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.

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.
