No, it was there, in 6th and 7th editions and thereafter.  A
xenograft from USG, but there, albeit with a BUGS section
saying "The syntax is painful."

There are those chipping away at this.  Part of the problem
is that the SCO Unix property is (or has) transitioned to Caldera.
Yet another new company in which to find someone who can make
a decision.

Unfortunately, there has never (to my knowledge) been a really
satisfactory tree walker in any version of UNIX.  Even "xargs",
which one would think would be debugged by now, fails when
there are spaces, ampersands, etc. in leaf names.  I know of
several attempts to provide library or kernel support for tree
walking; the reason none were specified for POSIX <dirent.h>
(which I was the main proponent for) was that none of them had
worked well enough in practice to make a convincing case that
they should be standardized.  I think this is a solvable problem
for which a really good solution would eventually attract users.

Whoops; okay, I stand corrected.

Isn't Caldera very much into the whole, ``opens source'' bit?  Perhaps
that can be leveraged....  Of course, I can sympathize with the dealing
with a new company's beaurocracy issue.  On a personal note, if I can do
anything to assist with the efforts of those working on this, I'd be
more than happy to offer what limited resources I have.

Apparently Caldera is already moving in the desired direction.  See

as the drift continues :

if you follow the opinions of the /. crowd you'll know Caldera is
not considered hardcore OSS. Some evangelists are positively hostile
to them. I'm neutral on the issue (read reasonably ignorant).

I wasn't taking a position on what church Caldera worships at, I was
merely suggesting that their willingness to open the source to Open
Unix 8 may be an indication that they would be willing to release the
source to the research versions of Unix as well.

That is good news; the time might be ripe to try and contact the
folks who are behind that effort and prod them gently about the
research Unix source.

Gee, I hope no-one tells them that Brian Kernighan has been able to make
his awk available for going on eight years now.  First via netlib, these
days off his home page (http://cm.bell-labs.com/who/bwk).

Brian's version should be preferred out of the two;  it looks to have
more bugs fixed.

    echo awk | awk '{gsub(/a/, "\\\\&")} 1'
