I think ksh was the first shell I was exposed to vi command-line editing in on a Sun workstation a long time ago -- I haven't thought about it in years as it seems bash is so prevalent, but good to so some folks still keeping it alive.

You'll still find it as the default shell on at least some BSDs, and I think AIX.
- Crontab 9y ago
  On OpenBSD, the default shell is their fork of pdksh. On NetBSD, it is Almquist Shell, and on FreeBSD, it is Tcsh (IIRC).

    On FreeBSD it's tcsh for root and ash for non-root, oddly enough.

      Interesting. Thanks.

  AIX defaults to ksh88. My first job out of college a long time ago was to maintain and enhance AIX's various installers, which involves some 100KLOC (!!) of ksh scripts. I was one of the first people on the team to move newer projects to Perl- this was early 00's and somewhat fashionable back then, and the only other scripting language supported on AIX at the time. In retrospect, it's possible everything might have been better off left as ksh :-)

    The AIX installp format is my favorite package manager. It was fairly easy to debug it until it hit the ODM. The only time when AIX utility debugging got weird was when multibos went off the rails. I started using ksh on AIX and it has been my favorite shell since then. I've written a few thousand SLOC worth of utilities and customization scripts in KornShell.

    Commercial UNIXen that bundled CDE had two ksh versions - ksh88 installed as the POSIX shell, and ksh93 installed as the CDE graphical shell as /usr/dt/bin/dtksh. The dtksh binary bundled Motif X/Windows support, and scripts could easily and quickly build complex GUI applications. This actually remains the fastest and least resource intensive way to build a quick GUI. https://sourceforge.net/projects/cdesktopenv/ https://sourceforge.net/projects/cdesktopenv/ The dtksh was written at Novell by Pendergrast, who wrote a textbook on it. Modern ksh93 should make this a supported compile option.

I've never used it, but I'm deeply grateful for it because, from what I can tell, without Ksh we wouldn't have Zsh, which I use every day and really enjoy.

  If you like zsh, you're going to love fish† † The qualifying clause is probably unnecessary here.
  - discreditable 9y ago
    Maybe even if not! I didn't care that much for zsh but I love fish.
  - reificator 9y ago
    I love zsh, but am not a huge fan of fish. Lots of non-standard things that don't play nicely with existing workflows. I prefer bash/zsh/etc because of the ecosystem around them. If I wanted to throw that away and start from a different base I'd probably use Powershell or something like it to be honest.

    I love zsh, but abandoned ship of fish long ago.
  - CJefferson 9y ago
    I find fish interesting, because I thought it is what I wanted (throwing away the pain of sh syntax), but now I just have to keep switching between sh and fish and I keep forgetting which is which. I have to write too many scripts for other people, and I can at best assume they have bash. I've gone back to bash, might try out zsh.
    - StavrosK 9y ago
      Why not just write scripts in bash (or, hell, Python?) and use fish as your shell?

My first shell was ksh on a DEC Unix many years ago. That was the first scripting I ever did.

OpenBSD still uses a ksh fork as a default shell. mksh is also widely-available and pretty great -- I use it as my shell on Linux boxes, too.
- throwaway2048 9y ago
  its not a fork of ksh, its a fork of an open source ksh clone called pdksh that predates AT&T ksh open sourcing, and is frankly kinda crap. OpenBSD has improved it, but compared to real ksh its lacking quite a lot, most painfully sane substrings.
  - alxlaz 9y ago
    Right. In the spur of the moment I wrote "a fork of ksh" as in "a shell (mostly) conforming to ksh' specs", which is technically incorrect -- the worst kind of incorrect.

ksh was not my first shell, but as much as you, it is where I use vi command-line editing a lot. It's one of the first shells I really got to grip with as a young budding system administrator. I didn't know any vim really before I went on a Sun scripting for sysadmin course. My Ksh scripting book has served me well over the many years.
