Well, if I could find the equivalent to getopts, I think I could
get along without kornshell.  I found this feature to be
extremely useful when I was a heavy-duty KSH programmer, and now
I am coding a few scripts again and would like to take advantage

pd-ksh doesn't implement them either.  It attempts to emulate ksh88, with
a few ksh93 features that POSIX specifies.

The ksh88 and ksh93 features that bash does not implement (with suggested
bash equivalents for a few) are listed in the FAQ.

KSH is pdksh

[Galen Boyer]

After reviewing some archives, I find that pdksh is cygwin's
version of ksh.  Is this still available and where do I get it?
My c:/cygwin/bin doesn't contain it.

Thanks.

pdksh is not Cygwin's version of ksh but rather an open-source version of
ksh which can be built and used under Cygwin.  You can check the Cygwin 
home page for pointers to related sites with ported software and you can
also look in the mail archives for indications that others have ported it
and made it available.  Alternatively, you can just download the source 
from your favorite GNU site and build it yourself.

Ooops, pdksh is _not_ the Cygwin version of ksh. Pdksh is an open
source implementation of ksh which isn't bound to a specific OS.
Latest sources are available in ftp://ftp.cs.mun.ca/pub/pdksh , an
OLD Cygwin binary which only supports binmode mounts is available in
ftp://ftp.franken.de/pub/win32/develop/gnuwin32/cygwin/porters/Vinschen_Corinna/B20

As Larry explained, this is something different.

However, as I've come to discover after much pain, if you're already
using Cygwin, there isn't much point to installing pdksh.  It's easy
enough to create a symlink from "/usr/bin/ksh.exe" to
"/usr/bin/bash.exe".  Poof.  You have Korn shell.  As far as I can
tell, Bash can substitute for Korn shell in every area I'm familiar
with.

I knew that once upon a time.  Thanks for reminding me.  Hey miss bash
maintainer how about a postinstall script to ln -s bash.exe ksh.exe?

Cheers,

Nope, bash is not ksh. There are quite a few ksh93 features that are not
implemented in bash (and possibly quite a few from ksh88 days, but I
don't have details on those).

Please don't. I personally very much dislike misleading links. If people
want ksh, they should go and port it using the AT&T's now open source
ksh93.

Mumit

I'm not going to dispute that, but could you please give us some
examples of ksh88 and ksh93 features that aren't transparently
available in bash?  I'd like to know exactly what problems I could run
into.  I haven't noticed anything yet.  Does someone know which
canonical ksh version (ksh88 or ksh93) the Solaris ksh matches?

It would sure be nice to bring a maintainable ksh into the Cygwin
fold, just for the sake of increased Unix compatibility.

Re: KSH is pdksh

[Matthew Smith]

For what it's worth, I started taking a stab at compiling AT&T's ksh.  Man,
they certainly do use some wacky packaging tools.  At any rate, here are
some of the problems that I encountered, and what I did about them.

1) The 'package' script wants to see getopts.  Thus, I made sh a link to
bash to work around this.

2) The 'package' script always seemed to fail, complaining about not being
in the package root (when it was).  I solved this by editing the package
script to not exit if that particular error happened.

3) I made a link from gcc->cc for convenience sake (read: laziness).

At this point the 'mamake' utility seems to start configuring/making things.
However, it spits out the following errors:

/home/matts/att/src/lib/libast/include/ast_std.h:672: conflicting types for
`rea
d'
/usr/include/sys/unistd.h:72: previous declaration of `read'
/home/matts/att/src/lib/libast/include/ast_std.h:690: conflicting types for
`wri
te'
/usr/include/sys/unistd.h:99: previous declaration of `write'

Can anyone suggest an elegant way around this?

thanks,
-Matt Smith

Well, if I could find the equivalent to getopts, I think I could
get along without kornshell.  I found this feature to be
extremely useful when I was a heavy-duty KSH programmer, and now
I am coding a few scripts again and would like to take advantage

I got notified of the man pages for bash.  It looks really nice
for scripting.  getopts is just how I expected.  Whoa!  Cygwin is
excellent!

Thanks a WHOLE BUNCH!
