Default Where to obtain OpenBSD's pdksh

I looked through the 4.6 i386 packages list but I can't find ksh or pdksh (I want the OpenBSD version). I want to compile the source on another OS but I can't find the download on the OpenBSD packages page. Where can I obtain the official copy of OpenBSD's pdksh?

It is not a package, it is distributed as part of the operating system.. it is the default ksh implementation.

The developers have customized it over the years for use on OpenBSD, a few 3rd party projects have ported it elsewhere though.. AFAIK those efforts have stalled.

You can find the source in the CVS tree, or in the src.tar.gz tarballs put out with each release.

Some people ported OpenBSD's ksh to other systems. You may want to search for that on the Internet. I'm not sure if these versions of ported KSH is maintained or up to date.

You can check out mksh, which is close to OpenBSD's ksh

You can checkout the ksh code from OpenBSDs CVS and build it. Last time I did was on FreeBSD 6 or 7, it only required changing like two lines of a header file.

The mksh that bmk1st mentioned is also an option, although I haven't used it enough over the years to note compatibility levels with modern OpenBSDs own shell.

Thanks. I don't like the default ksh because it doesn't have some features like the history completion with up/down arrows and tab completion, etc.

But after using OpenBSD's version for a while it seems like my preferred shell of choice. I don't think I even realized it was ksh

I've found ksh93 a bit buggy if that's what you're referring to, but it can be setup with a sexy completion system, if a bit unorthodox.

mksh is based off openbsd ksh, except for some things that are useless (mailbox checking) or positively break stuff (multiple ulimits in one command, bash-like PS1), or aren't done nicely and will be done differently (generic emacs multikey bind).

I keep track of OpenBSD ksh, even (and it amuses me when they fix bugs I fixed years ago, so I just need to bump the RCS Id I use for tracking).

This thread is over 3 year old, what's your point?

Besides, OpenBSD doesn't develop an "OpenBSD ksh"; as far as I know, it is pdksh.

I could be wrong but if I am not mistaken Mirabilos is the Linus/Theo of MirBSD OS

See https://www.mirbsd.org/ and https://www.mirbsd.org/mksh.htm

Interesting, because from the OpenBSD ksh man page:
Quote:
KSH(1) OpenBSD Reference Manual KSH(1)

NAME
ksh - public domain Korn shell
...
...
...
AUTHORS
This shell is based on the public domain 7th edition Bourne shell clone
by Charles Forsyth and parts of the BRL shell by Doug A. Gwyn, Doug
Kingston, Ron Natalie, Arnold Robbins, Lou Salkind, and others. The
first release of pdksh was created by Eric Gisin, and it was subsequently
maintained by John R. MacMillan (change!john@sq.sq.com), Simon J. Gerraty
(sjg@zen.void.oz.au), and Michael Rendell (michael@cs.mun.ca). The
CONTRIBUTORS file in the source distribution contains a more complete
list of people and their part in the shell's development.
