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.
<P>
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.
<P>
KSH-93 provides the following features, many of which were also inherent
in KSH-88:
<UL type=square>
<LI>
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.
<LI>
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.
<LI>
Extended I/O Capabilities: KSH-93 provides several I/O
capabilities not available in "sh", including the ability to:
<UL type=circle>
<LI>
specify a file descriptor for input and output
<LI>
start up and run co-processes
<LI>
produce a prompt at the terminal before a read
<LI>
easily format and interpret responses to a menu
<LI>
echo lines exactly as output without escape processing
<LI>
format output using printf formats.
<LI>
read and echo lines ending in "\".
</UL>
<LI>
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.
<LI>
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.
<LI>
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.
<LI>
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.
<LI>
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.
<LI>
More pattern matching capabilities: KSH-93 allows you to specify
extended regular expressions for file and string matches.
<LI>
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.
<LI>
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 before each command
so that errors can be localized.
<LI>
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.
<LI>
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.
<LI>
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.
</UL>
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.

the replacement string contained a substring match has been fixed.
12-01-12 +Files that are sourced from profile files are now read and executed
one command at a time so that alias definitions take effect as they
do for profile files.
12-01-12 A bug in which whence -p would find a function if one existed and
there was no command of that name on PATH.
12-01-11 Change b_* prototype (int, char**, void*) => (int, char**, Shbltin_t*).

the same process id as the script has been eliminated.
11-09-21 Added letoctal option that enables the let command to recognize
octal constants starting with 0.
11-09-20 A bug in which ${var.} could cause a core dump has been fixed.

invoked within ((...)) and x y z are long double arguments passed
as name references. y and z are used for functions with two and
three arguments respectively. The value of the function is the value
of the long double .sh.value variable when the function returns.

numerator was a binary operator with the first operand floating
point and the second integer, e.g. (.1**3)/3, has been fixed.

and an edit mode was on, a backspace or erase no longer will
overwrite the prompt.

the version string when enabled. (1) JOBMAX=n limits the number
of concurrent & jobs to n; the n+1 & job will block until a
running background job completes. (2) SIGCHLD traps are queued
so that each completing background job gets its own trap; $! is
set to the job pid and $? is set to the job exit status at the
beginning of the trap. (3) sleep -s added to sleep until the time
expires or until a signal is delivered.

06-10-30 +The redirections <# pattern, and <## pattern have been added.
Both seek forward to the beginning of the next line that contains
the pattern. The <## form copies the skipped portion to standard
output.
06-10-26 +On systems that support stream control transport, the virtual file
name /dev/sctp/host/port can now be used to establish connections.
06-10-26 +The printf modifier # when used with d produces units in thousands
with a single letter suffix added. The modifier # when used with
the i specification provides units of 1024 with a two letter suffix.
06-10-24 The value of $! is now set to the process id of a job put
into the background with the bg command as required by POSIX.
06-10-23 A bug in which the value of $! was affected by a background
job started from a subshell has been fixed.
06-10-23 A bug in ${var:offset:len} in multibyte locales has been fixed.
06-10-15 +The remaining math functions from C99 were added for any system
that supports them.
06-10-13 The klockwork.com software detected a few coding errors that
have been fixed.
06-10-12 A bug when skipping over `...` with ${x:=`...`} when x is set
has been fixed.

pipelines with 3 or more states has been fixed.
06-10-03 A bug in the processing of >(...) with builtins which could
cause the builtin to hang has been fixed.
06-10-03 A bug in the for loop optimizer which causes >(...) process
substitution to be ignored has been fixed.
06-09-17 +The -a option was added to typeset for indexed arrays. This
is only needed when using the ([subscript]=value ...) form.
06-09-06 +The showme option was added. Each simple command not beginning
with a redirection and not occurring with in the while, until, if,
select condition can be preceded by a semi-colon which will
be ignored when showme is off. When showme is on, any command
preceded by a colon will be traced but not executed.
06-08-16 +As a new feature, a leading ~(N) on a pattern has no effect
except when used for file expansion. In this case if not
matches are found, the pattern is replaced by nothing rather
than itself.
06-08-11 A bug in the expansion of ${.sh.match[i]:${#.shmatch[i]}} has
been fixed.
06-08-10 +The read builtin options -n and -N have been modified to treat
the size as characters rather than bytes unless storing into a
binary (typeset -B) variable.
06-07-27 +When the here document operator << is followed directly by a #
rather than a -, the first line of the here-document determines
how much whitespace is removed for each line.
06-07-26 A bug in the C-shell history (enabled with set -H) in which the
history event !$ was not processed has been fixed.
06-07-21 A bug on some systems in which assigning PATH on a command line
would not take effect has been fixed.
06-07-20 Add ksh93 and rksh93 as allowable names for ksh binaries.
06-07-20 Removed the SHOPT_OO compilation option which was only partially
implemented.
06-07-20 The ability to use egrep, grep, and fgrep expressions within
shell patterns has been documented.
06-07-17 A bug with arithmetic command expressions for locales in which
the comma is a thousands separator has been fixed.
06-07-13 +The default HISTSIZE was increased from 128 to 512.
06-07-13 A multibyte problem with locales that use shift codes has been fixed.
06-06-23 A number of bug fixes for command, file, and variable completion
have been mode.
06-06-20 +Floating point division by zero now yields the constant Inf or -Inf
and floating functions with invalid arguments yield NaN.
06-06-20 +The floating point constants Inf and NaN can be used in arithmetic
expressions.
06-06-20 +The functions isinf(), isnan(), tanhl() have been added for
arithmetic expressions.
06-06-13 Internal change to use ordering for variables instead of hashing
to speed up prefix matching.
06-06-13 A window between fork/exec in which a signal could get lost
and cause a program to hang has been eliminated
06-06-13 A bug in edit completion with quoted strings has been fixed.
06-06-07 The restricted options can now be enabled by set as well as on
the command line. Once set, it can not be disabled.
06-06-04 Modified built-in binding so that for systems for which /bin
and /usr/bin are the same, a builtin bound to /bin will get
selected when either /bin or /usr/bin is scanned.
06-06-04 +Added literal-next character processing for emacs/gmacs mode.
This change is not compatible with earlier versions of ksh93
and ksh88 when the stty lnext is control-v. The sequence
escape-control-v will display the shell version.
06-05-31 +Modified emacs and vi mode so that entering a TAB after a partial
TAB completion, generates a listing of possible completions.
After the second TAB, a number followed by a TAB will perform
the completion with the corresponding item.
06-05-19 +Modified arithmetic so that conversions to strings default to
the maximum number of precision digits.
06-05-16 Bug fixes for multibyte locales.
06-05-10 The =~ operator was added to [[...]] and [[ string ~= ERE ]]
is equivalent to [[ string == ~(E)ERE ]].
06-04-25 A bug in the vi edit mode which could cause the shell to core dump
when switching from emacs mode.
06-04-17 A bug in which using LANG or LC_ in assignment lists with builtins
did not restore the localed correctly has been fixed.
06-04-04 A bug in which discipline functions could not be added to variables
whose names started with .sh has been fixed.
06-03-28 +The -s option to typeset was added to modify -i to indicate short
integers.

defined with function name were not passed on the functions
invoked by this function has been fixed.
06-03-28 A bug in which name references defined within a function defined
with function name could not be used with compound variables has
been fixed.
06-03-27 A bug in which read <&p (print >&p) would cause the coprocess input
(output) pipe to close before reading from (after writing to)
it has been fixed.
06-02-28 A bug in which stopping a job created with the hist builtin command
would create a job that could not be restarted has been fixed.
06-01-24 --- Release ksh93r ---
06-01-24 A bug in which running commands with standard output closed would
not work as expected has been fixed.
06-01-23 A bug in which print -u<n> could fail when file descriptor <n> was
open for writing has been fixed.
06-01-19 The ?: arithmetic operator fixed to work when the operation after
the colon was an assignment.
05-12-24 A bug which could lead to a core dump when elements of a compound
variable were array elements, i.e. foo=(bar=(1 2)), has been fixed.
05-12-13 An arithmetic bug in which x+=y+=z was not working has been fixed.
05-12-13 An arithmetic bug in which x||y was returning x when x was non-zero
rather than 1 has been fixed.
05-12-07 +The aliases for integer and float have been changed to use attributes
-li and -lE to handle long long and long double types.
05-12-07 +The histexpand (-H) option has been added which allows C-shell
style history expansions using the history character !.
05-12-07 +The multiline option was added which changes that way the edit
modes handle lines longer than the window width. Instead of
horizontal scrolling, multiple lines on the screen are used.
05-12-05 The whence builtin now returns an absolute pathname when the
command is found in the current directory.
05-11-29 A bug which caused ksh -c '[[ ! ((' to core dump rather than
report a syntax error has been fixed.
05-11-29 A bug when reading fixed length records into typeset -b variables
which caused a zero byte to terminate the value has been fixed.
05-11-22 +The ability to seek to an offset within a file has been added
with the new I/O redirection operators, <# and >#. Currently,
these redirection operators must be followed by ((expr))
but in a future release, it should be able to used to seek forward
to the specified shell pattern. In addition $(n<#) expands to the
current byte offset for file descriptor n.
05-11-22 +The .sh.match array variable is now set after each [[ ... ]]
pattern match. Previously it was only set for substring matches.
05-10-17 A bug in which the library path variable could be prefixed
with a directory when a .path file was not encountered in
the directory of the executable has been fixed.
05-09-15 A for/while loop optimizer bug in which $OPTIND was not
correctly expanded has been fixed.
05-09-05 A bug in which a history command that invoked a history
command could go into an infinite loop has been fixed.
05-08-31 +In the case that IFS contains to adjacent new-lines so that
new-line is not treated as a space delimiter, only a single
new-line is deleted at the end of a command substitution.
05-08-19 +When a tilde substitution expands to the / directory and is
followed by a /, it is replaced by the empty string.
05-08-16 A bug in which n<&m did not synchronize m has been fixed.
05-08-16 A bug in which process substitution ( <() and >() ) was not
working within for and while loops has been fixed.
05-07-24 A bug in which the pattern ~(E)(foo|bar) was treated as a syntax
error has been fixed.
05-07-24 A bug in completion with <n>=, where n was the one of the
previous selection choices has been fixed.
05-07-21 A bug with multibyte input when no edit mode was specified which
caused the input line to shift left/right has been fixed.
05-06-24 A race condition which could cause the exit status to get lost
on some fast systems has been fixed.
05-06-21 A bug in which nested patterns of the form {m,n}(pat) would cause
syntax errors has been fixed.

syntax error for an expansion of the form ${x-$(...)} when
x is set and the command substitution contained certain strings.
05-06-08 +On systems for which echo does not do System V style expansions,
the -e option was added to enable these expansion.
05-06-08 A bug in which ${var op pattern} to not work when inside an
arithmetic expression has been fixed.
05-05-23 +An extension to shell patterns that allows matching of nested
groups while skipping over quoted strings has been added.
05-05-18 A bug in which the line number for errors was not correct for
functions loaded from FPATH has been fixed.
05-04-18 A bug in which the exit status $? is not set when a trap triggered
by the [[...]] command is executed has been fixed.
05-04-08 +Redirection operators can be directly preceded with {varname}
with no intervening space, where varname is a variable name which
allows the shell to select a file descriptor > 10 and store it
into varname.
05-04-08 +SHOPT_CMDLIB_BLTIN=1 now includes <cmdlist.h> generated table.
05-04-07 +[[ -o ?option ]] is true if "option" is a supported option.
05-04-05 A bug in handling file completion with spaces in the names
has been fixed.
05-03-25 +The SIGWINCH signal is caught by default to keeps the LINES and
COLUMNS variables in sync with the actual window size.
05-03-25 +Building ksh with SHOPT_REMOTE=1 causes ksh to set --rc if stdin is
a socket (presumably part of a remote shell invocation.)
05-03-25 +Building ksh with SHOPT_SYSRC=1 causes interactive ksh to source
/etc/ksh.kshrc (if it exists) before sourcing the $ENV file.
05-03-25 +{first..last[..incr][%fmt]} sequences added to brace expansions
when braceexpand is enabled.
05-03-03 A bug where a SIGCHLD interrupt could cause a fifo open to fail has
been fixed.
05-02-25 A bug in which a builtin command run in the background could
keep a file descriptor open which could cause a foreground
process to hang has been fixed.
05-02-24 A bug where builtin library commands (e.g., date and TZ) failed to
detect environment variable changes has been fixed.
05-02-22 +The read builtin and word splitting are now consistent with respect
to IFS -- both treat IFS as field delimiters.
05-02-22 +The read builtin no longer strips off trailing delimiters that
are not space characters when there are fewer variables than fields.
05-02-17 A builtin bug on systems where dlsym(libcmd) returns link-time
bindings has been fixed.
05-02-12 A bug in which the lib_init() function for .paths BUILTIN_LIB
libraries was not called has been fixed.
05-02-06 A bug on some systems in which moving the write end of a co-process
to a numbered file descriptor could cause it to close has been fixed.
05-02-06 A bug in the vi-edit mode in which the character under the cursor
was not deleted in some cases with the d% directive has been fixed.
05-02-06 A bug where external builtin stdout/stderr redirection corrupted
stdout has been fixed.
05-02-04 A bug where times formatting assumed CLK_TCK==60 has been fixed.
05-01-11 --- Release ksh93q ---
05-01-11 A bug in the integral divide by zero check has been fixed.
05-01-11 +The -l option has been added to read /etc/profile and
$HOME/.profile, if they exist, before the first command.
05-01-11 An argument parsing bug that caused `kill -s x -- n' to fail has
been fixed.
05-01-11 +The .paths file, introduced in ksh93m, which can appear in
any directory in PATH, now allows a line of the form 'BUILTIN_LIB=.'
When a command is searched for this directory, and the full path
matches the path of the built-in version of the command (listed
by the 'builtin' command) then the built-in version of the command
is used. When ksh is built with SHOPT_CMDLIB_DIR=1 then all libcmd
functions become builtins with the '/opt/ast/bin/' directory prefix.
05-01-10 A bug in which a nameref to a compound name caused a core dump has
been fixed.
05-01-09 A bug in which some SIGCHLD interrupts (from child processes exiting)
caused a fatal print/echo error diagnostic has been fixed.
04-12-24 A bug in which some SIGCHLD interrupts (from child processes exiting)
corrupted the internal process/job list, sometimes causing the shell
to hang, has been fixed.
04-12-01 A bug in which typeset -Fn truncated less than n digits for large
numbers has been fixed.
04-11-25 A bug in which standard error could be closed after a redirection
to /dev/stderr has been fixed.
04-11-17 A bug in which an expansion of the form ${array[@]:3} could expand
to ${array[0]} when ${array[3]} was not set has been fixed.
04-10-22 +The -E or -orc command line option reads ${ENV-$HOME/.kshrc} file.
04-10-22 +`-o foo' equivalent to `+o nofoo', `-o nobar' equivalent to `+o bar'.
`--foo' equivalent to `-o foo', `--nofoo' equivalent to `+o foo'
04-10-05 +The .paths file, introduced in ksh93m, which can appear in
any directory in PATH, now allows a line of the form
'BUILTIN_LIB=libname'. When a command is searched for this directory,
the shared library named by libname will first be searched for a
built-in version of the command.
04-09-03 <<< here documents now handle quotes in the word token correctly.
04-08-08 +The maximum size for read -n and and read -N was increased from
4095 to 32M.
04-08-04 +printf %q was modified so that if an no operand was supplied, no
no output would be generated rather than a quoted empty string.
04-08-01 +The -n and -N options of the read builtin has been modified
when reading variables with the binary attribute so that the
data is stored directly rather than through assignment.
04-08-01 +The shcomp command has been modified to process alias commands
under some conditions.
04-07-31 +The .sh.match variable added in ksh93l, now works like other
indexed arrays.
04-07-08 A loop optimizer bug which occurs when typeset is used in
a for or while loop inside a function has been fixed.
04-06-24 +The number of subexpressions in a pattern was increased to 64
from the current number of 20.
04-06-17 +The -t option to read was modified to allow seconds to be
specified as any arithmetic expression rather than just
an integral number of seconds, for example even -t 'sin(.5)'
is now valid.
04-06-16 Two small memory leak problems were fixed.
04-06-15 A bug in ${var/pattern/"string"} which occurred when string
contained pattern matching characters has been fixed.
04-05-08 printf $'%d produced an erroneous error message and has
been fixed.
04-05-24 A bug in which an associative array without any elements could
cause a core dump when a script with an associative array with
the same name was declared in a script invoked by name has
been fixed.
04-05-11 A bug in which an exec statement could close the script that
is being processed in a script that is run by name causing
a failure has been fixed.
04-04-28 +If the first character of assignment to an integer variable was 0,
the variable had been treated as unsigned. This behavior was
undocumented and has been removed.
04-04-05 A bug in which the positioning of standard input could be incorrect
after reading from standard input from a subshell has been fixed.
04-03-30 A bug in the for loop optimizer which in rare cases could cause
memory corruption has been fixed.
04-03-29 +The preset alias source='command .' has been added.
04-03-29 A bug introduced in ksh93p on some systems in which invoked by
name with #! on the first line would not get the signals handling
initialized correctly has been fixed.
04-03-29 A bug introduced in ksh93p in which a HUP signal received by
a shell that is a session group leader was not passed down to
its children has been fixed.
04-02-28 --- Release ksh93p ---
04-02-28 +The ability to apply an append discipline to any variable has
been added.
04-02-14 A bug in which the exportall option (set -a) would cause incorrect
results for arrays has been fixed.
04-02-02 A bug in which an exported array would pass more than
the first element to a script invoked by name has been fixed.
04-02-02 A bug on some systems in which name=value pairs preceding a script
invoked by name was not getting passed to the script has been fixed.
04-01-20 A bug in which an unset discipline function could cause a core
dump on some systems has been fixed.
04-01-12 A bug in which a continue or break called outside a loop from
inside a function defined with name() syntax could affect
the invoking function has been fixed.
04-01-08 If a command name begins with ~, only filename completion will be
attempted rather than pathname completion using the builtin editors.
04-01-08 A bug in the vi edit mode in which the wrong repeat count on
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
arguments of size long long on systems that support this.
04-01-06 A bug in which unsetting all elements of an associative array
would cause it to be treated as an indexed array has been fixed.
03-12-15 A bug in which a quoted string ending with an unescaped $ would
delete the ending $ in certain cases has been fixed.
03-12-05 A bug in which the shell could hang when set -x tracing a command
when an invalid multibyte character is encountered has been fixed.
03-12-05 On some systems, if the KEYBD trap is set, then commands that use
the meta key were not processed until return was hit. This
has been fixed.
03-12-05 A problem which occurred when the login shell was not a group
leader that could cause it to fail has been fixed.
03-12-05 A problem in which a shell could core dump after receiving a signal
that should cause it to terminate while it was in the process
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 arithmetic prefix operators ++ 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 computation to avoid being treated
as octal constants when they should not have, has been fixed.
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 implicitly 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.
03-09-03 +The builtin kill command now processes obsolete invocations
such as kill -1 -pid.
03-09-02 The restriction on modifying FPATH in a restricted shell (sh -r)
has been documented.

after () in a Posix function definition to be skipped
when reading from standard input has been fixed.
03-08-01 A bug in which "${foo#pattern}(x)" treated (x) as if it were
part of the pattern has been fixed.
03-08-01 +The command -x option has been modified so that any trailing
arguments that do expand to a single word will be included
on each invocation, so that commands like command -x mv * dir
work as expected.
03-07-20 --- Release ksh93o+ ---
03-07-20 A bug in which could cause memory corruption when a posix
function invoked another one has been fixed.
03-07-15 A bug in which a file descriptor>2 could be closed before
executing a script has been fixed.
03-07-15 A parsing error for <() and >() process substitutions inside
command substitution has been fixed.
03-07-15 A parsing error for patterns of the form {...}(...) when
used inside ${...} has been fixed.
03-07-15 An error in which expanding an indexed array inside a compound
variable could cause a core dump has been fixed.
03-07-15 A bug in which on rare occasions a job completion interrupt
could cause to core dump has been fixed.
03-06-26 A bug in which process substitution embedded within command
substitution would generate a syntax error has been fixed.
03-96-23 A bug in which ${@:offset:len} could core dump when there
were no arguments has been fixed.
03-96-23 A bug in which ${X[@]:offset:len} could core dump when X
was unset has been fixed.
03-06-22 +The -x option was added to the command builtin. If this
option is on, and the number of arguments would exceed ARG_MAX,
the command will be invoked multiple times with a subset of
the arguments. For example, with alias grep='command -x grep,
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.
03-06-06 A bug in which the shell could core dump when a script was
run from its directory, and the script name a symlink to a file
beginning with .., has been fixed.
03-06-05 A bug in which the shell could core dump when a child process
that it is unaware of terminates while it is calling malloc()
has been fixed.
03-06-02 +An option named globstar (set -G) has been added. When enabled,
during pathname expansion, any component that consists only of ** is
matches all files and any number of directory levels.
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 output 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.
03-05-19 A job control bug which would cause the shell to exit because
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
with .sh. has been fixed.
03-05-13 A bug in the expansion of $var for compound variables in which
some elements would not be output when the name was a prefix
of another name in the compound variable has been fixed.
03-05-08 The last item in the ksh93o release on 03-01-02 has been
altered slightly 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 containing 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.

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.

02-11-14 +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.

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.

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.

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.

a / has been fixed.
02-09-14 A bug in the parser for strings of the form name$((expr))=value
has been fixed.

02-09-09 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 interpreted as an array assignment rather than a
compound variable assignment has been fixed.

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.
02-08-11 A bug in arithmetic rounding in which a value input as a decimal
string would output as a rounded version of the string has
been fixed.
02-08-11 A bug in which the last character could be deleted from shell
traces and from whence when called from a multibyte locale
has been fixed.
02-08-01 A bug which could cause a core dump to occur when a shell script
is executed while a coprocess is running that has closed the
output pipe has been fixed.

corrupt memory for long command lines has been fixed.
02-06-17 --- Release ksh93n- ---
02-06-17 A bug in which user defined macros could cause a core dump in
with MULTIBYTE mode has been fixed.
02-06-17 A bug in which printf format specifiers of the form %2$s were causing
a core dump has been fixed.
02-06-17 A bug in which setting stty to noecho mode did not prevent the
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.
02-06-17 A bug in which the shell could core dump if getopts was called
when the OPTIND variable contained a negative value has been fixed.
02-06-10 +The edit mode prompt has been modified to handle escape sequences.
02-06-10 A bug which occurred for interactive shells in which the builtin

size was larger than PIPE_BUF has been fixed.
02-06-10 A bug in which the trap on ERR was not being processed when
set inside a function has been fixed.

has been fixed.
02-05-23 A bug with unary + introduced in ksh93k has been fixed.
02-05-07 A bug in substitutions of the form ${var/pattern/string} in which
a backslash was inserted in the replacement string when it contained
a special pattern character 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.
02-03-26 --- Release ksh93m+ ---
02-03-26 A bug in which was not handled correctly when used in file
expansion has been fixed.
02-02-18 A bug in which lines beginning with a # were deleted from here
documents when the here-document delimiter was followed by
a comment has been fixed.
02-12-06 An optimization bug in which ${!x[@]) was treated as invariant in
a for loop has been fixed.
02-02-06 A bug in which the ERR trap is not cleared for a script invoked
by name from within a function has been fixed.
02-01-08 A bug in which a shell script executed from within a subshell
could cause this script to have an invalid pointer leading
to a memory fault has been fixed.
02-01-07 +Added here documents of the form <<< word (as per zsh) which
is equivalent to << delimordelim.
02-01-07 A bug in which the first word of a compound assignment,
x=(word ...), was treated as a reserved word has been fixed.
02-01-07 A bug in the handling of when noglob was enabled and a
substitution of the form ${word op pattern} occurred in the
same word has been fixed.
02-01-07 +A compilation option, CMDLIB_BLTIN in the file OPTION, has
been added. When this options is set, all commands implemented
in libcmd become shell builtin commands by default.
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

the original trap wasn't executed.
01-11-26 +The value for 0 is now preceded by the base number when
the base was not 10.
01-11-26 +The default has compilation mode has been changes so that
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
that do not have any attributes that are set.
01-10-16 A bug introduced in ksh93l in which assignments specified with
the exec built-in were not being expanded properly has been

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.

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.

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 \, <JOIN>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.
01-02-25 The 'g' format specifier is now handled by printf. It had
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.
00-12-08 A bug in M-f and M-b from emacs mode has been fixed. This
bug only occurs when ksh93 is compiled without MULTIBYTE enabled.
00-11-29 A bug in which jobs -p would yield 0 for background
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.
In other case a tab is inserted.
00-10-27 A bug in the emacs edit mode for ^X^E has been fixed.
The ^X^E sequence is supposed to invoke the full editor
on the current command.
00-10-18 A bug in which expansions of the form ${var//pattern/string}
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.
00-10-18 Assignments with name references (typeset -n) will now
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.
00-10-16 A bug in which the SIGCONT signal was being sent to
each process will kill -0 or kill -n 0 has been fixed.
00-10-12 +The arithmetic evaluation portion has been rewritten to
perform a number of optimizations.
00-10-10 A bug in which name prefix matching ${!name.*} was not
checking name to see if it was a name reference has been fixed.
00-09-26 A bug in the multibyte version in which the width of for
non-printing characters was not correct has been fixed.
00-09-12 +Made changes to get multibyte editing work on UWIN for windows
00-09-12 A bug in which multibyte characters would be displayed incorrectly
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.
00-06-12 +Added variable name completion/expansion/listing to the set of
completions. Variable name completions begin with $ or "$ followed
by a letter.
00-05-09 --- Release ksh93j ---
00-05-09 Modified command substitution to avoid using /tmp files when
