Look in comp.sources.unix for information about how to retrieve files. I have not used "bourne" or an archive site so I can't comment on them. The description of "bourne" said it was the Bourne shell with job control, tilde, history, and some other stuff. This is available for little or no charge. I don't know if it will port to SVR[23] but it is probablys good start. -- Larry Cipriani AT&T Network Systems at cbosgd!osu-cis!tut!lvc Ohio State University

What is the status of the sh(1) released with MINIX ? It's a re-implement of the Bourne shell, and isn't it freely distributable ? Might not be too hard to get a copy of that and hack and snip... --mjr(); -- Once, there was NO fun... This was before MENU planning, FASHION statements or NAUTILUS equipment... Then, in 1985.. FUN was completely encoded in this tiny MICROCHIP... It contains 14,768 vaguely amusing SIT-COM pilots!!

Minix (including utilities) is copyright by Prentice Hall, with limited redistribution allowed, and that for educational purposes only. However, someday, hopefully, GNU will provide you with what you want.

The "bourne" code is patches to the source for the 4.2BSD Bourne shell, which is even worse than the original idea: I have to buy not only a SVR3 source license, I need a 4.3BSD license too! The simplistic answer, BTW, is to use a front end; I've seen a shell script front end (bcsh) and have contemplated one in C, but in order to have the front end not choke on Bourne shell programming constructs (and believe me, I use them. Often.) I'd have to virtually rewrite the Bourne shell from scratch into my front-end; while this effectively obviates the need for /bin/sh as a back-end, it makes things far more complex -- and, while I consider myself a fairly good programmer, I *know* I'm not up to writing a Bourne shell. (My last attempt showed me why csh parses the way it does.) Oh well, I may as well admit defeat on this one. -- Brandon S.

I did hear that someone was working on it, but I haven't seen any results yet... probably a proof that it *is* a nightmare to add those abilities. -- Brandon S.

(My last attempt showed me why csh parses the way it does.) In the UNIX/WORLD Volume IV, Number 5, May 1987 - there is an article called "Making History" by Ray Swartz, which describes how to write a frontend to the bourne shell providing it with a history mechanism, saving of history, editing of history. The whole script is 114 lines code. I haven't tried it so I don't know how eficient it is! For more information refer to the magazine or if you can't get hold of a copy to dropping a letter to Ray Swartz at the following address: ihnp4!sun!uworld!ray Happy New Year Kim Chr. Madsen.

I tried it before I had ksh. The basic problem is that it (and all my attempts to front end sh) break system 5 functions. I don't remember exactly why though.
