I have never encountered a *nix on which some sort of ksh could not be
installed easily. On the Open Source ones it is usually pdksh. All the
commercial ones I have used have the genuine article. I use ksh as my
normal shell on all platforms I use (AIX, Solaris, Linux, *BSD and even
Siemens Reliant Unix; I had one running on Windows once too). It's often
not installed by default though. Hence my recommendation to stick to
bourne syntax for maximum portability.

Lazy bastards IMHO. I make both vim and bash available to my users on
AIX if they want them. I do point out that they use them at their own
risk of course, and insist that their management approve. Neither is
hard to build on AIX and if you know AIX at all you will realise that
this is a strong indication that they are not hard on any common
platform.
