As well as its successor, Inferno.

Lots of things are files in Unix; this was copied in Linux.
It was so successful in Unix that they went whole hog in Plan 9 and Inferno.

Mu memory may be failing ne after almost half a century, but I recall
that the original Unix, way back in the early 70's,
even directories could be read as files. Not that there was
some hidden trickery making them into files; instead there were
conventions how files could be treated as directories.
