A recent
release change log
is also included.
KSH-93 is the most recent version of the KornShell Language
described in
"The KornShell Command and Programming Language,"
by Morris Bolsky and David Korn of AT&T Bell Laboratories, ISBN 0-13-182700-6.
The KornShell is a shell programming language,
which is upward compatible with "sh" (the Bourne Shell),
and is intended to conform to the IEEE P1003.2/ISO 9945.2 Shell and
Utilities standard.
KSH-93 provides an enhanced programming environment in
addition to the major command-entry features of the BSD
shell "csh". With KSH-93, medium-sized programming tasks can be
performed at shell-level without a significant loss in performance.
In addition, "sh" scripts can be run on KSH-93 without modification.
The code should conform to the IEEE POSIX 1003.1 standard and to the
proposed ANSI-C standard so that it should be portable to all
such systems. Like the previous version, KSH-88,
it is designed to accept eight bit character sets
transparently, thereby making it internationally compatible.
It can support multi-byte characters sets with some characteristics
of the character set given at run time.
KSH-93 provides the following features, many of which were also inherent
in KSH-88:
-
Enhanced Command Re-entry Capability: The KSH-93 history
function records commands entered at any shell level and stores
them, up to a user-specified limit, even after you log off.
This allows you to re-enter long commands with a few keystrokes
- even those commands you entered yesterday.
The history file allows for eight bit characters in
commands and supports essentially unlimited size histories.
-
In-line Editing: In "sh", the only way to fix mistyped
commands is to backspace or retype the line. KSH-93 allows you
to edit a command line using a choice of EMACS-TC or "vi"
functions.
You can use the in-line editors to complete filenames as
you type them.
You may also use this editing feature when entering
command lines from your history file.
A user can capture keystrokes and rebind keys to customize the
editing interface.
-
Extended I/O Capabilities: KSH-93 provides several I/O
capabilities not available in "sh", including the ability to:
-
specify a file descriptor for input and output
-
start up and run co-processes
-
produce a prompt at the terminal before a read
-
easily format and interpret responses to a menu
-
echo lines exactly as output without escape processing
-
format output using printf formats.
-
read and echo lines ending in "\".
-
Improved performance: KSH-93 executes many scripts faster
than the System V Bourne shell. A major reason for this is
that many of the standard utilities are built-in.
To reduce the time to initiate a command, KSH-93 allows
commands to be added as built-ins at run time
on systems that support dynamic loading such as System V Release 4.
-
Arithmetic: KSH-93 allows you to do integer arithmetic in any
base from two to sixty-four. You can also do double
precision floating point arithmetic.
Almost the complete set of C language operators are available
with the same syntax and precedence.
Arithmetic expressions can be used to as an argument expansion
or as a separate command.
In addition there is an arithmetic for command that works
like the for statement in C.
-
Arrays: KSH-93 supports both indexed and associative arrays.
The subscript for an indexed array is an arithmetic expression,
whereas, the subscript for an associative array is a string.
-
Shell Functions and Aliases: Two mechanisms - functions and
aliases - can be used to assign a user-selected identifier to
an existing command or shell script.
Functions allow local variables and provide scoping
for exception handling.
Functions can be searched for and loaded on first reference the
way scripts are.
-
Substring Capabilities: KSH-93 allows you to create a
substring of any given string either by specifying the starting
offset and length, or by stripping off leading
or trailing substrings during parameter substitution.
You can also specify attributes, such as upper and lower case,
field width, and justification to shell variables.
-
More pattern matching capabilities: KSH-93 allows you to specify
extended regular expressions for file and string matches.
-
KSH-93 uses a hierarchal name space for variables.
Compound variables can be defined and variables can
be passed by reference. In addition, each variable
can have one or more disciplines associated with
it to intercept assignments and references.
-
Improved debugging: KSH-93 can generate line numbers on execution
traces. Also, I/O redirections are now traced.
There is a DEBUG trap that gets evaluated after each command
so that errors can be localized.
-
Job Control: On systems that support job control, including
System V Release 4, KSH-93
provides a job-control mechanism almost identical to that of
the BSD "csh", version 4.1.
This feature allows you
to stop and restart programs, and to move programs between the
foreground and the background.
-
Added security:
KSH-93 can execute scripts which do not have read permission
and scripts which have the setuid and/or setgid set when
invoked by name, rather than as an argument to the shell.
It is possible to log or control the execution of setuid and/or
setgid scripts.
The noclobber option prevents you from accidentally erasing
a file by redirecting to an existing file.
-
KSH-93 can be extended by adding built-in commands at run time.
In addition, KSH-93 can be used as a library that can
be embedded into an application to allow scripting.
Documentation for KSH-93 consists of an "Introduction to KSH-93",
"Compatibility with the Bourne Shell" and a manual page and a
README file. In addition, the "New KornShell Command and Programming
Language," book is available from Prentice Hall.

multiple word replacements with the . directive has been fixed.
04-01-06 Backspace characters are now handled correctly in prompt strings.
04-01-06 The getopts builtin has been modified to accept numerical

of acquiring more space has been fixed.
03-12-05 If ENV is not specified, the shell will default to $HOME/.kshrc
for interactive shells.
03-11-21 A bug introduced in ksh93o in which the DEBUG trap could get
disabled after it triggered has been fixed.
03-11-04 A bug in which using arithetic prefix opertors ++ or -- on a
non-lvalue could cause a core dump has been fixed.
03-11-04 A bug in which leading zeros were stripped from variable
expansions within arithmetic compution to avoid being treated

03-10-08 A bug introduced in ksh93o in which a large here document inside
a function definition could get corrupted has been fixed.
03-09-22 A bug in which the .get discipline function was not being
called when a string variable was implictly referenced from
within a numerical expression has been fixed.
03-09-22 A bug in which a script without a leading #! could get executed
by /bin/sh rather than the current shell on some systems has
been fixed.
03-09-12 To improve conformance with ksh88, leading zeros will be ignored
when getting the numerical value of a string variable so that
they will not be treated as octal constants.

any number of arguments can be specified.
03-06-14 A bug in which could cause a core dump on some systems with
vi and emacs editors with the MULTIBYTE option has been fixed.

03-05-30 A bug in which the PATH search could give incorrect results when
run from directory foo and PATH contained .:foo:xxx has been fixed.
03-05-29 Some changes were made to the code that displays the prompt in edit
mode to better handle escape sequences in the prompt.
03-05-27 I added = to the list of characters that mark the beginning of
a word for edit completion so that filenames in assignments
can be completed.
03-05-20 A bug in which read -N could hang on some systems when reading
from a terminal or a pipe has been fixed.
03-05-19 A bug in which the ouput of uname from a command substitution
would go to the standard output of the invoking command when
uname was invoked with a non-standard option has been fixed.

it hadn't take back the terminal has been fixed. The bug
could occur when running a function that contained a pipeline
whose last element was a function.
03-05-19 A job control timing bug introduced in ksh93o on some systems
which could cause a pipeline to hang if the first component
completed quickly has been fixed.
03-05-13 The read builtin has been modified so that the builtin editors
will not overwrite output from a previous incomplete line.
03-05-13 A bug in which the name of an identifier could have the string
.sh. prefixed to it after expanding a variable whose name begins

03-05-08 The last item in the ksh93o release on 03-01-02 has been
altered sligthly to preserve the leading 0's when the
preceding character is a digit. Thus, with typeset -LZ3 x=10,
$(( 1$x)) will be 1010 whereas $(( $x) will be 10.
03-04-25 A bug in which if x is a name reference, then nameref y=x.foo
did not follow x has been fixed.
03-03-18 --- Release ksh93o ---
03-03-18 A -N unary operator was added to test and [[...]] which returns
true if the file exists and the file has been modified since it
was last read.
03-03-18 The TIMEFORMAT variable was added to control the format for
the time compound command. The formatting description is
described in the man page.
03-03-06 A -N n option was added to read which causes exactly n bytes
to be read unlike -n n which causes at most n bytes to be read.
03-03-03 Three new shell variables were added. The variable .sh.file
stores the full pathname of the file that the current command
was found in. The variable .sh.fun names the current function
that is running. The variable .sh.subshell contains the depth
of the current subshell or command substitution.
03-03-03 When the DEBUG trap is executed, the current command line after
expansions is placed in the variable .sh.command. The trap
is also now triggered before each iteration of a for, select,
and case command and before each assignment and redirection.
03-02-28 Function definitions are no longer stored in the history file so
that set -o nolog no longer has any meaning.
03-02-28 All function definitions can be displayed with typeset -f not
just those stored in the history file. In addition, typeset +f
displays the function name followed by a comment containg the
line number and the path name for the file that defined this function.
03-02-28 A bug in which the value of $LINENO was not correct when executing
command contained inside mult-line command substitutions has been
fixed.
03-02-19 Since some existing ksh88 scripts use the undocumented and
unintended ability to insert a : in front of the % and # parameter
expansion operators, ksh93 was modified to accept :% as equivalent
to % and :# as equivalent to # with ${name op word}.
03-02-14 A bug which could cause a core dump when reading from standard
error when standard error was a pty has been fixed.
03-02-14 The shell arithmetic was modified to use long double on systems
that provide this data type.
03-02-09 A bug in which a function located in the first directory in FPATH
would not be found when the last component of PATH was . and the
current directory was one of the directories in PATH has been fixed.
03-02-07 The trap and kill builtin commands now accept a leading SIG prefix
on the signal names as documented.
03-02-05 A bug in the expansion of ${var/$pattern}, when pattern contained
\[ has been fixed.
03-02-05 A bug in which .sh.match[n], n>0, was not being set for substring
matches with % and %% has been fixed.
03-01-15 A bug in which getopts did not work for numerical arguments specified
as n#var in the getopts string has been fixed.
03-01-09 A bug in which using ${.sh.match} multiple times could lead to
a memory exception has been fixed.
03-01-06 A bug in the expansion of ${var/pattern/$string} in the case that
$string contains \digit has been fixed.
03-01-02 A -P option was added for systems such as Solaris 8 that support
profile shell.
03-01-02 For backward compatibility with ksh88, arithmetic expansion
with ((...)) and let has been modified so that if x is a zero-filled
variable, $x will not be treated as an octal constant.
02-12-05 --- Release ksh93n+ ---
02-11-30 A bug that can show up in evaluating arithmetic statements that
are in an autoloaded function when the function is autoload from
another function has been fixed.
02-11-30 An optimization bug in which an expansion of the form ${!name.@},
which occurred inside a for or a while loop, when name is a name
reference, has been fixed.
02-11-18 A bug in which modifying array variables in a subshell could leave
side effects in the parent shell environment has been fixed.
02-11-18 A memory leak when unsetting an associative array has been fixed.
02-11-14 The code to display compound objects was rewritten to make
it easier for runtime extensions to reuse this code.
02-11-14 A change was made to allow runtime builtins to be notified when
a signal is received so that cleanup can be performed.
02-10-31 User applications can now trap the ALRM signal. Previously,
the ALRM signal was used internally and could not be used
by applications.
02-10-31 A bug in which signals received while reading from a coprocess
for which traps were set was not handled correctly has been fixed.
02-10-31 A bug in which a file opened with exec inside a subshell could
be closed before the subshell completed has been fixed.
02-10-21 A bug in which setting PATH or FPATH inside a function might not
take effect has been fixed.
02-10-21 A bug which could cause a core dump when a local SECONDS variable
is defined in a function has been fixed.
02-10-15 A bug in which the associate array name operator ${!array[@]}
could return the same name multiple times has been fixed.
02-10-15 A bug in which the zero'th element of an associative array was
not getting set when an assignment was made without a subscript
specified has been fixed.
02-09-30 --- Release ksh93n ---
02-09-30 The maximum indexed array size was increased to 16Megs.
02-09-30 A bug which could cause a core dump when changing attributes
of associative array has been fixed.
02-09-30 A bug in which exporting an array variable would not export the
0-th element has been fixed.
02-09-30 A bug in which an array assignment of the form a=($a ...) would unset
'a' before the right hand side was evaluated has been fixed.
02-09-27 A bug in which the error message for ${var?message} when var was
null or unset did not contain the variable name var has been fixed.
02-09-27 A bug in which closing file descriptors 0 through 2 could
cause a subsequent here document to fail has been fixed.

a / has been fixed.
02-09-14 A bug in the parser for strings of the form name$((expr))=value
has been fixed.
02-09-14 A for loop optimization bug in which the number of elements in
an array was treated as an invariant has been fixed.
02-09-09 A bug in which redirection or closing of a file descriptor between
3 and 9 could cause a subsequent here document to fail has been
fixed.
02-09-09 A bug in which a background job was not removed from the job list
when a subshell completed has been fixed, for example (prog&).
02-09-03 A bug in which an assignment of the form name=(integer x=3)
could be interpretted as an array assignment rather than a
compound variable assignment has been fixed.
02-08-19 A command completion bug which occurred on file systems that
are case insensitive has been fixed.
02-08-19 A bug which could lead to an exception on some systems (for
example FREEBSD) which occurred when setting PATH has been fixed.

echoing of characters by ksh when emacs or viraw mode
was enabled has been fixed.
02-06-17 A bug in which background job completion could cause the sleep
builtin to terminate prematurely has been fixed.

for multibyte character sets which occurred when a repeated search
was requested after a long line had been returned for the previous
search has been fixed.
02-04-02 vi and emacs edit modes were modified so that tab completion is
disabled when invoked from the read built-in.

02-01-07 A bug in which builtin foo, where foo is already a builtin
would result in the builtin foo getting removed has been fixed.
02-01-07 A bug which the shell executed a command found in the current
directory when PATH have no valid directories has been fixed.
01-11-28 The value of $? was not being set when called with exit.
01-11-28 If the last command was of the form (...) and a trap on EXIT or

viraw mode will always be on.
01-10-31 --- Release ksh93m ---
01-10-31 A for loop optimizer bug for subshells contained withing for
loops has been fixed.
01-10-16 typeset without arguments no longer outputs variable names

treated as invariants has been fixed.
01-09-27 Two bugs relating to multibyte history searches and to find
have been fixed.
01-09-27 A bug introduced in ksh93k in which the PATH searching was
not restored after running a command with an assignment list
has been fixed.
01-09-26 A bug in which a zero filled field was treated as octal when
converted to integer has been fixed.
01-09-26 Yet another bug in the optimization of for loops related to
recursive functions with break or continue statements has been fixed.
01-09-25 The exponentiation operator ** was added to the shell arithmetic
evaluation. It has higher precedence than * and is left
associative.
01-09-25 The code was modified to use the ast multibyte macros
and functions for handing multibyte locales.
01-09-25 The expansion ${parameter:offset:length} now handles negative
offsets which cause offsets to be measured from the end.
01-09-25 Some spelling errors in the documentation were corrected.
01-09-24 The /dev/tcp/host/port and /dev/udp/host/port now allow
the ports to be specified by service name.
01-09-24 The change staring with ksh93g in which the the appropriate
library path variable is prepended with a corresponding library
directory has been modified. With the new method, only the
library path defined in the file named .paths in the directory
where the executable is found will be modified. See the
man page for more details.
01-09-23 The .fpath file (see ksh93h) is no longer looked for in each
directory on the path to locate function directories. The
file named .paths is used instead.
01-09-23 A bug in which IFS was not being restored after being changed in
a subshell has been fixed.
01-09-16 With the vi and emacs edit modes, after a list of command
or functions is generated with = or M-= respectively,
any element from the list can be pasted on the command line
by preceding the = or M-= with a numeric parameter specifying
the position on the list.
01-09-16 A bug in ksh93l caused command completion not to find aliases
and functions. Command listing from the edit mode was presented
in reverse order. This has been fixed.
01-09-13 Another bug in the optimization of for loops related to subshells
when traps were set has been fixed.
01-09-07 A change in ksh93l caused brace expansion to stop working
and this has been fixed.
01-09-04 A bug introduced in ksh93k in which an arithmetic statement
within a function that used name references did not follow the
reference has been fixed.
01-09-04 A bug introduced in ksh93l in which export -p did not prefix
each export with the word export has been fixed.
01-08-29 A bug in multibyte input which occurred when a partial multibyte
character was received has been fixed.
01-08-29 A bug introduced in ksh93l which could cause a core dump
when an assignment list containing PATH is specified inside
command substitution has been fixed.
01-08-09 Another bug in the optimization of for loops in ksh93l caused
errors in recursive functions using local variables that
contained for loops has been fixed.
01-07-27 A bug in which IFS would be unset after a command substitution
inside a here document has been fixed.
01-07-26 To conform to the POSIX standard, if you invoked ksh name,
and name does not contain a /, it will first try to run
one in the current directory whether it is executable or not
before doing a path search for an executable script. Earlier
versions first checked for an executable script using the
PATH variable.
01-07-23 A bug in which unset -f invoked in a subshell could unset a
function defined in the parent has been fixed.
01-07-16 A bug in the optimization of for loops in ksh93l caused
name references to be treated as invariants has been fixed.
01-07-09 A bug in which a discipline function applied to a local variable
could cause a shell exception has been fixed. Discipline
functions can only be specified for global variables.
01-06-18 --- Release ksh93l ---
01-06-18 A bug in assigning integers larger than can be represented as
long integers to floating point variables has been fixed.
01-06-18 A bug in the handling of unsigned integers (typeset -ui) has
been fixed.

of the $? variable.
01-06-01 A small memory leak from subshells has been fixed.
01-05-22 A bug in which attributes for variables that did not have
values would be lost after a subshell has been fixed.
01-05-22 The %R format has been added to convert a shell pattern into
an extended regular expression.
01-05-22 The escape sequences \, X, \C[.collating-element.], and
\x{hex} have been added to ASCII-C strings and to printf format
strings.
01-05-20 Patterns of the form {n}(pattern) and {m,n}(pattern) are now
recognized. The first form matches exactly n of pattern whereas,
the second form matches from m to n instances of pattern.
01-05-20 The shell allows *-(pattern), +-(pattern), ?-(pattern),
{m,n}-(pattern}, and @-(pattern) to cause the minimal
match of pattern to be selected whenever possible rather
than the maximal (greedy) match.
01-05-20 The character class [:word:] has been added to patterns.
The word class is the union of [:alnum:] and the character _.
01-05-20 Inside (...) pattern groups, the character is now treated
specially even when in an enclosing character class. The
sequences, \w, \d, \s are equivalent to the character classes
word, digit, and space respectively. The sequences \W, \D,
and \S are their complement sets.
01-05-20 The shell now recognizes pattern groups of the form
~(options:pattern) where options or :pattern can be omitted.
Options use the letters + and - to enable and disable options
respectively. The option letters g (greedy), i (ignore case)
are used to cause maximal matching and to cause case
insensitive matching respectively. If :pattern is also
specified, these options are only in effect while this
pattern is being processed. Otherwise, these options remain
in effect until the end of the pattern group that they are contained
in or until another ~(...) is encountered. These pattern groups
are not counted with respect to group numbering.
01-05-14 When edit completion, expansion, or listing occurs in the
middle of a quoted string, the leading quote is ignored when
performing the completion, expansion, or listing.
01-05-14 A small memory leak from subshells has been fixed.
01-05-10 A bug in which open files were not restored after a subshell
that had used exec to replace a file has been fixed.
01-05-10 Redirection to a null file name now generates an error message.
01-05-09 The shell now rejects some invalid parameter substitutions that
were previously processed in undefined ways.
01-05-09 A bug in which the output of select was not flushed before the
read when input did not come from the terminal has been fixed.
01-05-08 A bug in which job ids would not be freed for interactive shells
when subshells ran built-ins in the background has been fixed.
01-05-08 The FPATH variable now requires an explicit . to cause the
current directory to be treated as a function directory.
01-05-08 A bug in read -n when echo mode was disabled has been fixed.
01-05-07 A bug in which function definitions could be listed as part
of the history has been fixed.
01-04-30 This release uses a new and often much faster pattern matcher than
earlier releases.
01-04-30 An optimizer now eliminates invariant parameter expansions from
for while and until loops.
01-04-30 The variable .sh.match is set after each pattern match (# % or /)
in a variable substitution. The variable .sh.match is an
indexed array with element 0 being the complete match.
The array is only valid until the next subsequent pattern
match or until the value of the variable changes which ever
comes first.
01-04-30 A self generating man page has been added to shcomp. Also,
shcomp now stops compiling when it finds an exit or exec
command and copies the remainder so that it can be used
for standard input.
01-04-30 The shcomp command was modified so that it can work in an
EBCIDIC environment and that binary scripts are portable
across environments.
01-04-30 A bug in the handling of a trailing : in PATH has been fixed.
01-04-30 A bug in which the builtin version of a command would get invoked
even though the full pathname for the command was specified
has been fixed.
01-04-30 A bug in which read would loose the last character when
reading the last line of a file that did not contain a new-line
character has been fixed.
01-04-23 A bug on some systems in which in vi mode the end of file
character and end of line character could be swapped has
been fixed.
01-04-23 A bug on some systems in which invoking a shell script that
did not have execute permission could set the exit value to
127 rather than 126 has been fixed.
01-04-20 A bug in which read -n from a pipe would block if fewer than
n characters was received has been fixed.
01-04-09 A bug in which invalid patterns, for example, ) by itself,
was not treated as a string has been fixed so that if i=')',
then [[ $i == $i ]] is true.
01-04-09 The shell arithmetic now interprets C character constants.
01-04-09 A bug in which a non-zero return from a function defined
with the function reserved word did not trigger the ERR
trap or exit with set -e has been fixed.
01-04-02 A bug on some systems, in which characters above 127 were
not displayed correctly in vi or emacs edit mode has been fixed.
01-04-02 A bug on some systems, introduced in the 'k' point release, in
which the erase character in viraw mode was moving the cursor
to the left without erasing the character has been fixed.
01-04-02 On some systems the wcwith() function was returning a wrong
value for characters and caused characters to be displayed
incorrectly from the shell edit modes. A work around for
this problem has been added.
01-03-26 A bug in which valid scripts could produce syntax errors
when run with locales that considered characters such as "'"
to be space characters has been fixed.
01-03-20 A bug in which an syntax error in an arithmetic expression
entered interactively could cause the shell to go into
an infinite loop outputting the error message has been fixed.
01-03-10 ksh93 accepts -l as a synonym for -L in test on systems for
which /bin/test -l tests for symbolic links.
01-03-10 A bug in parsing scripts in which { and } are used in place of
in and esac in case statements embedded in compound commands
has been fixed. Use of { and } for in and esac is obsolete.
01-03-06 A bug in which an argument of the form foo=bar was not
being passed correctly to a traced function whose name
was foo has been fixed.
01-03-02 Using $(trap -p name) did not print the name of the current
trap setting for trap name.
01-02-26 Exported floating point variables gave incorrect results
when passing them to ksh88. This has been fixed.
01-02-25 A race condition in which a coprocess which completed too quickly
would not allow subsequent coprocesses to start has been fixed.

inadvertently been omitted.
01-02-20 The + was not being displayed during an execution trace
with the += assignment operator.
01-02-19 The error message which occurs when the interpreter name
defined on the #! line does not exist is more informative.
01-02-19 A bug in which $0 would not be set correctly when a
script with #! was invoked by full pathname from the
directory of the script has been fixed.
01-02-19 A shell script did not always pick up tty mode changes
made by external commands such as stty which could
effect the behavior of read.
01-02-19 The -u, -g, and -k unary tests did not give the correct
results when used with negation and this has been fixed.
01-02-05 --- Release ksh93k+ ---
01-02-05 The sequence \<newline> inside $'...' was not incrementing
the line count and this has been fixed.
01-02-05 Modified expansion of "${@-}" so that if no arguments are set
it results in null string rather than nothing.
01-02-02 memory leak problem with local variables in functions fixed.
01-01-25 allow arithmetic expressions with float%int and treat them
as ((int)float)%int rather than as an error.
01-01-19 read -n1 was not working and has been fixed.
01-01-17 ksh now handles the case in which a here document in command
substitution $() is terminated by the trailing ). Previously,
a new-line was needed at the end of the delimiter word.
01-01-02 A bug in which a KEYBD trap would cause a multi-line token
to be processed incorrectly has been fixed.
00-12-10 Arithmetic integer constants can now have L and U suffices.
00-12-10 A bug in the processing of arithmetic expressions with compound
variables when the -n option is on has been fixed.

jobs run in a script has been fixed.
00-11-21 A bug in integer arrays in which the number of elements is
incorrect when the ++ operator is applied to a non-existing
element has been fixed. For example, integer x; ((x[3]++)).
00-11-20 A timing bug in which the shell could reset the terminal
group to the wrong value in the case that the a new process
changes the terminal group during startup has been fixed.
00-10-27 --- Release ksh93k ---
00-10-27 Using tab for completion now works only when applied
after a non-blank character at the end of the current line.

did not work correctly when pattern was '/' or "/" has
been fixed.
00-10-18 The output format for indexed arrays in compound variables
has been modified so that it can be used as input.

implicitly unreference an existing name reference.
00-10-17 A bug the += append operator when a single array element
is appended to a variable that is not an array has been fixed.

has been fixed.
00-08-08 Removed build dependency on iswprint() and iswalph().
00-07-20 In some cases the read builtin would read more than a single
line from a pipe on standard input and therefore leave the seek
position in the wrong location.
00-07-05 If the directory / is on the path, a / will not be inserted
between the directory and the file name during path searching
to avoid searching // for systems that treat this specially.
00-06-26 A bug in which on rare occasions wait could return before all
jobs have completed has been fixed.
00-06-21 A bug in which backspace did not work correctly during the
R replace directive in vi-mode has been fixed.

to printf was not working has been fixed.
99-03-31 --- Release ksh93h ---
99-03-31 The PATH search algorithm has been modified to look
for a file named .fpath in each bin directory and if
found, to search for functions in this directory if
it cannot find the command in that directory.

a stream was repeatedly opened with exec and read from
has been fixed.
98-04-30 --- Release ksh93g ---
98-04-30 The pipefail option has been added. With pipefail
enabled, a pipeline will not complete until all
commands are complete, and the return value will
be that of the last command to fail, or zero if
all complete successfully.
98-04-30 The name-value pair library uses the cdt library rather
than the hash library. This change should be transparent
to applications.
98-04-30 On the U/WIN version for Window 95 and Windows NT,
when a directory beginning with a letter followed by

characters inside a command substitution caused
a syntax error to be reported has been fixed.
98-04-30 A bug in which a decimal constant represented as 10#ddd
where ddd was more than five digits generated a syntax
error has been fixed.
