Ok,
another trivia question.
where did xargs come from? I started with Edition 7 (Perkin Elmer
V7 + bits of BSD 2.1) and I am pretty sure it wasn't there.
I have a feeling it was printed in a book as shell script, somthing
like Bourne's book, or Kernighan and Pike but I'am not sure.
Anyone remember?

My recollection (supported by my 1990 book) is that xargs came from PWB
for use with the Mashey shell, before we had the `command` construct.

FreeBSD [1] and NetBSD [2] man pages (see HISTORY section)
seem to confirm PWB as the source.

oh indeed, PWB/UNIX 1.0, here's even some source:
