1N/A now outputs an error message and returns value 126.
1N/A10-06-23 Floating point functions that happened to return integer values
1N/A were being treated as if the function returned integers so that
1N/A integer division could be used instead of floating point division.
1N/A10-06-22 Fixed a bug in earlier ksh93u in which an arithmetic assignment to a
1N/A variable in the global scope would instead create a local variable if

1N/A no argument), when foo[0] is not empty has been fixed.
1N/A06-11-16 The discipline functions have been modified to allow each subscript
1N/A to act independently. Currently the discipline function will not
1N/A be called when called from a discipline function of the same variable.

1N/A by
/bin/sh rather than the current shell on some systems has
1N/A03-09-12 +To improve conformance with ksh88, leading zeros will be ignored
1N/A when getting the numerical value of a string variable so that
1N/A they will not be treated as octal constants.
1N/A03-09-03 +The builtin kill command now processes obsolete invocations

1N/A was found in. The variable
.sh.fun names the current function
1N/A of the current subshell or command substitution.
1N/A03-03-03 +When the DEBUG trap is executed, the current command line after
1N/A is also now triggered before each iteration of a for, select,
1N/A and case command and before each assignment and redirection.
1N/A03-02-28 +Function definitions are no longer stored in the history file so
1N/A that set -o nolog no longer has any meaning.
1N/A03-02-28 +All function definitions can be displayed with typeset -f not
1N/A just those stored in the history file. In addition, typeset +f
1N/A displays the function name followed by a comment containing the
1N/A line number and the path name for the file that defined this function.
1N/A03-02-28 A bug in which the value of $LINENO was not correct when executing
1N/A command contained inside mult-line command substitutions has been
1N/A03-02-19 +Since some existing ksh88 scripts use the undocumented and

1N/A03-01-02 For backward compatibility with ksh88, arithmetic expansion
1N/A with ((...)) and let has been modified so that if x is a zero-filled
1N/A variable, $x will not be treated as an octal constant.

1N/A command substitution has been fixed.
1N/A01-08-09 Another bug in the optimization of for loops in ksh93l caused
1N/A errors in recursive functions using local variables that
1N/A contained for loops has been fixed.
1N/A01-07-27 A bug in which IFS would be unset after a command substitution
1N/A inside a here document has been fixed.
1N/A01-07-26 To conform to the POSIX standard, if you invoked ksh name,
1N/A and name does not contain a /, it will first try to run
1N/A one in the current directory whether it is executable or not
1N/A before doing a path search for an executable script. Earlier
1N/A versions first checked for an executable script using the
1N/A01-07-23 A bug in which unset -f invoked in a subshell could unset a
1N/A function defined in the parent has been fixed.
1N/A01-07-16 A bug in the optimization of for loops in ksh93l caused
1N/A name references to be treated as invariants has been fixed.
1N/A01-07-09 A bug in which a discipline function applied to a local variable
1N/A could cause a shell exception has been fixed. Discipline
1N/A functions can only be specified for global variables.
1N/A01-06-18 --- Release ksh93l ---
1N/A01-06-18 A bug in assigning integers larger than can be represented as
1N/A long integers to floating point variables has been fixed.
1N/A01-06-18 A bug in the handling of unsigned integers (typeset -ui) has
1N/A01-06-04 The evaluation of the PS1 prompt no longer effects the value
1N/A01-06-01 A small memory leak from subshells has been fixed.
1N/A01-05-22 A bug in which attributes for variables that did not have
1N/A values would be lost after a subshell has been fixed.
1N/A01-05-22 +The %R format has been added to convert a shell pattern into
1N/A an extended regular expression.
1N/A01-05-22 +The escape sequences \e, \cX, \C[.collating-element.], and
1N/A \x{hex} have been added to ASCII-C strings and to printf format
1N/A01-05-20 +Patterns of the form {n}(pattern) and {m,n}(pattern) are now
1N/A recognized. The first form matches exactly n of pattern whereas,
1N/A the second form matches from m to n instances of pattern.
1N/A01-05-20 +The shell allows *-(pattern), +-(pattern), ?-(pattern),
1N/A {m,n}-(pattern}, and @-(pattern) to cause the minimal
1N/A match of pattern to be selected whenever possible rather
1N/A than the maximal (greedy) match.
1N/A01-05-20 +The character class [:word:] has been added to patterns.
1N/A The word class is the union of [:alnum:] and the character _.
1N/A01-05-20 +Inside (...) pattern groups, the \ character is now treated
1N/A specially even when in an enclosing character class. The
1N/A sequences, \w, \d, \s are equivalent to the character classes
1N/A word, digit, and space respectively. The sequences \W, \D,
1N/A and \S are their complement sets.
1N/A01-05-20 +The shell now recognizes pattern groups of the form
1N/A ~(options:pattern) where options or :pattern can be omitted.
1N/A Options use the letters + and - to enable and disable options
1N/A respectively. The option letters g (greedy), i (ignore case)
1N/A are used to cause maximal matching and to cause case
1N/A insensitive matching respectively. If :pattern is also
1N/A specified, these options are only in effect while this
1N/A pattern is being processed. Otherwise, these options remain
1N/A in effect until the end of the pattern group that they are contained
1N/A in or until another ~(...) is encountered. These pattern groups
1N/A are not counted with respect to group numbering.
1N/A01-05-14 When edit completion, expansion, or listing occurs in the
1N/A middle of a quoted string, the leading quote is ignored when
1N/A performing the completion, expansion, or listing.
1N/A01-05-14 A small memory leak from subshells has been fixed.
1N/A01-05-10 A bug in which open files were not restored after a subshell
1N/A that had used exec to replace a file has been fixed.
1N/A01-05-10 +Redirection to a null file name now generates an error message.
1N/A01-05-09 The shell now rejects some invalid parameter substitutions that
1N/A were previously processed in undefined ways.
1N/A01-05-09 A bug in which the output of select was not flushed before the
1N/A read when input did not come from the terminal has been fixed.
1N/A01-05-08 A bug in which job ids would not be freed for interactive shells
1N/A when subshells ran built-ins in the background has been fixed.
1N/A01-05-08 +The FPATH variable now requires an explicit . to cause the
1N/A current directory to be treated as a function directory.
1N/A01-05-08 A bug in read -n when echo mode was disabled has been fixed.
1N/A01-05-07 A bug in which function definitions could be listed as part
1N/A of the history has been fixed.
1N/A01-04-30 +This release uses a new and often much faster pattern matcher than
1N/A01-04-30 +An optimizer now eliminates invariant parameter expansions from
1N/A for while and until loops.
1N/A01-04-30 +The variable
.sh.match is set after each pattern match (# % or /)
1N/A indexed array with element 0 being the complete match.
1N/A The array is only valid until the next subsequent pattern
1N/A match or until the value of the variable changes which ever
1N/A01-04-30 +A self generating man page has been added to shcomp. Also,
1N/A shcomp now stops compiling when it finds an exit or exec
1N/A command and copies the remainder so that it can be used
1N/A01-04-30 +The shcomp command was modified so that it can work in an
1N/A EBCIDIC environment and that binary scripts are portable
1N/A across environments.
1N/A01-04-30 A bug in the handling of a trailing : in PATH has been fixed.
1N/A01-04-30 A bug in which the builtin version of a command would get invoked
1N/A even though the full pathname for the command was specified
1N/A01-04-30 A bug in which read would lose the last character when
1N/A reading the last line of a file that did not contain a new-line
1N/A character has been fixed.
1N/A01-04-23 A bug on some systems in which in vi mode the end of file
1N/A character and end of line character could be swapped has
1N/A01-04-23 A bug on some systems in which invoking a shell script that
1N/A did not have execute permission could set the exit value to
1N/A 127 rather than 126 has been fixed.
1N/A01-04-20 A bug in which read -n from a pipe would block if fewer than
1N/A n characters was received has been fixed.
1N/A01-04-09 A bug in which invalid patterns, for example, ) by itself,
1N/A was not treated as a string has been fixed so that if i=')',
1N/A then [[ $i == $i ]] is true.
1N/A01-04-09 +The shell arithmetic now interprets C character constants.
1N/A01-04-09 A bug in which a non-zero return from a function defined
1N/A with the function reserved word did not trigger the ERR
1N/A trap or exit with set -e has been fixed.
1N/A01-04-02 A bug on some systems, in which characters above 127 were
1N/A not displayed correctly in vi or emacs edit mode has been fixed.
1N/A01-04-02 A bug on some systems, introduced in the 'k' point release, in
1N/A which the erase character in viraw mode was moving the cursor
1N/A to the left without erasing the character has been fixed.
1N/A01-04-02 On some systems the wcwith() function was returning a wrong
1N/A value for characters and caused characters to be displayed
1N/A incorrectly from the shell edit modes. A work around for
1N/A this problem has been added.
1N/A01-03-26 A bug in which valid scripts could produce syntax errors
1N/A when run with locales that considered characters such as "'"
1N/A to be space characters has been fixed.
1N/A01-03-20 A bug in which an syntax error in an arithmetic expression
1N/A entered interactively could cause the shell to go into
1N/A an infinite loop outputting the error message has been fixed.
1N/A01-03-10 +ksh93 accepts -l as a synonym for -L in test on systems for
1N/A01-03-10 A bug in parsing scripts in which { and } are used in place of
1N/A in and esac in case statements embedded in compound commands
1N/A has been fixed. Use of { and } for in and esac is obsolete.
1N/A01-03-06 A bug in which an argument of the form foo=bar was not
1N/A being passed correctly to a traced function whose name
1N/A was foo has been fixed.
1N/A01-03-02 Using $(trap -p name) did not print the name of the current
1N/A trap setting for trap name.
1N/A01-02-26 Exported floating point variables gave incorrect results
1N/A when passing them to ksh88. This has been fixed.
1N/A01-02-25 A race condition in which a coprocess which completed too quickly
1N/A would not allow subsequent coprocesses to start has been fixed.
1N/A01-02-25 The 'g' format specifier is now handled by printf. It had
1N/A inadvertently been omitted.
1N/A01-02-20 The + was not being displayed during an execution trace
1N/A with the += assignment operator.
1N/A01-02-19 The error message which occurs when the interpreter name
1N/A defined on the #! line does not exist is more informative.
1N/A01-02-19 A bug in which $0 would not be set correctly when a
1N/A script with #! was invoked by full pathname from the
1N/A directory of the script has been fixed.
1N/A01-02-19 A shell script did not always pick up tty mode changes
1N/A made by external commands such as stty which could
1N/A effect the behavior of read.
1N/A01-02-19 The -u, -g, and -k unary tests did not give the correct
1N/A results when used with negation and this has been fixed.
1N/A01-02-05 --- Release ksh93k+ ---
1N/A01-02-05 The sequence \<newline> inside $'...' was not incrementing
1N/A the line count and this has been fixed.
1N/A01-02-05 +Modified expansion of "${@-}" so that if no arguments are set
1N/A it results in null string rather than nothing.
1N/A01-02-02 memory leak problem with local variables in functions fixed.
1N/A01-01-25 +allow arithmetic expressions with float%int and treat them
1N/A as ((int)float)%int rather than as an error.
1N/A01-01-19 read -n1 was not working and has been fixed.
1N/A01-01-17 +ksh now handles the case in which a here document in command
1N/A substitution $() is terminated by the trailing ). Previously,
1N/A a new-line was needed at the end of the delimiter word.
1N/A01-01-02 A bug in which a KEYBD trap would cause a multi-line token
1N/A to be processed incorrectly has been fixed.
1N/A00-12-10 +Arithmetic integer constants can now have L and U suffices.
1N/A00-12-10 A bug in the processing of arithmetic expressions with compound
1N/A variables when the -n option is on has been fixed.
1N/A00-12-08 A bug in M-f and M-b from emacs mode has been fixed. This
1N/A bug only occurs when ksh93 is compiled without MULTIBYTE enabled.
1N/A00-11-29 A bug in which jobs -p would yield 0 for background
1N/A jobs run in a script has been fixed.
1N/A00-11-21 A bug in integer arrays in which the number of elements is
1N/A incorrect when the ++ operator is applied to a non-existing
1N/A element has been fixed. For example, integer x; ((x[3]++)).
1N/A00-11-20 A timing bug in which the shell could reset the terminal
1N/A group to the wrong value in the case that the a new process
1N/A changes the terminal group during startup has been fixed.
1N/A00-10-27 --- Release ksh93k ---
1N/A00-10-27 Using tab for completion now works only when applied
1N/A after a non-blank character at the end of the current line.
1N/A In other case a tab is inserted.
1N/A00-10-27 A bug in the emacs edit mode for ^X^E has been fixed.
1N/A The ^X^E sequence is supposed to invoke the full editor
1N/A on the current command.
1N/A did not work correctly when pattern was '/' or "/" has
1N/A00-10-18 +The output format for indexed arrays in compound variables
1N/A has been modified so that it can be used as input.

1N/A00-09-12 A bug in which multibyte characters would be displayed incorrectly
1N/A00-08-08 Removed build dependency on iswprint() and iswalph().
1N/A00-07-20 In some cases the read builtin would read more than a single
1N/A line from a pipe on standard input and therefore leave the seek
1N/A position in the wrong location.
1N/A00-07-05 +If the directory / is on the path, a / will not be inserted
1N/A between the directory and the file name during path searching
1N/A to avoid searching // for systems that treat this specially.
1N/A00-06-26 A bug in which on rare occasions wait could return before all
1N/A jobs have completed has been fixed.
1N/A00-06-21 A bug in which backspace did not work correctly during the

1N/A run on read-only file systems.
1N/A00-04-17 +Modified printf to handle '%
..Xc' and '%
..Xs' options where X

1N/A00-03-30 +Code was modified in several places to support automatic
1N/A generation of C locale dictionaries.
1N/A00-03-28 A bug in which the set and trap commands invoked with --name
1N/A type arguments would terminate the invoking script has
1N/A00-03-27 A bug in which the library path variable was not updated
1N/A correctly on some systems as described in the 'g' point
1N/A release has been fixed.
1N/A00-03-07 printf now returns a non-zero exit status when one of
1N/A its arguments cannot be converted to the given type.
1N/A00-03-05 The return value and error message for a command that
1N/A was found on the path but was not executable was set
1N/A00-03-05 A prototype for ioctl() was removed from the vi edit mode.
1N/A00-01-28 --- Release ksh93i ---
1N/A00-01-28 +Most of the built-in commands and ksh itself are now
1N/A self documenting. Running command --man will produce
1N/A screen output. Running command --html produces the
1N/A man page in html format.
1N/A00-01-28 +The getopts builtin can process command description
1N/A strings to produce man pages.
1N/A00-01-28 A bug in which a script could terminate when getopts
1N/A encountered an error when invoked inside a function
1N/A00-01-28 When a symbolic link was specified as the name of
1N/A the script to invoke by name, the value of $0 was
1N/A set to the real file name rather than the link name
1N/A in some cases and this has been fixed.
1N/A00-01-28 A bug in which the precision given as an argument
1N/A to printf was not working has been fixed.
1N/A99-03-31 --- Release ksh93h ---
1N/A99-03-31 +The PATH search algorithm has been modified to look
1N/A for a file named .fpath in each bin directory and if
1N/A found, to search for functions in this directory if
1N/A it cannot find the command in that directory.
1N/A99-03-31 +When performing pathname expansion, the shell checks
1N/A to see whether each directory it reads is case sensitive
1N/A or not, and performs the matching accordingly.
1N/A99-03-31 +The emacs and vi modes now handle arrow keys when
1N/A they use standard ANSI escape sequences.
1N/A99-03-31 +The TAB key can be used for completion in emacs and viraw mode.
1N/A for the MULTIBYTE option was fixed in release ksh93h.
1N/A99-03-31 A bug in shcomp for compilation of unary operators with [[...]]

1N/A <ESC>[#~ were not being handled as a unit has been fixed.
1N/A99-03-31 A bug in which ksh would consider expressions like [[ (a) ]]
1N/A as syntax errors has been fixed.

1N/A was not reported as a syntax error.
1N/A99-03-31 A bug in which ksh could run out of file descriptors when
1N/A a stream was repeatedly opened with exec and read from
1N/A98-04-30 --- Release ksh93g ---
1N/A98-04-30 +The pipefail option has been added. With pipefail
1N/A enabled, a pipeline will not complete until all
1N/A commands are complete, and the return value will
1N/A be that of the last command to fail, or zero if
1N/A all complete successfully.
1N/A98-04-30 +The name-value pair library uses the cdt library rather
1N/A than the hash library. This change should be transparent
1N/A98-04-30 +On the
U/WIN version for Window 95 and Windows NT,
1N/A when a directory beginning with a letter followed by
1N/A a colon is given to cd, it is assumed to be an absolute
1N/A98-04-30 +When an executable is found on a given path,
1N/A the appropriate library path variable is prepended
1N/A with a corresponding library directory.

1N/A98-04-30 A bug in line continuation in here-documents has been
1N/A98-04-30 The default base when not specified with typeset -i is
1N/A 10 in accordance with the documentation. Previously,
1N/A the value was determined by the first assignment.
1N/A98-04-30 A parsing bug in which a # preceded alphanumeric
1N/A characters inside a command substitution caused
1N/A a syntax error to be reported has been fixed.
1N/A98-04-30 A bug in which a decimal constant represented as 10#ddd
1N/A where ddd was more than five digits generated a syntax
1N/A error has been fixed.
1N/A98-04-30 A bug in here document expansion in which ${...} expansions
1N/A were split across buffer boundaries has been fixed.
1N/A98-04-30 +The sh_fun() function now takes third argument which
1N/A is an argument list for the invoked discipline function
1N/A98-04-30 +A callback function can be installed which will give
1N/A notification of file duplications and file closes.
1N/A98-04-30 When ksh is compiled on systems that do not use fork()
1N/A current option settings where not propagated to sub-shells.
1N/A97-06-30 --- Release ksh93f ---
1N/A97-06-30 +Hostnames in addition to host addresses can be given in
1N/A97-06-30 File name completion and expansion now quotes special
1N/A characters in file names from both emacs and vi edit modes.
1N/A97-06-30 An empty for list behave like a for list with null expansions.
1N/A It produces a warning message with sh -n.
1N/A97-06-30 +The code has been modified to work with EBCDIC as well as ASCII.
1N/A97-06-30 A bug which would cause the secondary prompt to be
1N/A displayed when a user entered a literal carriage
1N/A return has been fixed.

1N/A prevent variable substitution to occur after $(...) command
1N/A substitution for long here documents has been fixed.
1N/A97-06-30 A bug caused by a race condition that could cause SIGTERM
1N/A to be ignored by a child process has been fixed.

1N/A after killing a running coprocess has been fixed.
1N/A97-06-30 ulimit foobar, where foobar is not an arithmetic
1N/A expression, now gives an error message as it did with ksh88
1N/A instead of setting the file size limit to 0.
1N/A97-06-30 A bug which could cause an interactive shell to terminate when
1N/A the last process of a pipeline was a POSIX function was fixed.
1N/A97-06-30 A bug which could cause command substitution of a shell script
1N/A to core dump has been fixed.
1N/A97-06-30 A security hole was fixed in suid_exec.
1N/A97-06-30 Arithmetic functions such as pow() that take more than
1N/A one argument, did not work if arguments other than the
