The challenge here is to identify the 1983 Unix, or whether it is indeed one single Unix.
It has the old line discipline defaults for the eof, kill, and interrupt special characters. But it also has a job control shell and the susp special character. It does not mention either Mail or mailx. login is apparently the shell built in that overlays the current shell, and there are both vi and ex for the visual and line mode editors. But there's a help command, too.
- bitofhope 8y agoSo, in 1983 I think the possible variants are 4.2BSD, SunOS 1.0, Xenix 3.0, SVR1. Someone in a sibling thread mentioned the kill line characters were already replaced around 2BSD. SVR1 had vi and ex, too. `lpr` is BSDian, I think, but maybe System V included that too as an alternative. It's hard to tell, really. At the time SVR1 was out and included fairly many bits of BSD in it, as did Xenix. The only thing I can really say is that SunOS is unlikely, since it was designed for workstations with video monitors from day 1 and the kill characters seem anachronistic since erasing was a standard feature in terminals already and default behavior in current BSD.
