Speaking of DEMOS, I was browsing through that a while
back (when it
was first posted here;
I guess this: http://minnie.tuhs.org/pipermail/tuhs/2011-May/002387.html
I forgot to post about it at the time) and saw a
feature that
doesn't seem to have existed anywhere else that I could find -
placing interpreter arguments after the command line arguments
of a script.
I.e. something like "#!/bin/foo bar $* baz".
Now that looks like a quite special hack to me,
The mentioned d22.tar.gz -> d22/sys/sys.tar.Z -> sys/sys1.c has
# define SCRMAG "#!"
# define SCRMAG2 "/*#!"
# define ARGPLACE "$*"
# define SHSIZE 70
# define ARGV 11
it accepts both #! and /*#! (equivalent), 70 chars, at most
11 arguments, and explains (russian guessed and then omitted here):
usually
script x with "#!CMD A1 A2 A3"
called as "x B1 B2"
results in "CMD A1 A2 A3 /.../.../x B1 B2"
while in D22
script x with "#!CMD A1 $* A2 A3"
called as "x B1 B2"
results in "CMD A1 /.../.../x B1 B2 A2 A3"
Has any American unix had this?
I haven't seen such anywhere, but not the above until now, either.
But I believe that you can discard those which are listed here
http://www.in-ulm.de/~mascheck/various/shebang/#results
from your list of candidates.
Some these days won't even allow multiple
arguments at all.
Well the original implementation (post 7th ed and 4.0/4.1 BSD)
didn't allow arguments at all ;-) But multiple arguments
definitely is the minority (AFAIK Plan9, some FreeBSD,
MacOSX, Minix, BSD/OS, and some early cygwin).
