This is a partial history of this shell gleened from old change logs and
|
|
||||||
readmes (most of which are still in the misc directory) and the source
|
|
||||||
code. Hopefully it is correct and no contributors have been left out
|
|
||||||
(file a bug report if you spot a problem :-)).
|
|
||||||
|
|
||||||
Release history:
|
|
||||||
* Eric Gisin (egisin@math.uwaterloo.ca), created pdksh, using
|
|
||||||
Charles Forsyth's public domain V7 shell as a base; also used parts
|
|
||||||
of the BRL shell (written by Doug A Gwyn, Doug Kingston, Ron Natalie,
|
|
||||||
Arnold Robbins, Lou Salkind, and others?, circa '87; the parts used in
|
|
||||||
pdksh included getopts, test builtin, ulimit, tty setting/getting, emacs
|
|
||||||
editing, and job control; the test builtin was based on code by Erik
|
|
||||||
Baalbergen).
|
|
||||||
'87..'89 ?

|
||||||
[This file is the generic GNU autoconf/configure installation description,
|
|
||||||
see the README for pdksh specific configuration/installation information]
|
|
||||||
|
|
||||||
This is a generic INSTALL file for utilities distributions.
|
|
||||||
If this package does not come with, e.g., installable documentation or
|
|
||||||
data files, please ignore the references to them below.
|
|
||||||
|
|
||||||
The `configure' shell script attempts to guess correct values for
|
|
||||||
various system-dependent variables used during compilation, and
|
|
||||||
creates the Makefile(s) (one in each subdirectory of the source
|
|
||||||
directory). In some packages it creates a C header file containing
|
|
||||||
system-dependent definitions. It also creates a file `config.status'
|
|
||||||
that you can run in the future to recreate the current configuration.
|
|
||||||
|
|
||||||
To compile this package:
|
|
||||||
|
|
||||||
1. Configure the package for your system.
|
|
||||||
|
|
||||||
Normally, you just `cd' to the directory containing the package's
|
|
||||||
source code and type `./configure'. If you're using `csh' on an old
|
|
||||||
version of System V, you might need to type `sh configure' instead to
|
|
||||||
prevent `csh' from trying to execute `configure' itself.
|
|
||||||
|
|
||||||
Running `configure' takes awhile. While it is running, it
|
|
||||||
prints some messages that tell what it is doing. If you don't want to
|
|
||||||
see any messages, run `configure' with its standard output redirected
|
|
||||||
to `/dev/null'; for example, `./configure >/dev/null'.
|
|
||||||
|
|
||||||
To compile the package in a different directory from the one
|
|
||||||
containing the source code, you must use a version of `make' that
|
|
||||||
supports the `VPATH' variable, such as GNU `make'. `cd' to the
|
|
||||||
directory where you want the object files and executables to go and run
|
|
||||||
the `configure' script. `configure' automatically checks for the
|
|
||||||
source code in the directory that `configure' is in and in `..'. If
|
|
||||||
for some reason `configure' is not in the source code directory that
|
|
||||||
you are configuring, then it will report that it can't find the source
|
|
||||||
code. In that case, run `configure' with the option `--srcdir=DIR',
|
|
||||||
where DIR is the directory that contains the source code.
|
|
||||||
|
|
||||||
By default, `make install' will install the package's files in
|
|
||||||
`/usr/local/bin', `/usr/local/man', etc. You can specify an
|
|
||||||
installation prefix other than `/usr/local' by giving `configure' the
|
|
||||||
option `--prefix=PATH'. Alternately, you can do so by consistently
|
|
||||||
giving a value for the `prefix' variable when you run `make', e.g.,
|
|
||||||
make prefix=/usr/gnu
|
|
||||||
make prefix=/usr/gnu install
|
|
||||||
|
|
||||||
You can specify separate installation prefixes for
|
|
||||||
architecture-specific files and architecture-independent files. If you
|
|
||||||
give `configure' the option `--exec-prefix=PATH' or set the `make'
|
|
||||||
variable `exec_prefix' to PATH, the package will use PATH as the prefix
|
|
||||||
for installing programs and libraries. Data files and documentation
|
|
||||||
will still use the regular prefix. Normally, all files are installed
|
|
||||||
using the same prefix.
|
|
||||||
|
|
||||||
Some packages pay attention to `--with-PACKAGE' options to
|
|
||||||
`configure', where PACKAGE is something like `gnu-as' or `x' (for the
|
|
||||||
X Window System). They may also pay attention to `--enable-FEATURE'
|
|
||||||
options, where FEATURE indicates an optional part of the package. The
|
|
||||||
README should mention any `--with-' and `--enable-' options that the
|
|
||||||
package recognizes.
|
|
||||||
|
|
||||||
`configure' also recognizes the following options:
|
|
||||||
|
|
||||||
`--help'
|
|
||||||
Print a summary of the options to `configure', and exit.
|
|
||||||
|
|
||||||
`--quiet'
|
|
||||||
`--silent'
|
|
||||||
Do not print messages saying which checks are being made.
|
|
||||||
|
|
||||||
`--verbose'
|
|
||||||
Print the results of the checks.
|
|
||||||
|
|
||||||
`--version'
|
|
||||||
Print the version of Autoconf used to generate the `configure'
|
|
||||||
script, and exit.
|
|
||||||
|
|
||||||
`--x-includes=DIR'
|
|
||||||
X include files are in DIR.
|
|
||||||
|
|
||||||
`--x-libraries=DIR'
|
|
||||||
X library files are in DIR.
|
|
||||||
|
|
||||||
`configure' also accepts and ignores some other options.
|
|
||||||
|
|
||||||
On systems that require unusual options for compilation or linking
|
|
||||||
that the package's `configure' script does not know about, you can give
|
|
||||||
`configure' initial values for variables by setting them in the
|
|
||||||
environment. In Bourne-compatible shells, you can do that on the
|
|
||||||
command line like this:
|
|
||||||
|
|
||||||
CC='gcc -traditional' LIBS=-lposix ./configure
|
|
||||||
|
|
||||||
On systems that have the `env' program, you can do it like this:
|
|
||||||
|
|
||||||
env CC='gcc -traditional' LIBS=-lposix ./configure
|
|
||||||
|
|
||||||
Here are the `make' variables that you might want to override with
|
|
||||||
environment variables when running `configure'.
|
|
||||||
|
|
||||||
For these variables, any value given in the environment overrides the
|
|
||||||
value that `configure' would choose:
|
|
||||||
|
|
||||||
- Variable: CC
|
|
||||||
C compiler program. The default is `cc'.
|
|
||||||
|
|
||||||
- Variable: INSTALL
|
|
||||||
Program to use to install files. The default is `install' if you
|
|
||||||
have it, `cp' otherwise.
|
|
||||||
|
|
||||||
For these variables, any value given in the environment is added to
|
|
||||||
the value that `configure' chooses:
|
|
||||||
|
|
||||||
- Variable: DEFS
|
|
||||||
Configuration options, in the form `-Dfoo -Dbar...'. Do not use
|
|
||||||
this variable in packages that create a configuration header file.
|
|
||||||
|
|
||||||
- Variable: LIBS
|
|
||||||
Libraries to link with, in the form `-lfoo -lbar...'.
|
|
||||||
|
|
||||||
If you need to do unusual things to compile the package, we encourage
|
|
||||||
you to figure out how `configure' could check whether to do them, and
|
|
||||||
mail diffs or instructions to the address given in the README so we
|
|
||||||
can include them in the next release.
|
|
||||||
|
|
||||||
2. Type `make' to compile the package. If you want, you can override
|
|
||||||
the `make' variables CFLAGS and LDFLAGS like this:
|
|
||||||
|
|
||||||
make CFLAGS=-O2 LDFLAGS=-s
|
|
||||||
|
|
||||||
3. If the package comes with self-tests and you want to run them,
|
|
||||||
type `make check'. If you're not sure whether there are any, try it;
|
|
||||||
if `make' responds with something like
|
|
||||||
make: *** No way to make target `check'. Stop.
|
|
||||||
then the package does not come with self-tests.
|
|
||||||
|
|
||||||
4. Type `make install' to install programs, data files, and
|
|
||||||
documentation.
|
|
||||||
|
|
||||||
5. You can remove the program binaries and object files from the
|
|
||||||
source directory by typing `make clean'. To also remove the
|
|
||||||
Makefile(s), the header file containing system-dependent definitions
|
|
||||||
(if the package uses one), and `config.status' (all the files that
|
|
||||||
`configure' created), type `make distclean'.
|
|
||||||
|
|
||||||
The file `configure.in' is used to create `configure' by a program
|
|
||||||
called `autoconf'. You only need it if you want to regenerate
|
|
||||||
`configure' using a newer version of `autoconf'.

options.h file). Shell can be configured as a (almost) plain bourne
|
|
||||||

|
|
||||||
in the tests/ directory (contains a perl script which sets up a test
|
|
||||||
environment and runs tests, and a bunch of tests).
|
|
||||||
|
|
||||||
|
|
||||||
Version 5.2.3
|
|
||||||
|
|
||||||
* bug fixes

|
|
||||||
* cd: two argument form works again.
|
|
||||||
* special commands taking assignments (alias,set,etc.): field splitting,
|
|
||||||
file globbing, etc. suppressed only for args that look like assignments.
|
|
||||||
* command: -V now finds reserved words.
|
|
||||||
|
|
||||||
* added support for Korn's /dev/fd tests
|
|
||||||
|
|
||||||
* new compile time option: DEFAULT_ENV - if defined, it names a file to
|
|
||||||
include if $ENV is not set.
|
|
||||||
|
|
||||||
* test -o option: if option starts with a !, the test is negated. The test
|
|
||||||
always fails if the option doesn't exist (so [ -o foo -o -o !foo ] is true
|
|
||||||
iff option foo exists).
|
|
||||||
|
|
||||||
* new option: set -o nohup (currently on by default) - if set, running jobs
|
|
||||||
are not kill -HUP'd when a login shell exits; if clear, they are. In
|
|
||||||
future, this will be clear by default (to act like at&t ksh) - if you don't
|
|
||||||
(won't) like this, add "[ -o !nohup ] && set -o nohup" to your .profile.

|
|
||||||
* `r r' no longer repeats r command forever.
|
|
||||||
* make depend no longer generates backslash followed by a blank line.
|

|
|
||||||
* if the ] is missing in a pattern, the [ matches the [ character.
|
|
||||||
* syntax errors in test no longer have two newlines.
|
|
||||||
* in vi, G now goes to the oldest history (was newest).
|
|
||||||
* configuration: test for sys_siglist now harder for optimizers to break.
|
|
||||||

|
|
||||||
|
|
||||||
Version 5.0.9
|
|
||||||
|
|
||||||
* bug fixes
|
|
||||||
* FOO is put in the environment for FOO=bar exec blah.
|
|
||||||
* compiles under QNX and with dmake.
|
|
||||||
* the file pattern [!a--]* is now invalid (POSIX) (used to match everything)
|
|
||||||
* echo "${foo:-"a"}*" no longer the same as echo a*.
|
|
||||||
* alternation (brace expansion) fixes:
|
|
||||||
* brace expansion done after variable expansion, as in csh/at&t ksh.
|
|
||||||
* `echo a{b,c' no longer gives "Missing }" error (it echos a{b,c).
|
|
||||||
* expansion only done if there is a comma (ie, `echo {a}' prints {a}).
|
|
||||||
* globbing/expansion code passes 0x80 unharmed.
|
|
||||||
* "echo ${XX=a*b}" no longer sets XX to "a\200*b".
|
|
||||||
* "echo ${unset-a*b}" no longer has \200 in the error message.
|
|
||||||
* bad substitution error generated for things like ${x:a}, ${x^a}, etc.
|
|
||||||
* `x="a cdef"; echo ${x#a c}' now prints "def" instead of "a a cdef".
|
|
||||||
* on systems where /etc/passwd//// is a valid name, echo /etc/pass*/ no
|
|
||||||
longer matches /etc/passwd.
|
|
||||||
* trace output (set -x) flushed correctly, PS4 initialized.
|
|
||||||
* ulimit output ungarbled, code to use {set,get}ulimit (if available)
|
|
||||||
enabled.
|
|
||||||
* tilde expansion done in word part of ${foo-~/bar}
|
|
||||||
* when reading stdin (ie, ksh -s), no longer reads too much.
|
|
||||||
* shell handles i/o redirection and errors in builtin commands as per
|
|
||||||
POSIX (still have to sort out variable assignment errors).
|
|
||||||
* starting jobs that save/change/restore tty settings in the background
|
|
||||||
no longer messes up tty settings when job finishes.
|
|
||||||
* the pattern [a'-'z] now matches three characters, not 26, and
|
|
||||||
the pattern [ab']'] also matches three characters.
|
|
||||||
|
|
||||||
* a mostly complete man page! (work is still in progress)
|
|
||||||
|
|
||||||
* quoting inside $(..) mostly works.
|
|
||||||
|
|
||||||
* error reporting has been orthogonalized.
|
|
||||||
|
|
||||||
* brace expansion on by default (can be disabled with set +o braceexpand, or
|
|
||||||
set -o posix).
|
|
||||||
|
|
||||||
* output of "set -o" now fits on a normal screen.
|
|
||||||
|
|
||||||
* co-processes added (|&, read -p, print -p, etc.).
|
|
||||||
|
|
||||||
* restricted mode added (for what its worth).
|
|
||||||
|
|
||||||
* vi now prints meta characters with M- prefix, unless vi-show8 option is on.
|
|
||||||
|
|
||||||
Version 5.0.8
|
|
||||||
|
|
||||||
* bug fixes
|
|
||||||
* two problems in fc (introduced in 5.0.7)
|
|
||||||
* install target in Makefile missing a dollar
|
|
||||||
|
|
||||||
Version 5.0.7
|
|
||||||
|
|
||||||
* POSIX command command added
|
|
||||||
|
|
||||||
* a few bug fixes
|
|
||||||
* now compiles with various options undefined (eg, VI, EMACS, JOBS).
|
|
||||||
* fixed typos in Makefile.in (maxext -> manext) and ksh.1 (\f -> \fP).
|
|
||||||
* CLK_TCK defined to correct value for FreeBSD 1.1.5 (and earlier?).
|
|
||||||
* original process group restored when an exec is done.
|
|
||||||
* the exit value of set is that of the last $(...) on the command line.
|
|
||||||
* ditto for a command with no command (eg, x=`false`).
|
|
||||||
* command variable assignments done before path search (so PATH=... x works)
|
|
||||||
and are added as they are processed (so A=1 B=$A works).
|
|
||||||
* variable assignments infront of function calls are exported to programs
|
|
||||||
inside the function.
|
|
||||||
* aliases with trailing space are only honoured in command contexts
|
|
||||||
if in posix mode.
|
|
||||||
|
|
||||||
* make depend target added; install target warns if ksh not in /etc/shells.
|
|
||||||
|
|
||||||
* set -o bgnice now does something.
|
|
||||||
|
|
||||||
* vi mode: ESC is no longer a file completion command (too annoying).
|
|
||||||
|
|
||||||
Version 5.0.6
|
|
||||||
|
|
||||||
* most reported bugs/problems fixed (all but two).
|
|
||||||
|
|
||||||
* temporary files now created in $TMPDIR (if it is a sane path).
|
|
||||||
|
|
||||||
Version 5.0.5
|
|
||||||
|
|
||||||
* function parsing POSIXized (function bodies can be any compound command,
|
|
||||||
redirections after functions effect function invocation, not the
|
|
||||||
instantiation, the () in a function definition now parsed as two tokens).
|
|
||||||
|
|
||||||
* exit bultin now does stopped jobs check.
|
|
||||||
|
|
||||||
* set -p/-o priviliged supported.
|
|
||||||
|
|
||||||
* test builtin now believed to be completely posix.
|
|
||||||
|
|
||||||
* a default path is now used when PATH is not set (defined in options.h).
|
|
||||||
|
|
||||||
Version 5.0.4
|
|
||||||
|
|
||||||
* configuration checks for buggy opendir()s and setpgrp()s.
|
|
||||||
|
|
||||||
* autoloading functions now supported.
|
|
||||||
|
|
||||||
* functions can safely redefine themselves.
|
|
||||||
|
|
||||||
Version 5.0.3
|
|
||||||
|
|
||||||
* hash command changed to "alias -t"; whence -p added; print -s added
|
|
||||||
(all as in at&t ksh); unalias -a added (POSIX).
|
|
||||||
|
|
||||||
* test builtin POSIX complient
|
|
||||||
|
|
||||||
* TMOUT parameter supported (at&t ksh: timeout interactive shells)
|
|
||||||
|
|
||||||
Version 5.0.2
|
|
||||||
|
|
||||||
* trap/error handling changed to eliminate longjmp()s from signal handlers;
|
|
||||||
trap ERR added.
|
|
||||||
|
|
||||||
* ksh conditional expressions ([[ .. ]]) supported.
|
|
||||||
|
|
||||||
* arithmetic expressions (let, $((..)), etc.) now understand full C
|
|
||||||
integer expressions (except ++/-- and sizeof()).
|
|
||||||
|
|
||||||
* typeset -L -R -Z -u -l added (as in at&t ksh)
|
|
||||||
|
|
||||||
* at&t/posix $(( .. )) arithmetic expansions supported.
|
|
||||||
|
|
||||||
Version 5.0.1
|
|
||||||
|
|
||||||
* set -e no longer effects commands executed as part of if/while/until/&&/||/!
|
|
||||||
condition.
|
|
||||||
|
|
||||||
* posix ! keyword now recognized.
|
|
||||||
|
|
||||||
* posix getopts; if not in posix mode, getopts will accept options starting
|
|
||||||
with + (at&t kshism)
|
|
||||||
|
|
||||||
* syntax error messages improved (says what was unexpected/unmatched)
|
|
||||||
|
|
||||||
Version 4.9+mun.5
|
|
||||||
|
|
||||||
* all known bugs related to job control fixed:
|
|
||||||
* fg,bg,jobs,wait,kill commands fully POSIX complient
|
|
||||||
* signals are no longer reported for foreground jobs killed by SIGINT and
|
|
||||||
SIGPIPE
|
|
||||||
* pipeline process groups now created more reliablely (was a problem
|
|
||||||
if first process exited before second process exec'd).
|
|
||||||
* "(: ; cat /etc/termcap) | sleep" nolonger hangs
|
|
||||||
|
|
||||||
* save/restore tty mode if command succeeds/fails, respectively. Edit
|
|
||||||
mode (emacs,vi) no longer use old tty mode information
|
|
||||||
|
|
||||||
* test command: added -h
|
|
||||||
|
|
||||||
* alternations option renamed to braceexpand (eg, use set -o braceexpand).
|
|
||||||
Old usage (set -o alternations) still accepted (will disappear in next
|
|
||||||
version).
|
|
||||||
|
|
||||||
* trap/kill now accept upper and lower case signal names.
|
|
||||||
|
|
||||||
Version 4.9+mun.3
|
|
||||||
|
|
||||||
* here documents in functions now work properly
|
|
||||||
|
|
||||||
* read command: added -s option, use REPLY if no variable specified
|
|
||||||
|
|
||||||
* don't accept "while command; done" as a valid command
|
|
||||||
|
|
||||||
* fg,bg,jobs,wait,kill commands mostly POSIX complient.
|
|
||||||
|
|
||||||
* unset command: added POSIX -v option
|
|
||||||
|
|
||||||
* set command: added -A option
|
|
||||||
|
|
||||||
* handle ${array[@]} and ${array[*]}
|
|
||||||
|
|
||||||
* compiles with old bsd 4.2 compiler (pcc)
|
|
||||||
|
|
||||||
* new versions of etc/profile and etc/ksh.profile
|
|
||||||
|
|
||||||
Version 4.9+mun.2 (versus 4.9)

|
|
||||||
|
|
||||||
* now uses GNU autoconf for compilation.
|
|
||||||
|
|
||||||
* no longer uses stdio FILE *'s for I/O redirection (most stdio
|
|
||||||
usage has been removed). Solves many porting problems caused by
|
|
||||||
dup'd file descriptors, forked processes and exiting.
|
|
||||||
|
|
||||||
* removed lint from code (compiles with very few warning with gcc -O -Wall
|
|
||||||
-Wno-comment)
|
|
||||||
|
|
||||||
* has array support (needs work but is pretty functional).
|
|
||||||
|
|
||||||
* ulimit command now more functional on more machines. Compatible with at&t ksh.
|
|
||||||
|
|
||||||

||||||
|
|
||||||
