Ask David Korn About ksh And More

Posted by timothy on from the and-his-critically-acclaimed-pop-music dept.

David Korn is the author of the famous Korn shell, ksh, which deserves consideration next to the ubiquitous bash. Quote (regarding the AT&T research group he's part of): "We don't write anything in Perl anymore, because [ksh93] has all the functionality built in." He's also an AT&T fellow, and heads up the UWIN project, which "provides a mechanism for building and running UNIX applications on Windows NT, Windows 98, and Windows 95 with few, if any, changes necessary." This is the software that allowed some crazy folks to run GNOME on Windows several weeks back as well. (And is available for no-cost personal use.) This is the same David Korn you may remember from this picture. I met him at a recent NYLUG meeting when he spoke about the Advanced Software Technologies collection of tools, now Open Source, and he graciously agreed to field questions in the usual Slashdot interview style. So please leave your questions in the space below --1 question per comment, please -- and Korn will get back to you with answers in the near future.

  1. True Story? by travisd · · Score: 5
    Was the story about you embarrasing a Microsoftie at a conference true? Specifically, that he was insisting that their implmentation of ksh in their unix compatibility kit was true to the "real" thing and trying to argue the point with you. The argument ended when somoene else finally stood up and informed the speaker who he was arguing with.

    Just curious...

  2. UWIN and etc by rabtech · · Score: 5

    You once said that you had to learn Windows NT because you couldn't criticize what you didn't know. What I'd like to know (as a primarily Windows programmer) is what do you consider to be the best and worst parts of both the Windows NT/2000 model and the UNIX model. What advice can you give? Also, has working on the UWIN project given you any insights that you can share with the rest of the community?

  3. Public Apology by watanabe · · Score: 5
    Dear Dr. Korn, I feel I owe you an apology, and this seemed like a great chance! I went to school with Adam at Brown. And, in 1993, my roommate, Matt Smith, woke me up at about midnight, excitedly telling me "Do you know the Korn Shell? This guy's dad wrote the Korn shell!!!" He was coming in with Adam from somewhere.

    I sort of turned over in my sleep, (I was extremely groggy), and said "I hate the Korn shell." and went back to bed. Adam never really talked to me after that, although he was polite enough to me at parties.

    So, Dr. Korn, I feel I owe you an apology. I didn't mean to disrespect your lifework in front of your son! I still can't use the korn shell, but call it fear of the unknown, please, rather than lucid comments on your code.

  4. Comparison by Shadowlion · · Score: 5

    Background: the only shell I've ever really used is bash. Bash has always seemed to be the standard UNIX shell (or, at least, the standard default UNIX shell), and for the most part I've always been able to do what I wanted in it.

    Question: can you engage in a little unadulterated advocacy for a moment to offer some reasons why an informed user might consider using ksh over bash or other popular UNIX shells? What does ksh provide that other shells don't? Similarly, can you give a realistic appraisal of ksh's drawbacks as compared to bash or other shells?

    Thanks.
