helios supported DAG shell syntax.
Wikipedia:
"What is not immediately apparent is that Helios extends the notion of
Unix pipes into a language called Component Distribution Language
(CDL).
I have somewhere the CDL reference: a small volume, perhaps 50 pages.
If I recall correctly, there’s some discussion in the two Helios books as well. I can
dig them up if there’s interest.

helios was a
unix style os (was it actually posix compliant?) for networks of transputers.
Mostly.
I think it was missing fork(), although I believe it had a vfork().
It was able to run a lot of the free software of the time with a little effort. There was
a GCC port, gnumake, MicroEmacs, X11R4 (? Maybe R5?)
It was an interesting OS. Not unlike Plan9: its file server protocol is roughly analogous
to 9p.
