Fascinating. As I'd been in Sun OS, and started doing admin work when it became Solaris, I'd missed that bit. A question: did the license agreement include payment, or was it just restrictive on distribution?

In 1990, when I started using ksh88, it was totally commercial. Binaries were $$$ and source was $$$$. We bought the source and compiled it for SunOS, Ultrix and various SYSVr[23] machines (one machine was so old it didn't understand #! and so needed it placed as /bin/sh).

But around 1991 1992, the first Solaris-2.x (SunOS-5.1) came out and this included the Korn Shell for no additional costs.
