the
	      new settings to take effect.

       TERMINFO <S>
	      A reference to a compiled description of	the  terminal,	used  by  the  `terminfo'
	      library  when the system has it; see terminfo(5).  If set, this causes the shell to
	      reinitialise the terminal, making the workaround `TERM=$TERM' unnecessary.

       TIMEFMT
	      The format of process time reports with the time keyword.  The default is  `%J   %U
	      user  %S	system	%P  cpu  %*E  total'.  Recognizes the following escape sequences,
	      although not all may be available on all systems, and some that are  available  may
	      not be useful:

	      %%     A `%'.
	      %U     CPU seconds spent in user mode.
	      %S     CPU seconds spent in kernel mode.
	      %E     Elapsed time in seconds.
	      %P     The CPU percentage, computed as (100*%U+%S)/%E.
	      %W     Number of times the process was swapped.
	      %X     The average amount in (shared) text space used in kilobytes.
	      %D     The average amount in (unshared) data/stack space used in kilobytes.
	      %K     The total space used (%X+%D) in kilobytes.
	      %M     The  maximum memory the process had in use at any time in megabytes.
	      %F     The number of major page faults (page needed to be brought from disk).
	      %R     The number of minor page faults.
	      %I     The number of input operations.
	      %O     The number of output operations.
	      %r     The number of socket messages received.
	      %s     The number of socket messages sent.
	      %k     The number of signals received.
	      %w     Number of voluntary context switches (waits).
	      %c     Number of involuntary context switches.
	      %J     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).

       TMOUT  If this parameter is nonzero, the shell will receive an ALRM signal if a command is
	      not entered within the specified number of seconds after issuing a prompt. If there
	      is  a  trap  on SIGALRM, it will be executed and a new alarm is scheduled using the
	      value of the TMOUT parameter after executing the trap.  If no trap is set, and  the
	      idle  time  of  the terminal is not less than the value of the TMOUT parameter, zsh
	      terminates.  Otherwise a new alarm is scheduled to TMOUT	seconds  after	the  last
	      keypress.

       TMPPREFIX
	      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'.

       watch <S> <Z> (WATCH <S>)
	      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.  If  it  contains
	      the  single  word `notme', then all events are reported as with `all' except $USER-
	      NAME.  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.

       WATCHFMT
	      The  format  of login/logout reports if the watch parameter is set.  Default is `%n
	      has %a %l from %m'.  Recognizes the following escape sequences:

	      %n     The name of the user that logged in/out.

	      %a     The observed action, i.e. "logged on" or "logged off".

	      %l     The line (tty) the user is logged in on.

	      %M     The full hostname of the remote host.

	      %m     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.

		     NOTE: 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.

	      %S (%s)
		     Start (stop) standout mode.

	      %U (%u)
		     Start (stop) underline mode.

	      %B (%b)
		     Start (stop) boldface mode.

	      %t
	      %@     The time, in 12-hour, am/pm format.

	      %T     The time, in 24-hour format.

	      %w     The date in `day-dd' format.

	      %W     The date in `mm/dd/yy' format.

	      %D     The date in `yy-mm-dd' format.

	      %(x:true-text:false-text)
		     Specifies a ternary expression.  The character following the x 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 x may be any one of `l', `n', `m' or `M', which indicate
		     a `true'  result  if  the	corresponding  escape  sequence  would	return	a
		     non-empty	value;	or  it may be `a', which indicates a `true' result if the
		     watched user has logged in, or `false' if he has logged out.  Other  charac-
		     ters evaluate to neither true nor false; the entire expression is omitted in
		     this case.

		     If the result is `true', then the true-text is formatted  according  to  the
		     rules  above  and	printed,  and the false-text is skipped.  If `false', the
		     true-text is skipped and the false-text is formatted and printed.	Either or
		     both  of  the  branches may be empty, but both separators must be present in
		     any case.

       WORDCHARS <S>
	      A list of non-alphanumeric characters considered part of a word by the line editor.

       ZBEEP  If set, this gives a string of characters, which can use all the same codes as  the
	      bindkey  command	as  described  in the zsh/zle module entry in zshmodules(1), that
	      will be output to the terminal instead of beeping.  This may have a visible instead
	      of  an  audible  effect; for example, the string `\e[?5h\e[?5l' on a vt100 or xterm
	      will have the effect of flashing reverse video on  and  off  (if	you  usually  use
	      reverse  video,  you  should  use  the  string `\e[?5l\e[?5h' instead).  This takes
	      precedence over the NOBEEP option.

       ZDOTDIR
	      The directory to search for shell startup files (.zshrc, etc), if not $HOME.

       ZLE_LINE_ABORTED
	      This parameter is set by the line editor when an error  occurs.	It  contains  the
	      line   that   was  being	edited	at  the  point	of  the  error.   `print  -zr  --
	      $ZLE_LINE_ABORTED' can be used to recover the line.  Only the most recent  line  of
	      this kind is remembered.

       ZLE_REMOVE_SUFFIX_CHARS
       ZLE_SPACE_SUFFIX_CHARS
	      These  parameters  are  used by the line editor.	In certain circumstances suffixes
	      (typically space or slash) added by the completion system will be removed automati-
	      cally,  either because the next editing command was not an insertable character, or
	      because the character was marked as requiring the suffix to be removed.

	      These variables can contain the sets of characters that will cause the suffix to be
	      removed.	If ZLE_REMOVE_SUFFIX_CHARS is set, those characters will cause the suffix
	      to be removed; if ZLE_SPACE_SUFFIX_CHARS is set, those characters  will  cause  the
	      suffix to be removed and replaced by a space.

	      If ZLE_REMOVE_SUFFIX_CHARS is not set, the default behaviour is equivalent to:

		     ZLE_REMOVE_SUFFIX_CHARS=$' \t\n;&|'

	      If  ZLE_REMOVE_SUFFIX_CHARS is set but is empty, no characters have this behaviour.
	      ZLE_SPACE_SUFFIX_CHARS takes precedence, so that the following:

		     ZLE_SPACE_SUFFIX_CHARS=$'&|'

	      causes the characters `&' and `|' to remove the suffix but to  replace  it  with	a
	      space.

	      To  illustrate  the  difference,	suppose  that  the option AUTO_REMOVE_SLASH is in
	      effect and the directory DIR has just been completed, with an appended /, following
	      which  the  user	types  `&'.   The default result is `DIR&'.  With ZLE_REMOVE_SUF-
	      FIX_CHARS set but without including `&' the result is `DIR/&'.  With ZLE_SPACE_SUF-
	      FIX_CHARS set to include `&' the result is `DIR &'.

	      Note  that  certain completions may provide their own suffix removal or replacement
	      behaviour which overrides the values described here.   See  the  completion  system
	      documentation in zshcompsys(1).
