# File name completion (^X,*) does not mesh well with cd and

# doing the actual chdir(), while file name completion does
# not do the simplification. E.g., you are in directory A
# which has a symbolic link to directory B, you create a file
# called foobar and you then cd to the symlink to B, and type
# $ echo ../foo^X

Fri Dec 3 21:39:47 1993 Piercarlo Grandi (pcg@aber.ac.uk)
* polished 4.9 for linux; corrected a terrible, linux
specific performance bug that caused all streams to
become unbuffered; made emacs.c more understandable.
With 4.9 pdksh is twice as fast and one third the size
of bash 1.13, and has most of the relevant functionality.
To me it is a drop-in replacement.
Sat May 8 15:55:24 1993 Simon J. Gerraty (sjg@zen.void.oz.au)
* Ported to 386bsd - sh directory only, stc/* not needed.
Sat Aug 1 17:11:24 1992 Simon J. Gerraty (sjg@zen)
* Incorporated massive contribution from Peter Collinson
Refer to Changes.pc
* Incorporated Emacs-style completion provided by
Neil.Smithline@eng.sun.com this a bit nicer than the standard ksh
file completion.
Sun May 3 17:50:03 1992 Simon J. Gerraty (sjg@zen)
* Updated MACHINES.
* Placed source under CVS. This should help with processing fixes
from the field.
Sat Apr 25 10:53:20 1992 Simon J. Gerraty (sjg@zen)
* Getting ready for 4.3 release.
Fri Nov 22 22:24:29 1991 Simon J. Gerraty (sjg at zen)
* Cleaned up the build process slightly. Makefiles in ./std tree
now maintain objects within the libraries rather than simply
building the .o's and archiving them. Of course the make(1) used
must know how to maintain libraries :-)
* Added bug.report as a template for bug reporting.
* Source in ./sh can be built independently of ./std tree if
desired. See comments in ./sh/Makefile.
* As originally distributed some of libstdc.a was not used and
libposix.a was not used at all. On Sun's this highlighted a bug
(incompatibility) in the times() call. Now the ./std/libs are
used fully, and the supplied times() call functions as expected.

Changes to the PD ksh since last time:
- clean up the option configuration stuff. Options in config.h should
now just be #define'd or not, not #define'd to 1 if you want them
and 0 if you don't
- ksh now uses the shell specified by the variable EXECSHELL to run
shell scripts. If EXECSHELL is unset or null it defaults to
/bin/sh. It does a path lookup on the value, so if you set it to
``ksh'' the ksh will run all scripts that don't start with #!. It
seems to run most sh scripts fine (now). I'd be very interested to
hear your experiences if you try this out, as for my next trick I'd
like to make ksh just fork itself to run scripts, which would speed
things up, and allow exportable functions and aliases (like he real
ksh). Just to assure you that it can do some hairy sh scripts, both
CC and coco work with ksh.
EXECSHELL won't work if the system's exec(2) call runs scripts...
- the ``let'' builtin now evaluates null or unset vars to 0, as per
The Book
- Various memory allocation/use problems were cleaned up. Hopefully
you'll never see the ``freeing free object'' error again (if you've
ever seen it).
- the ``test'' builtin is now much more tolerant in parsing its
arguments. This was to make it like the /bin/sh test.
- Temp files (for here documents or ``fc'') are now mode 0600
- Some format strings in the tree printing routines got ``expanded''
into SCCS keywords, so the results of``type <function>'' were
gave you interesting things like the time I last checked in the
file. This has been fixed.
- ``unset -f'' now really does unset functions.
- the ``trailing blank or tab in alias definition'' feature now works.
- A bug in command completion was fixed. Note command completion only
works on commands that have been hashed, so you want to ``set -h''
in your .kshrc, and you may wish to force hashing of some common
commands with the ``hash'' builtin.
- ``echo $$ | cat'' now works as in /bin/sh
Not new features, but newly discovered bugs:
- Local functions don't work correctly. This shouldn't be much
problem, since sh doesn't have them.
- Here documents in functions don't work. This is a problem with the
temp file allocation that requires more work to fix than I've gotten
around to doing. So avoid things like:
foo() {
cat <<- HereDoc
This is a test
HereDoc
}

I got the pd-ksh from John MacMillan after he indicated that he
had a version of it that had vi editing (I'd seen various versions
with emacs-editing, but none with vi).
It had a few bugs and areas which were not quite complete. I fixed
(or at least tried) to fix several; there are still some things
which I plan on doing (or at least looking into).
Bugs fixed (or at least abated):
vi-mode changes:
- Changed memcpy() to memmove(), which fixed the trashing of
the end of the edit buffer while inserting in the middle
of a line or with use of '#'
- using 'r' replacing the current character with ^@
- typing ctrl-c resulting in next command being garbled
- lack of support for '-' and '+' (pretty trivial)
- finish adding support for '*' (not entirely sure I'm freeing
malloc'ed memory correctly here, but I haven't had any problems)
- treats '_' as end of a word
general changes:
- reporting "not found" when a file actually doesn't have
the appropriate execute bit set (now says "cannot execute"
or "not found", as appropriate)
Still to do:
vi changes:
- fix ctrl-r (I've come up with a hack, but it involves
redrawing the screen a lot when it isn't necessary; I
really wouldn't consider this a fix)
- add support for 'v'
general changes:
- seems to be a memory leak when executing shells in the
current shell; repeatedly executing ". /etc/profile"
increased the size of the program as reported in the
"SZ" field of "ps -l"
- don't give a file its complete pathname in argv[0]; only
its filename (religious issue?)
- history recall should start at the previous command, not
the current one (typing "r r" causes an infinite loop)

Changes by Peter Collinson - Hillside Systems/BSDI - July 1992
a) Add select command - this cannot be ksh without that.
(It NEEDS typedefs too)
b) Remove all the bcopys from vi.c
add
#define memmove in sh.h for BSD systems
c) Add <Esc>* command to vi mode - expands to a list of files
using the menu printing routine
d) Add my version of history, that works much like the `proper' ksh
storing data in a file that is shared between different invocations
of the shell.
e) Add the ability to redirect to am expansion... ie
ls > o*
if o* is unique then it puts it into the file that matches
otherwise it puts it to a file called o*... this is current
behaviour.
f) Add alternations, from Csh.d) This is not part of ksh but is something
that csh users really miss from the Bourne shell derivatives. The idea
is that lists inside curly braces expand to arguments. ie.
exampl{a,b,c,d,e}
will expand to 5 arguments
exampla examplb examplc exampld example
Recursive lists are permitted.
g) Add suspend as a built-in alias.
h) Port to BSD/386 - add _POSIX_TERM and _BSDI as defines.

Public Domain Korn Shell
Version 4.9
PD KSH:
This is the latest version of the PD ksh (pdksh). It is not intended
to be the ultimate shell but rather a usable ksh work alike. For
those of us who have to work on multiple systems it is nice to have
the same user interface on all. I resisted moving to the ksh on a
System V machine where I worked, for nearly a year due to the lack of
a ksh on my Sun systems. When I first picked up the 3.2 PD KSH a
couple of years ago, it took only a few minutes to convert a C-shell
fan to a ksh fan :-) Pdksh is not 100% compatible with the ksh.
Having said that, I use it daily beside a real ksh88 and find them
virtually indistinguishable. With one exception - arrays! If some
one feels like adding arrays, I for one would appreciate it :-)
I only run this shell on sun's and BSD systems and only for
interactive use. I use it on sun4c, sun3, sun386 and 386bsd systems.
The shell itself has been compiled on the sun's both with and without
the POSIX/ANSI compatability libraries in ./std. I do not use ./std
for 386bsd and friends. See the file MACHINES for details of systems
that the shell has been built on.
I released version 4.0 of the shell (with the kind permission of
the previous maintainers and major contributors) to ensure that
it is available from usenet archive sites. Of course it remains
in the Public Domain. Equally obviously neither myself nor any
other contributors make any claims of suitability etc. Ie. NO
WARRANTY!!! If you make any changes and distribute them, please
leave your own finger prints in the source. Its bad enough
being flamed for my own bugs let alone anyone elses :-)
HISTORY:
This shell was written by Eric Gisin. It is based on Charles
Forsyth's public domain V7 shell, which he later contributed to
Minix. John R MacMillan picked up Eric Gisin's version after
Eric moved on to other projects (see ReadMe.jrm).
Since then there have been many contributors to this shell.
Most have left their fingerprints within the source and various
ReadMe.xxx and Changes.xxx files reflect their input.
This version is basically that known as Eric Gisin's version 3.3
alpha which I obtained indirectly from John R MacMillan who is
the most recent maintainer. This version has much improved
emacs-mode command line editing (my main contribution) plus
enough extra emacs-mode features to make it difficult to
distinguish from ksh88. Bug fixes from various contributors are
the only other changes from John MacMillan's version.
I have upped the version number for this release to distinguish
it from the original 3.3 version. This version is much improved
despite the small number of new features.
INSTALLATION:
The file INSTALL contains intructions for building and
installing the shell.
The original instructions indicated that a POSIX compliant
environment and possibly an ANSI compiler are required. I have
used both gcc and native Sun and the GreenHills ANSI compiler
without problems.
The POSIX/STDC compatability stuff in ./std seems to cause lots
of problems for some systems. This was at least in part because
I distributed it with half the librraies disabled :-), in any
case the shell itself in ./sh can now be compiled without any of
the ./std stuff which makes things much simpler on systems that
have a real POSIX environment.
Porting to new environemnts can be a real pain. I don't really
plan to make a huge effort in this area since I expect that this
shell will be mainly required on exotic or obscure systems (the
ones that the vendor does not provide a ksh for). Thus the
small "market" does not warrant a C-news or X11 style
portability effort. Of course if people send patches for
various systems I'm happy to try and integrate them.
ENVIRONMENT:
My main interest in this shell is for Sun workstations. Every
other UNIX system I use comes with a real ksh. Being a strictly
C-shell environment, some improved profile files are in order on
Sun's.
The etc directory contains a set of useful environment files.
These are the same files I use on several systems (many use a
real ksh):
./etc/profile
./etc/sys_config.sh
./etc/ksh.kshrc
The first one is obvious. The second, sys_config.sh is sourced
by /etc/profile and several other scripts. It is used to
determine the system type so that scripts like profile can be
used on multiple platforms.
The third one is also quite useful, add
. /etc/ksh.kshrc
to user's ~/.kshrc to simplify alias management.
BUGS:
Many folk have contributed to this shell.
I have attempted to credit (in sh/ChangeLog) the authors of bug
fixes received since the previous release.
There are surely still plenty of bugs to be found/fixed.
There is a template bug report in bug-report [borrowed from the
X11R5 mit tree], just fill in the blanks and mail to
pdksh-bug@zen.void.oz.au.
I hope you find this shell as useful as I do...

Quick installation notes for PD KornShell
PD KornShell can be installed on 4.2+ BSD systems, System V, and
POSIX-compatable systems. The makefiles all define _BSD, change
this to _SYSV, or _POSIX. The makefiles also contain CC=gcc,
delete this if you don't have GNU C. The ksh makefile also
contains some options, including JOBS (BSD/POSIX job control)
and EDIT (emacs command editing).
PD KornShell assumes you have standard C (ANSI) and POSIX header
files and functions. Since you probably don't, they are provided
in the "std" directory.
The Alpha test version will probably come as two tar files.
std.tar contains standard C and POSIX emulation and must be
extracted into a directory called std. ksh.tar contains the ksh
source and should be extracted into a directory called src or
ksh.
See std/ReadMe and install it. Only then can you make ksh in the
"src" directory.
To clear up questions about the origin of this shell, this shell
is NOT based on the "Minix shell". It is based on Charles
Forsyth's public domain V7 shell, which he later contributed to
Minix.
I have permission directly from Charles Forsyth to use his shell.
Eric Gisin, egisin@math.UWaterloo.CA (or Waterloo.EDU)
Things to do
- add sxt-based job control (see Brown's contribution on the Usenix 87 tape).
- add arrays and variable attributes.
- add MAILPATH and CDPATH.
- add vi editing mode (apparently someone has a PD version).
- add new features described in Korn's book.

HORIZONTAL SCROLLING
====================
I have migrated my 3.2 ksh edit.c mods into the 3.3 ksh
This file describes the mods in general and really only applies
(at this stage) to emacs-mode. I have not touched vi-mode apart
from making it use pprompt() so that '!' is correctly expanded
as in emacs-mode.
I would prefer to see both vi.c and emacs.c use a common set of
primatives in edit.c - but that looks like a lot of work.
Basically my mods affect the functions that move the cursor
about and redraw the edit line.
The input buffer "buf" is pointed to by "xbuf" and its end is
pointed to by "xend". The current position in "xbuf" and end of
the edit line are pointed to by "xcp" and "xep" respectively.
I have added "xbp" which points to the start of a display window
within "xbuf".
[A] starting position
buf
|<-------- $COLUMNS --------->|
| |<---- x_displen ------->|
| PS1|
+==========+==============--------+.......+
|\ \ \ \
xbuf xbp xcp xep xend
[B] scrolled
buf
| |<----- COLUMNS -------->|
| |<----- x_displen ------>|
|
+-----------+==========+==============--------+.......+
\ \ \ \ \
xbuf xbp xcp xep xend
In the above -------- represents the current edit line while
===== represents that portion which is visible on the screen.
Note that initially xbp == xbuf and PS1 is displayed.
PS1 uses some of the screen width and thus "x_displen" is less
than $COLUMNS.
Any time that "xcp" moves outside the region bounded by "xbp"
and "xbp" + "x_displen", the function x_adjust() is called to
relocate "xbp" appropriately and redraw the line.
Excessive I/O is avoided where possible. x_goto() for instance
calculates whether the destination is outside the visible
region, and if so simply adjusts "xcp" and calls x_adjust()
directly. Normally though x_adjust() is called from x_putc().
The above mechanism has be updated to use a function x_lastcp()
that returns a pointer that accurately reflects the last
visible char in the edit buffer. That is a more accurate
version of xbp + x_displen which does not account for TABS.
Other changes
=============
I have also added some emacs mode functions.
M-[0-9]
Set a numeric arg (positive only).
Used by all word related commands.
M-_
M-.
Retrieve word from previous command (default is last
word). Use M-[1-9] to select word.
M-u
M-l
M-c
UPPER,lower,Capitalize word.
Commands like delete-word now push the deleted text so that it
may be yanked back into place.
BUGS?
=====
There are bound to be some. Please report same to me:

BUILDING THE PD KSH
===================
As usual, there are differences between BSD and System V
versions. Ideally, all you have to do is edit the Makefile in
this directory to set the CONFIG macro to the appropriate value.
(Actually, you may wish to change the CONFIG macro in all
Makefiles; if you always invoke make(1) from here, CONFIG will
be passed down, but if you invoke make(1) from a subdirectory
you'll want the appropriate definition in that Makefile.)
Of course it's not quite that simple. You may, however, take
solace in the knowledge that it used to be worse.
The Compatibility Libraries
---------------------------
Eric Gisin wrote this shell using ANSI C and POSIX as
portability guidlines. Realizing that nobody had a POSIX
system and almost no one had an ANSI C environment, he provided
minimal compatibility libraries.
There are two libraries, one for POSIX (libposix.a) and one for
ANSI C (libstdc.a).
Libposix.a is pretty simple. Nothing in it has ever broken on
me, so I'd just leave it. It provides a version of dup2() for
System V systems.
Libstdc.a is a bit hairy. I recommend looking at the routines
provided and, and editing the std/stdc Makefile and only
including objects that have routines your system libc.a is
lacking. Various of the provided routines are just plain
flaky, but only when they're not really needed. The other
hairy thing he does is craft an ANSI stdio.h from the system
supplied one and one of his own. Again, it's better than it
used to be, but it's still a hack, and you may have to modify
it by hand.
You will also need a POSIX compatible set of directory reading
routines. System V.3 systems have this in libc.a. The
std/posix directory provides a something for BSD systems. I
use a slightly modified version of Doug Gwyn's PD version.
(The ``slightly modified'' is to work around a bug in Gwyn's version.
The POSIX routines are documented as returning failure if the file for
opendir(3) is not a directory. Gwyn attempts to open(2) the file, and
then stats it to see if the file is a directory. However, if the file
is a special file, and the open(2) doesn't return, you're screwed. My
change was to open the file with the O_NDELAY flag, but Gwyn didn't
feel this was portable (true, but I only do it where it works) and
that stat-ing before the open would be too slow (true). The upshot is
if you use his routines unmodified, don't ever do an "ls -l /dev/*/*".)
The Shell Source
----------------
The source for the shell itself is in the sh directory. There you
will want to edit config.h to determine the configuration options. Vi
mode is in kind of rough shape, but does work. DIRSTACK routines
aren't implemented yet, so again, why bother. SWTCH is a bit arcane,
but it you use shl(1) and you define EMACS or VI you want to define
this. JOBS is really only useful on BSD systems. It might work on
systems that have POSIX job control, but I wouldn't bet on it.
SHARPBANG is only useful on systems where the exec() family don't
honour the #!/prog/path convention.
This is where the shell gets built so you may wish to change
the OTHERLIBS macro in the Makefile to point to your POSIX
directory routines, or to use -lc_s, or whatever.
Miscellaneous
-------------
The Makefiles that actually compile things use the macro
CCOPTS, so you can change it in individual Makefiles or specify
it on the command line, eg. "make CCOPTS=-O OTHERLIBS=-lc_s".
LDOPTS is used in the Makefile where the ksh is actually built.
The very first time on a new system, do a "make clobber"
Good luck.
Documentation
-------------
The ksh.1 is a man page for the PD ksh, although it lags
somewhat behind the code. You get what you pay for.
The ksh88.1 is a man page for AT&T's ksh88 (the latest version)
provided for comparison.
History
-------
Much of the shell was written by Eric Gisin at the University
of Waterloo, using some pieces of other stuff, notably Charles
Forsythe's V7 shell, and some enhancements from the BRL shell.
He placed it (in a alpha test state) into the public domain
while I was at UW. I snarfed a copy, and got it running on my
UNIXpc, and later some machines at work. I sent Gisin some bug
reports, but he seems to have lost interest in the project.
This may be because he now does some work for MKS, who produce a
commercial version of the ksh for MS-DOS machines, so there may
be a conflict of interest.
So I gave up on getting future versions, and adopted it. I've
made some enhancements, and quite a few bug fixes, and various
people at work have contributed as well. It remains in the
public domain, although I imagine the people involved would
appreciate leaving their names attached (I'm exempt; I haven't
actually included my name anywhere but here).
The README in the sh directory is Gisin's, and tells a bit of
the story from his point of view. Note that his compilation
instructions don't really apply anymore.

Version 5.2.6
1. The bug where hereis documents would leave temporary files behind has
been fixed.
2. Changed extension search order to place .exe files ahead of files with
no extension. This permits the gcc option -Zexe to work properly,
however it causes some limitations. Should this be a problem then I will
have to detect and ignore zero length files without an extension as a
special case for gcc. I would prefer not to do this.
3. Increased the number of file descriptors available to 40. This corrects
a problem that showed up on some warp connect systems.
4. Allowed any extension to be used for a script so long as the user
explicitly types it in.
Version 5.2.4
1. You can now open multiple files in a script, i.e. exec works. Some
better checking could still be done.
2. A bug in reading input files where data was getting shifted around
has been fixed. (forced binary mode to emx a number of places for input.)
3. Directories with same name as executables will no longer cause an error.
4. OS2 cmd processing of extproc header line only passes the file name
to the spawned process instead of the full pathname. This is a bug
in os2 IMHO since if you explicitely want a certain path for the
command you cannot guarantee it. A change was made to search the
path within ksh to permit this processing to work. Note that the
copy ksh finds might not be the one you wanted but at least you can
copy your cmd files around without having to modify them. A side
effect of this change is that typing: "ksh whatis" will now search
your path as well which does change the standard behavior of ksh.
5. #! processing will now search for the shell using the explicit path
and if not found then it will use the path variable.
Most of you won't notice any difference since the shell will still
be found but if you needed a particular one then this can be done.
Note that if you only want a particular pathname use "\"'s in the path.
6. Ksh will now honor the advertised EXECSHELL variable if it is set
instead of OS2_SHELL as the shell to be used if there is no
#! or extproc line in the file. The difference is EXECSHELL will not
have any options supplied while OS2_SHELL will automatically get
/c and the pathname will have '\' as the directory separator.
OS2_SHELL will still be used if EXECSHELL is not set.
7. A new option to print, -f, has been added for os2 users. It will
force forward slashes. It is useful when trying to massage an
environmental variable containing backslashes using something like
sed which always interpretes backslashes as escapes. There is
and example of this in the new kshrc.ksh that I have included.
8. Working with os2 variables can be a pain try to escape all of the ';'s
so I have supplied some new functions in the kshrc.ksh. Please
checkout add_path, pre_path, and del_path. These functions will
append a path, prepend a path, or delete a path from the variable
you specify, PATH by default. These are modification of the
samples shipped with the unix pdksh startup files.
9. The echo output and other outputs from ksh now use forward slashes
and in general forward slashes will be seen more often than before.
Backslashes will still be accepted on input and command line
completion but it was too painful to try and preserve the os2 look
for output and permit Unix scripts to work. If you prefer the
old method change the variable DIRSEP in sh.h and rebuild.
10. A bug requiring all command extensions to be in lower case was
fixed. This showed up most often in the setting of OS2_SHELL.
11. os2/configure will now set up to build either ksh or sh.
Version 5.2.2
o OS2 executable can be built directly from original sources! No patches
required. Just unload, cd to source directory, run os2\configure, and
then make (v3.73 minimum), nmake, or dmake.
o Built on emx09a. (513 was built on 08.)
o Now uses full signal processing from emx. Previous version used fake
signals. Better and more accurate signal status.
o TMPDIR variable can now point to a another drive. Which can be a FAT
drive.
o Improved case folding in vi mode for file name matches.
o Vi mode can now use cursor keys if desired. (Like emacs mode)
o Both vi and emacs mode now get a set of default stty settings. ^C
and ^U should now work during command line editing.
o #!/bin/sh and similar lines at the top of scripts are now stripped
of pathname prefixes permitting use of standard OS2 search paths.
This should permit better shell script portability.
o case statement variable usage is now case sensitive. Also applies
to several other variable constructions.
o Now accepts .sh as an executable extension.
o All commands that start a new window are automatically backgrounded.
o ksh can usually be made to grok gnu configure scripts but the results
are still very script dependant. See the readme.os2 for details.
Version 5.1.3
This was the original version 5 release based on an earlier port of
4.9 by Kai Rommel.

OS/2 port of pdksh version 5
June, 1996
Introduction
This document is intended to define the specific features and
differences in the os/2 port of pdksh. For general features and
descriptions of pdksh itself please refer to the standard pdksh README
or the man page. In general the port has tried to maintain as many of
the standard ksh features as possible. For installation details and
an introduction to ksh please read the README.1st file shipped in the
run time zip package for os2.
A default build of pdksh, called ksh.exe, is included in the os2
run time package. This version was built using the emx environment and
therefore requires that an emx run time package 0.9b or later be
installed on the system. This is not normally a problem since you
probably already installed it for 'ls' and other Unix commands from
the file gnufutil.zip. (If you haven't install gnufutil.zip you may
want to consider it.)
Building KSH.EXE
If you would rather build your own, you should obtain the sources from
ftp.cs.mun.ca in the directory pub/pdksh. You will need a copy of tar
and gunzip to unload the archive and install on an hpfs partition. Change
to the source directory and run the script os2\configure.cmd. (If you
prefer you can copy configure.cmd to the source directory.) This will
prepare the build environment so that your version of make can be used
to build the executable. Note that configure.cmd is still under
construction and you may need to make changes to the Makefile and to
config.h to match your specific needs. Copies of all of these files
will be placed into the source directory. In addition you may want to
make changes to config.h to define your particular preferences.
Configure.cmd for os2 support these optional options and arguments:
/h | /? | -h Print a usage message and exit.
/v | -v Print verbose output during configure
/d | -d build a debug version with symbols (for gcc)
sh build sh rather than ksh
Any configuration other that the default requires that sed be in your
search path. You should always get a copy of the latest pre-built version
of ksh as well since the file os2bugs may contain some last minute fixes
that were too late to include in the formal release, and you may find some
other updates. In addition the run time version supplies a couple of
sample icons for use with ksh.
At this point you can use your favorite make command to build the
executable. Pdksh is known to work with nmake and dmake, gnu make requires
at least version 3.7.3 and is the only one that will automatically make the
man page. You can manually run mkman after starting your new copy of ksh,
'ksh mkman ksh|sh ksh.man'. (A prebuilt sh and expanded cat version of
ksh.1 is included in the rt package.)
There is a built in check routine that is part of the makefile. Type
'make check' to run it. This routine needs a copy of perl on your
machine in order to support the test harness used to test the build. I
have built the infrastructure into the port to support this checking but
have not been able to get it all to run correctly yet. The problem is
because of a bug in the os2 port of ksh. To check the build without using
perl, run the command: 'ksh Bugs ksh'. This will use the older checking
facility. You should run this if you make any changes to the source to
insure that you haven't broken something crucial. Run make check on an
unmodified version first so that you will know what to expect. If you
want to get the perl version running please contact me for information.
KSH 5 VERSUS KSH 4.9
The KSH version 5 effort is being spearheaded by Michael Rendell. Michael
took over the effort from Simon J. Gerraty who maintained the version 4
code. While the version 4 code was a good implementation of ksh
version 5 strives to continue the conformance to the actual posix
definitions and to AT&T ksh.
For my version 5 port to os/2, I originally started with the 4.9 os/2
changes and applied them to the new version. Subsequently many changes
have been made so that there is little resemblance to that version.
One of my goals for version 5 is to make ksh not only and interactive
shell, but one that can run some limited Unix(tm) shell scripts as well.
Generally the two shells behave the same. Version 5 has no logout script
(This can be set up using a trap in your profile.ksh file if desired.) and
the option 'hashall' has been replaced with 'trackall'. (To see all of the
options use the command 'set -o'.) In addition the prompt has been changed
to conform with the at&t ksh shell instead of the csh like implemetation of
version 4. The '!' sign is used for the history number and $variable
substitutions can be used in the prompt. The commands generally behave more
consistently. For example bind now goes to standard out so it can be
redirected or piped. Arrays are now implemented as are almost all AT&T ksh
features plus a few more. The os/2 port provides file name completion that
is not case sensitive. The startup file kshrc.ksh is still supported, but
the way it works is slightly different.
OS2 IMPLEMENTATION VS. UNIX
The original OS/2 port was done by Kai Uwe Rommel. I have re-implemented
his ideas in this os/2 version. The os/2 version of ksh has been modified
to accept the standard os/2 conventions. Drive designations a:, etc., are
accepted and path separators in variables have been changed to ';'. In
addition either '/' or '\' can be used as a directory separator. The bind
command in emacs mode has been enhanced to accept function key and alt key
bindings. (To see what the alt key binding should be, use ^Q followed by
the key you are interested in. Replace the ^ alpha you see with ^0, typed
as two characters, in the bind command.) The cursor keys have been
implemented for command history for both emacs mode and vi insert mode.
Standard default stty settings are implemented for both modes as well.
A os2 only print option, -f, can be used to force forward slashes in its
argument. This can be used to switch a variable containing '\' to
output '/' in a pipe to a unix command that doesn't like '\' as a path
separator, such as sed.
/ vs. \ processing
The remapping of certain keys can lead to some confusion for Unix and OS/2
users. The '\' key has a different meaning in Unix where it is used
to escape a special meaning for the character following it or in the
case of the echo (typeset) command it provides special meanings to
certain characters. At the end of a line the '\' is used to escape the
line feed permitting a command to extend to multiple lines. In OS/2
this key is generally the directory name separator. To provide for
both functions in the OS/2 pdksh the '\' is defined to be a directory
separator in any pathname specification and will keep its escape
meaning when it is followed by any non-alphanumeric character. The
echo command retains its special interpretation of '\' and will, for
example, interpret \t as a tab when printing. This can be
disconcerting when you echo the variable that you just set to c:\tmp.
If you want to use echo on a variable with pathnames in it you should
either use uppercase names or a '/' as a separator. Another choice is
to alias echo to 'print -r' or perhaps 'echo -E'. This will disable
the special interpretaions. You could even use the new 'print -f' to
force any '\' to switch to '/', but this is less portable. If you have
loaded the printenv command it can be used to look at variables.
Unix uses '/' as a directory separator and the OS/2 implementation
permits and in some cases prefers this use as well. Generally you
can freely mix '/' and '\' characters in a pathname. However, 'cd \'
will not complete since '\' will escape the new line command and you
will get the secondary prompt. Just enter a / and the command will
complete. For many standard os/2 commands the '/' is used to indicate an
option and may want a '\' as a path separator. These will still work and
be correctly interpreted with pdksh as long as a '/' is not attached
directly to the command name. Just be sure and enter the syntax needed
by the command you are trying to execute.
While backslash processing is usually correct and automatic there are times
when it doesn't do what you might expect. For example ls \tmp\*.exe might
surprise you. In this case the '\' will be interpreted as an escape for
the '*' character. You may need quotes or several backslashes to get what
you want. Beginning with 5.2.4 the output of ksh favors '/' for any
generated pathnames. This is intended to make script processing for
unix scripts easier. Unfortunately, this may make interactive use for
os2 users that prefer the '\' key a little less desirable. Should you
prefer the earlier convention then you can rebuild the executable from
the sources. Only one change in sh.h, DIRSEP, controls this behavior.
; vs. : processing
Another conflict is the use of ':' and ';'. Unix uses ':' to separate
entries in variable assignment and ';' to indicate multiple commands
on the same line. OS/2 uses the ';' to separate entries in a variable.
This could lead to problems when making an assignment to a variable in
pdksh. You will need to escape the ';' in OS/2 to prevent the shell
from interpreting it as the end of the command. Either surround the
assignment command with quotes or use '\;'. Note that since a ';' is
not a valid filename or pathname character the '\' will be correctly
interpreted as an escape character.
Since having to escape the ';' character can be a pain when changing
environmental variables containing a list of paths there are some functions
defined in the sample kshrc.ksh file to ease this task. There are three
functions; add_path, pre_path, and del_path that can be used to append a
path, prepend a path or delete a path from any environmental variable (PATH
by default). If you needed to add a path to /emx/bin you might do "add_path
e:\emx\bin" for example, or perhaps "add_path e:\emx\book BOOKSHELF" to add
some books to the bookshelf. Note that you will need a copy of sed in your
search path to use the del_path function.
In OS/2 the ':' is used to separate the drive letter from the rest of
the pathname. This usage had been preserved in pdksh. You can imbed
the drive letter as needed in pathnames. In addition pdksh preserves
the notion of separate contexts for each drive. To change drives you
would use the cd command. "cd A:/" would change to the root on drive
A while "cd C:." would change to whatever was current context on drive
C. Some aliases are defined in the sample kshrc.ksh to permit the
usual A: to automatically do a change directory to the A drive.
Wildcard Processing
OS/2 and pdksh have similar notions about wildcard characters '*' and
'?' except that pdksh handles the expansion of these wildcard within
the shell and then passes the answer as a list to the application. If
the application needs to see the wildcard character then you must
escape it from the shell. Note that pdksh knows about other wildcard
techniques as well. Please see the man page.
Background Processing
Do to some limitations in the os2 fork process and other differences
between os2 and unix it is not possible to support back-grounding from
pdksh of commands that begin a new window. For this reason I have
automatically backgrounded all such tasks when they are started. This
will permit the os2 ksh to serve as a command line launch mechanism for
dos, full screen, and pm applications. (Note that currently ksh can only
launch an application of the same type (windowed, or fullscreen) that
ksh itself is unless you use the 'start' alias.
There is a 'start' alias defined in the sample kshrc.ksh file that can
be used to start normal command line commands in a new window. For example
you could say "start ksh" to start a copy of ksh itself in a new window.
Since it is a new window it will automatically return control to the existing
copy of ksh. Note that the start alias uses the os2 start command so
you could supply it with any standard start option such as /FS to force
a full screen copy. Please check your os2 command reference manual for
further information on start.
PDKSH, OS/2 and the ENVIRONMENT.
The environment in OS/2 and Unix are quite different. For one thing
you don't actually login to your machine in OS/2 and your initial
environment is established by your CONFIG.SYS file. The Shell will use
the variables that were set in CONFIG.SYS and you should really
consider assigning TMPDIR and HOME for use by pdksh. It will also use
ENV as a variable that names a startup file that will run each time
the shell is started, even if a script is started. This start up file
is located in your home directory. For compatability with 4.9 this
shell will also automatically use a startup shell kshrc.ksh if it
finds one in your home directory, is started interactively, and $ENV
is not set.
The variable OS2_SHELL should point to cmd.exe or a fully compatible
version and will be used as the shell of choice for any scripts that you
write that do not contain the #! or extproc information in the top line
of the script. If you prefer you can set the variable EXECSHELL to a
shell to be used instead of OS2_SHELL. The use of OS2_SHELL assumes that
the shell requires the /c option and that the shell needs all pathnames
separated with '\'. Setting EXECSHELL will disable both of these
assumptions.
A special feature is the support of the -l, login option. If this option is
entered when starting ksh then the shell will execute a loginfile called
profile.ksh if located in $INIT/etc, c:/usr/etc, or your home. If you are
using this shell as your primary shell you may wish to change the settings
in your os2 command shell notebook to call ksh.exe -l. I would not
recommend changing the default shell in config.sys.
Should you destroy your PATH variable try 'unset PATH'. A default
path may get you going again. In addition pdksh for OS/2 always uses
commands from current context first in the search path even if it is
not explicitly set. By default c: drive is used when no variables
are set. Specifically c:/usr/bin and c:/usr/etc can be used as defaults
various places in ksh. If you build your own version then this can be
changed.
Generally all of the environmental variables described in the man page will
work in OS2 so long as the tools in use understand them in the same way
as Unix would.
Using KSH
The shell itself can be called any name you wish. Good names include
pdksh.exe, ksh.exe, sh.exe. You can build two completely different
shells using the options file. A full blown Korn shell can be built
or a complete subset that behaves very much like a Bourne shell. The
smaller version is excellent for script support. In the run time
release I have provided the full shell under the name ksh.exe and the
smaller version under the name sh.exe. Be careful with names like
rksh.exe or you could end up with a restricted shell that can't do
everything.
In Unix an executable can be tagged with an attribute to
make it known to the system as an executable. In OS/2 this is done
with an extension. This shell knows all of the standard OS/2
extensions plus .ksh and .sh. (Yes it can run dos commands and OS/2 command
files as well.) The .ksh or .sh extension tells the shell that this is an
executable shell script. The current version will also treat a file
without an extension as an executable in the style of Unix. Scripts need not
necessarily be a ksh shell scripts however. The standard Unix #! line at
the top of the file determines the actual shell that will be used to run
the script. A feature in this release is that any Unix absolute
pathnames will be tried and, if they fail a second try will be made by
stripping the path from the #! line since Unix style paths are unlikely
to match os2 usage. Your standard PATH search path will be used.
Should the same filename with a different extension exist in the same
directory pdksh will use the extension typed in by the user or if
no extension is entered then the search order is, .ksh, .exe, no extension,
.sh, .cmd, .com, .bat. This search order permits ksh scripts to be used to
modify binary executable behavior while allowing the -Zexe option for emx
gcc. . Note that if you explicitly type the extension yourself then any
extension can be used so long as the #! processing line is at the top of
the file to let pdksh know what to do.
The sample kshrc.ksh file that comes with the distribution can be used as
an example that shows you how to create aliases that will simulate the
standard OS/2 commands. This means you can still use copy, dir, and del if
you want to. Keyboard bindings supplied will still provide the command
stack and suddenly you also have command line completion and alias
capability. To get the most from the shell you will probably want the set
of Unix commands developed by the Gnu team and ported to os2. You will
most certainly need them or a similar set if you want to run any Unix
scripts. A few functions are also provided in the sample kshrc.ksh file to
demonstrate the power of functions and to ease common tasks.
Unix file systems are case sensitive and ksh generally expects this also.
This means that internal commands as well as aliases are case sensitive.
You can use this to your advantage. For example you might want to run a dos
shell only to find out that 'command' is captured as an internal command by
ksh. Try 'COMMAND' or even 'Command' and you will get what you wanted.
The file name completion and wild card expansion has been modified for os2
to permit it to ignore case.
Working with Editing Modes
As delivered ksh for os2 supports three different editing modes to use
with the command line. By default the editing mode is the same as that
used in cmd.exe in that F1, F2, and F3 can be used to edit the previous
command. Left and right cursor keys can also be used to edit the command.
Support for this comes directly from the emx layer. The history mechanism
is supported in this mode but you will not be able to scroll trhough
history from the command line. Pdksh commands exist to display and edit
history and the EDITOR environmental variable can be set to specify the
editor you want. Two other mutually exclusive editing modes exist as well.
The sample kshrc.ksh file turns on emacs editing mode. In this mode
pdksh emulates the commands and keyboard binding present in emacs. The
keyboard binding is fully customizable by the user using the bind command.
For os2 the default build includes support of the cursor keys to edit
both current and previous commands. The sample kshrc.ksh file includes
some further mapping as examples of keyboard binding. The bind -m
command can be used to define special macro commands. Note that in emacs
the ESC key following by a letter key is usually synonymous with holding
down the ALT key and pressing a letter key. In the current os2 implementation
these keys are not tied together so they could be programmed independantly
although this could be confusing for the user. This may change in the
future.
Issuing the command 'set -o vi' turns on vi mode. This mode emulates the
keyboard binding from the vi editor. In addition using the tab key for
command line completion is separately programmable using the set command.
For os2 the cursor keys are also set up to work from within insert mode to
allow editing of both the current and previous commands without ever
leaving insert mode. The Esc Shft-A sequence can be used to jump to the end
of the line allowing you to append new information to the line. CTRL-X,
CTRL-E and CTRL-F permit command line completion within insert mode. Thus
you can use vi mode without ever having to learn traditional vi commands.
SHELL SCRIPT PROGRAMMING
One of my goals in porting this shell was to be able to do shell level
script programming and to run Unix shell scripts with minimal modification.
The first goal is easy and fully functional in this release. You can write
shell scripts for this or other shells. The name of the shell you want to
run the script is entered in the first line of the script itself after a
'#!' sequence. If you only enter the name of the command then pdksh will
use your search path to find the shell. This is the recommended approach,
however absolute paths of the form /bin/ etc. will be stripped
automatically if needed to permit running Unix scripts unmodified. To write
portable scripts use the 'uname' command from Gnu to set a variable that
can be checked for specialized approaches. As a special case absoulte
paths using '\' will not be stripped and an error will be generated if
the command is not found at the exact path specified.
It is even possible to use ksh as a scripting language when your main
shell is a standard OS/2 shell. To do this you would write your ksh
script as usual except that the first line in the script should read
'extproc ksh'. The script should be named with a '.cmd' extension so
that the OS/2 shell can find it. When the cmd.exe finds this line in
the file it will call ksh to process the script for you. A script
that is written this way can also be called directly from ksh. As a
matter of fact you could use this technique entirely for script
creation and name all your scripts with the .cmd extension. Pdksh
will honor 'extproc' exactly like the standard Unix '#!' processing.
Unlike Unix #! processing the OS2 cmd processing of an extproc header line
only passes the file name to the spawned process instead of the full
pathname. This is a bug in os2 IMHO since if you explicitely want a
certain path for the command you cannot guarantee it. The workaround was to
put the path in the extproc line and then shift the extra filename off the
argument list. For example my whatis.cmd file used to start like this.
extproc ksh c:/usr/bin/whatis.cmd
shift
You can still do this, but ksh will also search the path to find a copy
of the command, so this is no longer required. Of course, the copy that ksh
finds might not be the one you wanted but at least you can copy your cmd
files around without having to modify them. A side effect of this change
is that typing: "ksh whatis" will now search your path as well which does
change the standard behavior of ksh which some might construe as a feature!
The second goal of running Unix scripts with little or no modification is
much more difficult to achieve. Unix makes many assumptions about how the
system is set up which makes fully portable scripts difficult to accomplish
without the knowledge of the script internals. Many script assume the
presense of /dev/null and /tmp. (The emx layer provides an automatic map
for shell references to /dev/null and /dev/tty as of the 0.9a version and
pdksh also maps /dev/null to nul for the cases where emx doesn't see it
unless a /dev/null is present.) Some scripts assume /bin and certain
commands within /bin (usually cp and sh). Until I can figure out how to
make this more transparent you can simply make these directories on the
drive that you intend to run the script on. (Of course, you could also
modify the script.) Some scripts reset the PATH variable near the beginning
of the script. While you could copy a whole set of commands it is probably
easier to modify the script or use tvfs (more about tvfs later.) Another
standard "trick" in Bourne shell script programming is to modify IFS to
include a colon and then use the set command to parse a variable by setting
$1, $2, etc. In OS/2 this would need to be a ';'. For now you will have to
hand modify the script.
The latest release of ksh for os2 now supports multiple open files
using standard pdksh syntax. Note that error checking may not be
as complete as standard pdksh for some of this usage.
Of course Unix scripts expect the presence of Unix commands. You will
need to install a set of Unix utilities, Unix text processing
commands, and probably sed and a version of awk. I have created a
c:/usr directory on my system for Unix stuff. I have /usr/bin,
/usr/man, /usr/etc, /usr/home, and /usr/local. You could establish
even more, or perhaps less, Unix conformance. You will also need a ps
command. I use procs.exe which I renamed to ps.exe. Kill is a ksh
builtin.
RUNNING UNIX GNU CONFIGURE SCRIPTS.
A lot of people would like to use pdksh to permit them to run the
gnu automatic configure scripts. I am pleased to report that this
is possible using pdksh. However, I can't guarantee that the results
will match the true configuration for os2 since this is dependant on
the way the individual configure scripts are written.
To set up to run configure scripts you will need to have a copy of pdksh
called sh.exe somewhere in your path and, of course, you should be
running within a pdksh shell. One of the very early things done
by most configure scripts is to figure out the compiler. This will fail
since it depends on setting the IFS (see the above discussion). To
workaround this problem simply set CC to the compiler you want to use
prior to running the script. For example to use gcc: 'export CC=gcc'.
Most configure scripts couldn't figure out the names of os2 compilers
anyway. Now you should be able to simply type 'configure' and watch it
work. At some point the configure script will build a config.status
script to perform the final step. If this is not run using 'sh -c
config.status' or some such it will fail since .status is not an os2
legal executable suffix. You can run it manually however by typing
'ksh config.status'. If you have problems you should inspect the
config.status script and fix it as required. Using ksh -x config.status
will echo the lines as they are executed which should aid in debug.
Many configure scripts actually build and execute programs to test
for certain features. In OS2 using emx, the final link step must have
the .exe extension tied to the executable name or the linker will not
link correctly. You will need to modify the configure script to
insure the correct executable name. Once this is built it can be
renamed to a name without an extension if ksh is being used to run it.
A line similar to the following may work for you if you are using 2.0:
ac_link='${CC-cc} -o conftest.exe $CFLAGS $CPPFLAGS $LDFLAGS \
conftest.$ac_ext $LIBS && mv conftest.exe conftest'
This trick takes advantage of ksh's ability to run a command without an
extension. Even with these changes you may still find that configure does
not correctly identify some os2 features. I would recommend that the
config.cache file be edited as required or the resulting config.h file.
Another trick is to use the -Zexe option to gcc. This builds a zero length
file without an extension and the real executable with the extension .exe.
Makefiles and some configure scripts may be fooled by this behavior.
TVFS
An IBM employee written program called tvfs, toronto virtual file system,
can be downloaded from most os2 ftp sites and from IBM ftp sites. This
program permits you to simulate a Unix like file system that can span
physical drives and even network drives. Using tvfs you cd once into the
drive letter designated as the tvfs drive and from then on you can
reference all of your drives and directories by only using Unix style
pathnames if you wish. Even a limited form of symbolic links can be set
up on this drive. This can be a great aid in running Unix scripts and
makefiles as well as configure scripts.
WORK IN PROGRESS
There is still much to do and this project will probably never be complete.
The configure.cmd file needs work as does the Makefile. Please let me know
if you get this to compile using a C compiler other than gcc. The standard
defaults work in the Makefile but many other things are not implemented.
And of course there are bugs to fix and enhancements to be made. Check the
file os2bugs in the run time release for the latest information on bugs.
Please let me know if you like this port, have found a porting bug,
have fixed a bug, or have coded a spiffy enhancement. Michael Rendell
should be consulted for general pdksh items and is now actually
maintaining and enhancing all of the code. Please check the standard
README for more information and also the file os2bugs for current known
problems and limitations. I can be reached at daled@cadence.com.
Note that this is a home brew project and is in no way related to my
employment.

Bugs and Limitations
1/99
1. Some of the makefile targets are not yet working. Those known to
work include all, uninstall,ksh, config.h, makefile,
debugtools (only check-fd and check-sigs.), test, clean, & distclean.
You need to run ksh Bugs ksh, or sh Bugs sh as appropriate.
2. You cannot start a full screen session from the windowed ksh command line.
3. Job control is not working and may never work in os/2 (no sigstp,
sigcont, etc).
4. ls [B]* fails even when a file Bozo exists. ls [b]* will work
due to case folding. The bug is in the way case folding is managed.
ls b* or ls B* will work as expected.
5. regress.t:regression-13 test fails. I do not understand why it can
work on *nix. In fact cat does not get SIGPIPE, but gets write failure.

/* NAME:
* sigact.c - fake sigaction(2)
*
* SYNOPSIS:
* #include "sigact.h"
*
* int sigaction(int sig, struct sigaction *act,
* struct sigaction *oact);
* int sigaddset(sigset_t *mask, int sig);
* int sigdelset(sigset_t *mask, int sig);
* int sigemptyset(sigset_t *mask);
* int sigfillset(sigset_t *mask);
* int sigismember(sigset_t *mask, int sig);
* int sigpending(sigset_t *set);
* int sigprocmask(int how, sigset_t *set, sigset_t *oset);
* int sigsuspend(sigset_t *mask);
*
* RETSIGTYPE (*Signal(int sig, RETSIGTYPE (*disp)(int)))(int);
*
* DESCRIPTION:
* This is a fake sigaction implementation. It uses
* sigsetmask(2) et al or sigset(2) and friends if
* available, otherwise it just uses signal(2). If it
* thinks sigaction(2) really exists it compiles to "almost"
* nothing.
*
* In any case it provides a Signal() function that is
* implemented in terms of sigaction().
* If not using signal(2) as part of the underlying
* implementation (USE_SIGNAL or USE_SIGMASK), and
* NO_SIGNAL is not defined, it also provides a signal()
* function that calls Signal().
*
* The need for all this mucking about is the problems
* caused by mixing various signal handling mechanisms in
* the one process. This module allows for a consistent
* POSIX compliant interface to whatever is actually
* available.
*
* sigaction() allows the caller to examine and/or set the
* action to be associated with a given signal. "act" and
* "oact" are pointers to 'sigaction structs':
*.nf
*
* struct sigaction
* {
* RETSIGTYPE (*sa_handler)();
* sigset_t sa_mask;
* int sa_flags;
* };
*.fi
*
* RETSIGTYPE is normally 'void' in the POSIX implementation
* and for most current systems. On some older UNIX
* systems, signal handlers do not return 'void', so
* this implementation keeps 'sa_handler' inline with the
* hosts normal signal handling conventions.
* 'sa_mask' controls which signals will be blocked while
* the selected signal handler is active. It is not used
* in this implementation.
* 'sa_flags' controls various semantics such as whether
* system calls should be automagically restarted
* (SA_RESTART) etc. It is not used in this
* implementation.
* Either "act" or "oact" may be NULL in which case the
* appropriate operation is skipped.
*
* sigaddset() adds "sig" to the sigset_t pointed to by "mask".
*
* sigdelset() removes "sig" from the sigset_t pointed to
* by "mask".
*
* sigemptyset() makes the sigset_t pointed to by "mask" empty.
*
* sigfillset() makes the sigset_t pointed to by "mask"
* full ie. match all signals.
*
* sigismember() returns true if "sig" is found in "*mask".
*
* sigpending() is supposed to return "set" loaded with the
* set of signals that are blocked and pending for the
* calling process. It does nothing in this impementation.
*
* sigprocmask() is used to examine and/or change the
* signal mask for the calling process. Either "set" or
* "oset" may be NULL in which case the appropriate
* operation is skipped. "how" may be one of SIG_BLOCK,
* SIG_UNBLOCK or SIG_SETMASK. If this package is built
* with USE_SIGNAL, then this routine achieves nothing.
*
* sigsuspend() sets the signal mask to "*mask" and waits
* for a signal to be delivered after which the previous
* mask is restored.
*
*
* RETURN VALUE:
* 0==success, -1==failure
*
* BUGS:
* Since we fake most of this, don't expect fancy usage to
* work.

/* Changes to sigact.c for pdksh, Michael Rendell <michael@cs.mun.ca>:
* - sigsuspend(): pass *mask to bsd4.2 sigpause instead of mask.
* - changed SIG_HDLR to RETSIGTYPE for use with GNU autoconf
* - added and used RETSIGVAL
* - include sh.h instead of signal.h (to get *_SIGNALS macros)
* - changed if !SA_NOCLDSTOP ... to USE_FAKE_SIGACT to avoid confusion
* - set the USE_* defines using the *_SIGNALS defines from autoconf
* - sigaction(): if using BSD signals, use sigvec() (used to use
* signal()) and set the SV_INTERRUPT flag (POSIX says syscalls
* are interrupted and pdksh needs this behaviour).
* - define IS_KSH before including anything; ifdef out routines
* not used in ksh if IS_KSH is defined (same in sigact.h).
* - use ARGS() instead of __P()
* - sigaction(),sigsuspend(),Signal(),signal(): use handler_t typedef
* instead of explicit type.
