The AT&T Software Technology ast-ksh package from AT&T Research contains ksh and support libraries. This is the minimal set of components needed to build ksh. This package is a superset of the following package: ksh; you won't need this if you download ast-ksh. Source Package Installation Instructions: (1) Do not install packages as root/super-user. Although some components may have setuid executables, few must be owned by root. These are best changed manually when the security implications are understood. (2) Choose a package root directory and cd to it. This will be a local work area for all packages. (3) These instructions bypass the click to download package links on the download site. If you already clicked, or if your system does not have curl(1), hurl(1), lynx(1) or wget(1) then use the alternate instructions for (3),(4),(5) in plan B below. Plan B installs the hurl(1) script which works with ksh and modern bash. The top level URL is: URL=http://www.research.att.com/sw/download (4) If the bin/package script does not exist then run: test -d bin || mkdir bin url=$URL/package (wget -O bin/package $url||curl $url||hurl $url) > bin/package chmod +x bin/package (5) Determine the list of package names you want from the download site, then use the package(1) command to do the actual download: bin/package authorize "NAME" password "PASSWORD" \ setup source $URL PACKAGE ... (Refer to the AUTHORIZATION paragraph on the main download page for NAME/PASSWORD details.) This downloads the closure of the latest source package(s); covered and up-to-date packages are not downloaded again unless package force ... is specified. Package content is verified using md5sum. If the package root will contain only one architecture then you can install in bin and lib instead of arch/HOSTTYPE/bin and arch/HOSTTYPE/lib by running this instead: bin/package authorize "NAME" password "PASSWORD" \ flat setup source $URL PACKAGE ... To update the same packages from the same URL run: bin/package setup source (6) Build and install; all generated files are placed under arch/HOSTTYPE ($INSTALLROOT), where HOSTTYPE is the output of bin/package (with no arguments.) name=value arguments are supported; CC and debug=1 (compile with -g instead of -O) are likely candidates. The output is written to the terminal and captured in $INSTALLROOT/lib/package/gen/make.out: bin/package make (7) List make results and interesting errors: bin/package results Run the regression tests: bin/package test List test results and errors: bin/package results test (8) The generated binaries are position independent, i.e., they do not contain hard-coded paths. However, commands with related files, like file(1) and nmake(1), require the path of the bin directory to be exported in PATH. (9) You can run the binaries directly from the package root, or you can install them in a public root after you are satisfied with the make and test actions (requires the AT&T nmake(1) command): bin/package flat install DIRECTORY PACKAGE This will install in DIRECTORY/bin and DIRECTORY/lib. If you want to preserve the arch/HOSTTYPE hierarchy under DIRECTORY then omit the flat argument. If you don't have nmake(1) then the following will do a flat install: cd $INSTALLROOT cp -p -r bin lib include DIRECTORY (10) To summarize, after the first time the download, build, and test cycle for the latest source release is: bin/package setup source bin/package make bin/package test Source Package Installation Instructions -- Plan B: (3) Create the subdirectory lib/package/tgz and download all package archives into that directory. (4) If the bin/package script does not exist then manually read the INIT source package: gunzip < lib/package/tgz/INIT.YYYY-MM-DD.tgz | tar xvf - Note that some browsers automatically unzip downloaded without warning. If the gunzip fails try: tar xvf - lib/package/tgz/INIT.YYYY-MM-DD.tgz If your system does not have tar(1) or gunzip(1) then download the ratz source package, compile it, and manually read the INIT source package: mkdir bin cp lib/package/tgz/ratz.YYYY-MM-DD.c lib/package/tgz/ratz.c cc -o bin/ratz lib/package/tgz/ratz.c bin/ratz -lm < lib/package/tgz/INIT.YYYY-MM-DD.tgz (5) Read all unread package archive(s): bin/package read Both source and binary packages will be read by this step. All recorded changes follow. :::::::: ksh93 :::::::: 11-02-08 --- Release ksh93u --- 11-02-08 A bug in which opening standard output after it has been closed with exec 1>&- doesn't work has been fixed. 11-02-07 A bug on some systems for which a command subtitution could hang has been fixed. 11-01-28 A bug in file name completion for files containing both multibyte characters shell special characters has been fixed. 11-01-18 The .sh.match variable now shows elements that do not match as as not set rather than an empty string. 11-01-18 A bug with typeset -m of an array into an element of an indexed array has been fixed. 11-01-13 A bug in handling of arrays of compound variables inside ((...)) which reported a syntax error been fixed. 11-01-10 A bug in arithmetic assignment operators of the form op= for array variables when the same array was referenced on the left and the right hand side with different indices has been fixed. 11-01-10 A bug in which the output of time was lost when { time...;} 2>&1 occured inside command substition has been fixed. 11-01-07 [[ -v sh.match[i] ]] was returning false when sh.match[i] was set. 11-01-05 Added and modified warning messages with sh -n. 11-01-02 Fixed bugs with typeset -l/-u/-M and arrays. 10-12-28 Fixed a bug with typeset -l/-u/-M values in arithmetric expressions. 10-12-26 Fixed a time parsing bug in sleep and localeconv() initialization. 10-12-23 Prevented the shell from generating a core dump when it sends itself a termination signal because the last command terminated with that signal. This prevents a core dump to be overwritten by the shell. 10-12-22 A bug in the expansion of ${A[@]} ${B[@]}, introduced in 10-12-01 when A="" B=B has been fixed. 10-12-21 +Use MS_3D in b_vpath() for setting win32 WoW mount defaults. 10-12-17 A bug in the expansion of ${var:i:j} which caused a core dump when i > ${#var} has been fixed. 10-12-16 +sleep now treats . as decimal point even in locales that use comma. 10-12-16 +typeset -M mapname was added to generalize on toupper and tolowwer mapping as provided with wctrans(). 10-12-10 A bug in which typeset -l displayed namespaces as well as lower case variables has been fixed. 10-12-06 A bug in which a pipeline could terminate prematurely for a pipeline whose right hand side is a builtin, and whose left hand side ends in a simple command that has standard output redirected has been fixed. 10-12-06 A bug in hexfloat assignments when the right hand side is a string variable starting with 0x has been fixed. 10-12-01 A bug in the expansion of ${$1+"$@"} which causes the last positional parameter to disappear when it is empty has been fixed. 10-12-01 A number of changes were made to reduce the startup time. 10-11-29 When wait is interrupted by a signal that is caught, it now exits with a non-zero exit status. 10-11-29 When a variable is used directly in an arithmetic expression, leading zeros no longer cause the value to be treated as an octal constant. This was true in previous versions for justified variables. 10-11-29 An incorrect warning message was eliminated with the -n option for arithmetic expressions with associative arrays. 10-11-29 Some changes were made to slightly reduces startup time. 10-11-24 A bug in which a name reference is make to arr[0] when arr is not an array has been fixed. 10-11-23 If a type definition is made without a compound variable assignment it produces an error message and no longer shows up as a defined type. 10-11-22 The handling of \ inside [...] for for shell and ~(E) patterns has been fixed. 10-11-22 A patch was made to pfsh to handle an error case. 10-11-22 +Modified types defined in namespace so that they do not clash with types in other namespaces.

It allows fixed sized indexed arrays be to defined using "typeset array[dim1][dim2]...[dimn]". Fixed sized arrays are used the same way indexed arrays are. Currently, only fixed arrays of fixed objects (float, int, and justifies objects) are supported. 10-09-22 A bug which could cause an excpetion when a function with static variables was redefined has been fixed. 10-09-21 A bug in the processing of (command&) which created a job in the parent process has been fixed. 10-09-21 A for loop optimization bug with arithmetic expression evaluation has been fixed. 10-09-21 A bug in which a recursive function containing a pipeline could lead to an exception fixed after 8 levels of recursion has been fixed. 10-09-18 A bug in which the count of elements in an array was wrong leading to an excpetion has been fixed. 10-09-13 A bug which occured when both xtrace and showme options where specified in which the xtrace option disabled showme has been fixed. 10-09-13 A bug in which creating a reference to an array variable with any elements could cause subsequent array elements to be treated as compound variables has been fixed. 10-09-09 A bug which caused ((c.ar[x][y])) to be treated as a syntax error has been fixed. 10-09-08 A bug in the processing of references to multidimensional arrays in arithmetic expressions has been fixed. 10-09-08 A bug in the handling of multi-dimensional arrays which caused the number of elements in each dimension to be incorrect has been fixed. 10-09-07 The change for messages on 10-08-09 did not handle message in assignments and this has been fixed. 10-09-07 A bug in the indentation of compound variables in arrays when output with print -v has been fixed. 10-09-07 A rare bug with indexed arrays when assigned a null string that could cause a core dump has been fixed. 10-09-03 A number of changes were made for jobs pools. 10-08-31 typeset -p was modified to output name references after other variables so that the output could be used as input. 10-08-31 A bug with typeset -p in which variables with attributes but without attributes were not displayed correctly has been fixed. 10-08-27 +When running a subshell, the current pool is unset. 10-08-27 A bug in which jobs started from within for or while lists in interactive shells could generate completion messages has been fixed. 10-08-25 Fixed a couple of bugs related to job pools. 10-08-24 +[[ -e /dev/xxx/ ]] can be used to check whether special files of those names are handled by the shell. 10-08-24 A bug in the running of a compiled dot script in which only the first command was executed has been fixed. 10-08-23 A bug which sometimes caused a core dump with a confgire script has been fixed. 10-08-20 A bug in command substitution which caused a configure script to hang has been fixed. 10-08-19 Eliminated unnecessary ; from output of compound variable with typeset -p. 10-08-17 Fixed a bug in command substitution in which under certain circumstances a file whose size is a power of 2 plus one, and the last character was not a new-line, could cause memory corruption. 10-08-13 +Added static discipline functions to type similar to C++ static class functions. 10-08-11 A bug in time when applied to a pipeline in which the shell did not wait for all elements of the pipeline to complete has been fixed. 10-08-11 Restored sh_fmtq() quoting to not quote NAME= in NAME=VALUE. 10-08-09 +Modified the expansion of message strings, $"...", so that they are expanded each time they are referenced rather than expanding them when the script is compiled or read in. 10-08-06 +The process id for jobs in job pools is now of the form poolname.n where n is the jobid in that pool. Commands that accept job names or numbers now understand names in this format. 10-08-05 A bug in which an assignment from within an arithmetic expression inside a function would create a local variable has been fixed. 10-08-04 A bug in the expanding of variables whose names contain multibyte characters has been fixed. 10-08-04 A bug which caused an exception when processing scripts compiled with shcomp -n has been fixed. 10-08-02 Tests using very small buffer sizes uncovered a number of bug most connected with here documents which have been fixed. 10-07-27 The format modifier , used for digit grouping with d and f formats has been documented. 10-07-26 cd '' now produces and error rather than changing to the current directory. 10-07-26 A bug in multi-byte locales which the last character of a multi-byte character is a \ or pattern character which could occur when the character was the last character of a command substitution has been fixed. 10-07-23 Another bug in the processing of ${var:offset;len} in multi-byte locales when len is larger than the number of characters has been fixed. 10-07-23 Many coding changes have been made to eliminate most of the uses of global variables in the shell code. 10-07-22 Fixed a bug in which discipline functions were not being invoked when it was invoked as ref.discipline where ref was a name reference to an array instance. 10-07-22 Fixed a bug in which discipline functions were not being invoked it was invoked on a two dimensional array, i.e., arr[5][9].discipline. 10-07-19 Fixed a buffering problem which occured when running a script with ssh and the parent ssh process is killed. 10-07-14 Modifed the parser to treat ((...)) inside [[...]] as ( (...) ) to that it is a nested (...). 10-07-09 A bug in the handling of process substitution inside command substitution as part of a pipeline has been fixed. 10-07-07 A bug in the output for compound variables containing multi-dimensional arrays has been fixed. 10-07-06 ksh now recovers from changes made by bash to the history file without loosing history commands. 10-06-25 A bug in which a large here document containing command substitutions of a dynamically loaded function that contained a here document could get truncated has been fixed. 10-06-24 If after executing a script found in FPATH, if a function, builtin, or type name corresponding to that script is not defined, the shell now outputs an error message and returns value 126. 10-06-23 Floating point functions that happened to return integer values were being treated as if the function returned integers so that integer division could be used instead of floating point division. 10-06-22 Fixed a bug in earlier ksh93u in which an arithmetic assignment to a variable in the global scope would instead create a local variable if the variable had an attribute but did not have a value. 10-06-18 Modified trap handling so that if the same signal is received when executing the handler, it is deferred until the handler completes. 10-06-16 Fixed a bug in which ulimit -v was setting the the cpu limit on Linux. 10-06-14 +The command 'typeset -T' now generates the list of type definitions in a format that can be used as input to the shell. 10-06-09 Put in patch from Solaris for output quoting with %q. 10-06-09 +Made changes to the NAMESPACE compile option so that it now seems to work. With this option, namespace { command;} will run command in the namespace .name so that all variables and functions created by command are accessable outside the name space via .name.var and .name.fun. Variables and functions that are not in the namespace are not modifed when runnning command. 10-06-07 Change most internal interfaces to take Sh_t* argument. 10-06-03 +Types can be loaded on first reference by putting defintions in PFPATH. 10-06-03 +The shell is now able to parse commands which use type statements before the typeset -T command to define the type executes. 10-06-03 A bug in the quoting for name reference declarations which did not properly handle [ and ] in subscripts for associative arrays. 10-06-02 A bug in which a discipline function defined by a type instance to override the default was not being registered has been fixed. 10-06-02 A bug in which read -C of an associative array of compound variables was not working has been fixed. 10-06-02 A bug in which the error message for an unset parameter with set -u did not contain the name of the variable has been fixed. 10-06-01 A bug in typeset -m for moving an indexed array instance to a variable has been fixed. 10-06-01 A bug in which caused memory to be freed twice when unset was called for an indexed array that had get or set disciplines has been fixed. 10-06-01 A bug in which the %b format of printf was not preserving NUL bytes with \0 has been fixed. 10-06-01 A bug in the handling of name references to array variables in arithmetic expressions has been fixed. 10-05-28 Fixed bugs in changing attributes for two dimensional arrays. 10-05-28 Eliminated a few unreferenced variables and a reference to uninitialized memroy. 10-05-27 Rewrote the subshell code to avoid using pipes an many cases. 10-05-24 Fixed a bug which cause an exception when both -l and -s were specified with typeset -i. 10-05-21 Inputting of three dimensional indexed arrays with ( ( (...)...)...) was not working and has been fixed. 10-05-21 A bug in which adding the attributes -Ai to a variable via a name reference could cause the value to display incorrectly has been fixed. 10-05-21 A bug in which using $var inside ((...)) did not work when var was a hex float variable. 10-05-20 +The compile option SHOPT_EDPREDICT has been added. When this option is on, as you type a line beginning with a # the following characters are treated as a shell pattern and cause matching lines from the history file to be displayed as a numbered list as you type. You can scroll up and down this list or you can use nTAB to make this the current line (n defaults to 1 of ommitted) or n to execute. 10-05-20 A bug which caused an exception when multiple levels of composite functions in arithemtic expressions has been fixed. 10-05-19 <<< with an empty string no longer gives an error. 10-05-19 A bug in arithmetic evaluation when a name reference to an array instance was used has been fixed. 10-05-14 A bug in which the shell treats a valid index array assignment, typeset -a x=(foo (x=3;y=4) bar) as a syntax error has been fixed. 10-05-13 A bug in creating name references to assocative array variable after a lookup of one of its elements has been fixed. 10-05-12 Two bugs in the handling of function static type variables in subshells have been fixed. One could cause an exception and the other would leave side effects in the parent shell. 10-05-10 A bug in which static variables in functions were not being saved and restored properly when running subshells has been fixed. 10-05-05 A bug in which print -v did not work correctly when an operand was an indexed array element refering to a compound variable has been fixed. 10-05-05 A change to improve performace by special casing empty string assignments to avoid repeated malloc() and free(). 10-05-05 A bug in which creating a name reference to a non-existant associative array element would create the array element has been fixed. 10-05-04 A bug in which name references to static variables in the static scope were not found has been fixed. 10-04-30 Do not use socketpair() on systems that implement ioctl(I_PEEK) on pipes. 10-04-29 +When the current job pool is set, coprocess are run in a job pool. 10-04-28 A type defined with a member foo that is an associative array without elements followed by an expansion ${bar.foo[a]} and an assignment bar.foo[a]=b, no longer indicates that ${#bar.foo[@]} has 0 members. 10-04-27 Another bug in which a nested command substitution could hang if it generated too much data has been fixed. 10-04-26 A type defined with a member that is an indexed array without elements would behave as if the 0th element of each instance was defined after a non-zero element was specified and this has been fixed. 10-04-26 A bug in which types defined in a subshell were not undefined when the subshell completed has been fixed. 10-04-23 For file completion in commmand line editing, file names starting with # are now escaped so that they are not treated as comments. 10-04-23 A bug in which ${t.var:=value}, where t is an instance of a type variable, could assign value to the type variable rather than to the type instance has been fixed. 10-04-23 +Added &| which can be used in place of | to have portions of a pipeline executed in the pool. 10-04-22 +The .sh.pool variable was added for use with job pools. 10-04-22 A bug in which a nested command substitution could hang if it generated too much data has been fixed. 10-04-20 A bug which corrupted one byte of memory when read was called with reads that did not use a delimiter has been fixed. 10-04-19 The display of a compound variable with an embedded array with attributes was sometimes not working correctly and has been fixed. 10-04-16 A bug in which attributes were not be propogated to elements in an associative array has been fixed. 10-04-15 A bug which caused scripts containing user defined math functions to fail to compile with shcomp has been fixed. 10-04-15 +Job pools have been added with the SHOPT_COSHELL compilation option. A job pool allows a collection of background jobs to run either locally or remotetly and to be managed as a unit. The command '& name ...' creates or uses a named job pool for subsequent background jobs. kill, wait, and jobs allow the pool name as operands. 10-04-14 A bug in which a coprocess connection could terminate prematurely when running a nested subshell has been fixed. 10-04-12 +Enumeration constants can be used in arithmetic expressions with the ==, != and = operators when the left hand side is an enum variable and the right hand side is an enumeration constant. 10-04-07 A bug in which setting the trap on CHLD to ignore could cause an incorrect exit status has been fixed. 10-04-06 A bug in which LINENO was not incremented for a here-document when the here-document word was followed by a comment has been fixed. 10-04-06 The optimization that execs the last process of a script rather than creating a new process has been removed when a trap on interrupt has been set. 10-04-06 Unsetting the 'C', 'A' or 'a' typeset attribute now produces an error message rather than generating an exception. 10-04-06 A bug in which .sh.name contained the subscript and .sh.subscript was empty in some cases with discipline functions on array instances has been fixed. 10-04-05 A bug in the edit modes where preceding the interrupt character with the literal next character did not work has been fixed. 10-04-05 A bug in the creation of type instances of arrays which could cause an exception has been fixed. 10-03-30 A bug in the display of a compound variable containing an indexed array of compound variables has been fixed. 10-03-24 +Arithmetic functions can be defined using the shell function syntax, 'function .sh.math.name x y z{...}' , where name is the function name 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. 10-03-24 A bug in which integer division was mistakenly used when the numerator was a binary operator with the first operand floating point and the second integer, e.g. (.1**3)/3, has been fixed. 10-03-24 The >; file operator was modified so that the temporary file is created in the same physical directory as file. 10-03-23 A warning message was added to sh -n when $var was used inside ((...)) instead of var. 10-03-19 fmin was added to the list of math function on the man page. 10-03-19 Fixed the return value for unalias when the alias did not exist. 10-03-19 A bug in which the SHLVL variable exported the value it had on input rather than the incremented value has been fixed. 10-03-19 A bug which causes whence -q to go into an infinite loop has been fixed. 10-03-19 Removed space between Stopped message and (SIGTTIN) and (SIGTTOUT). 10-03-17 Modified profile shell execution so that when builtins that correspond to executable have extended attributes, they are executed by pfksh instead of being treated as built-ins. 10-03-16 A bug in whence -a which produced duplicate lines of output has been fixed. 10-03-16 A bug in the handling of process groups in monitor mode for command substitutions has been fixed. 10-03-15 Fixed a bug in which read -u[fd] could cause the shell to core dump when fd was greater than open_max. 10-03-15 +Modified the shell I/O so that the shell will not fail if the ulimit for open_max is increased as part of the script. 10-03-12 A bug in which a here-document containing command substitutions that contained here-documents did not process correctly has been fixed. 10-03-12 A bug in which the terminal is not restored to cannonical mode after read times out when in a multibyte locale with no edit mode enabled has been fixed. 10-03-05 --- Release ksh93t+ --- 10-03-05 A varibale unset memory leak has been fixed and

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.

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 >#.

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\n' 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 $HOME/.kshrc for interactive shells. 03-11-21 A bug introduced in ksh93o in which the DEBUG trap could get disabled after it triggered has been fixed. 03-11-04 A bug in which using arithmetic prefix operators ++ or -- on a non-lvalue could cause a core dump has been fixed. 03-11-04 A bug in which leading zeros were stripped from variable expansions within arithmetic computation to avoid being treated as octal constants when they should not have, has been fixed. 03-10-08 A bug introduced in ksh93o in which a large here document inside a function definition could get corrupted has been fixed. 03-09-22 A bug in which the .get discipline function was not being called when a string variable was implicitly referenced from within a numerical expression has been fixed. 03-09-22 A bug in which a script without a leading #! could get executed by /bin/sh rather than the current shell on some systems has been fixed. 03-09-12 +To improve conformance with ksh88, leading zeros will be ignored when getting the numerical value of a string variable so that they will not be treated as octal constants. 03-09-03 +The builtin kill command now processes obsolete invocations such as kill -1 -pid. 03-09-02 The restriction on modifying FPATH in a restricted shell (sh -r) has been documented. 03-09-02 +The restricted shell (sh -r) has been modified to disallow executing command -p. 03-08-07 A bug in which the KEYBD trap was not being invoked when characters with the 8th bit set has been fixed. 03-08-02 A parser bug introduced in ksh93o which caused the character after () in a Posix function definition to be skipped when reading from standard input has been fixed. 03-08-01 A bug in which "${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.

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. 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.

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 ERR was set, and the command inside () modified the trap, then 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 fixed. 01-10-11 An optimization bug in which ${!x) was treated as invariant in a for loop has been fixed. 01-10-11 Unsigned integer variables in bases other than 10 are printed now expand in that base with the base prefix. 01-10-10 A number of typos in the self generating man pages for shell built-ins have been fixed. 01-10-04 The self generated man pages for hist and fc were not working correctly and have been fixed. 01-10-03 Yet another optimizer bug in which shell patterns were 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. 01-06-04 The evaluation of the PS1 prompt no longer effects the value 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 \e, \cX, \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 \ 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 run on read-only file systems. 00-04-17 +Modified printf to handle '%..Xc' and '%..Xs' options where X is not an alpha character. Previous versions core dumped with this. 00-04-10 +Changes to multibyte editing code were made to use standard ISO C functions rather than methods devised before the standard. 00-04-09 Add %H options to printf to output strings with <"'&\t> properly converted for use in HTML and XML documents. 00-04-07 +Modified getopts builtin to handle \f...\f in usage string by invoking specified function. 00-04-04 Added self generating man pages for bg, fc, fg, disown, jobs, hist, let, ., and ulimit. 00-03-30 +The append operator += has been added and can be used for all assignments, strings, arrays, and compound variables. 00-03-30 +Code was modified in several places to support automatic generation of C locale dictionaries. 00-03-28 A bug in which the set and trap commands invoked with --name type arguments would terminate the invoking script has been fixed. 00-03-27 A bug in which the library path variable was not updated correctly on some systems as described in the 'g' point release has been fixed. 00-03-07 printf now returns a non-zero exit status when one of its arguments cannot be converted to the given type. 00-03-05 The return value and error message for a command that was found on the path but was not executable was set incorrectly. 00-03-05 A prototype for ioctl() was removed from the vi edit mode. 00-01-28 --- Release ksh93i --- 00-01-28 +Most of the built-in commands and ksh itself are now self documenting. Running command --man will produce screen output. Running command --html produces the man page in html format. 00-01-28 +The getopts builtin can process command description strings to produce man pages. 00-01-28 A bug in which a script could terminate when getopts encountered an error when invoked inside a function has been fixed. 00-01-28 When a symbolic link was specified as the name of the script to invoke by name, the value of $0 was set to the real file name rather than the link name in some cases and this has been fixed. 00-01-28 A bug in which the precision given as an argument 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. 99-03-31 +When performing pathname expansion, the shell checks to see whether each directory it reads is case sensitive or not, and performs the matching accordingly. 99-03-31 +The %T format for printing formatted date/time. 99-03-31 +The emacs and vi modes now handle arrow keys when they use standard ANSI escape sequences. 99-03-31 +The TAB key can be used for completion in emacs and viraw mode. 99-03-31 A bug in setting .sh.editchar during the KEYBD trap for the MULTIBYTE option was fixed in release ksh93h. 99-03-31 A bug in shcomp for compilation of unary operators with [[...]] has been fixed. 99-03-31 A bug in which the value of $? was changed when executing a keyboard trap has been fixed. 99-03-31 The handling of SIGCHLD has been changed so that the trap is not triggered while executing trap commands to avoid recursive trap calls. 99-03-31 A bug in which a local variable in a function declared readonly would generated an error when the function went out of scope has been fixed. 99-03-31 A bug in which \ entered from the keyboard with the KEYBD trap enabled has been fixed. 99-03-31 The error message for a misplaced ((, for example print ((3), was often garbled and has been fixed. 99-03-31 A bug in the KEYBD trap in which escape sequences of the form [#~ were not being handled as a unit has been fixed. 99-03-31 A bug in which ksh would consider expressions like [[ (a) ]] as syntax errors has been fixed. 99-03-31 A function defined as foo() without a function body was not reported as a syntax error. 99-03-31 A bug in which ksh could run out of file descriptors when 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.
