I have v8 on the VAX (SIMH) running but as it doesn't have TCP/IP it fell
into my pile of "I'll try some porting later" and never got picked back up.
I also have v9 on a Sun in TME and now that the NME project has resurrected
and enhanced that, shall we say, very particular emulator I should fire it
back up and see what I can get running. I'd love to have v10 on a VAX but
my preliminary efforts to get v10 going from source on v8 were not very
successful; I suspect that it's just too big of a leap.

A lot of the vi visual-mode commands were inspired by emacs, like
forward/back words, sentences/statements, paragraphs/functions. I
specifically remember explaining the hierarchy of ctrl-f, meta-f,
ctrl-meta-f, etc., and then Bill went off and put in '{' and '}' and
similar commands. And the "yank" commands were named after ctrl-Y and
other "yank" commands in emacs. Those are on the 2BSD tape.
Earl Cohen did the "finger" command quite soon after our class of first
year grad students arrived at UCB. It's in 2BSD.
I did "more" really early (https://danhalbert.org/more.html), but my
very simple version did not get back into the sources, and the reworked
"more" that Eric Shienbrood did is in 3BSD but not 2BSD.

I'm curious if you remember any other features that Bill might have
picked up from Emacs or ITS? From you or anyone else.
Another interesting example would be job control that was done by Jim
Kulp.

IIRC Dark curly hair, and I can not think of his name either.
I bet if I saw a picture, I could identify him. apropos(1) was a great
hack, but I always thought whoever came up with locate(1) really hit the
jackpot.

That definitely tracks with an outlier I turned up in my search of sources,
an "apropos.doc" that appears on the CSRG DVD with the sources for CMU
Emacs. It's just a list of mappings from commands to keybindings, for
example:
...
delete-next-character ^D
delete-next-word ESC-D
delete-other-windows ^X1
delete-previous-character ^H
delete-previous-character RUBOUT
...
I'm not particularly an Emacs person, but it looks like it could be the
output from an "apropos" command, or perhaps the input to it.

I was one of the Berkeley grad students in the office with Bill Joy
around this time. I think the name probably come from the "apropos"
command in Emacs. That command is mentioned here:
https://worrydream.com/refs/Stallman_1979_-_EMACS,_The_Extensible,_Customizable,_Self-Documenting_Display_Editor.pdf,
which is dated June 1979, but the Emacs command existed before that
date. The Berkeley source code is dated 1979:
https://minnie.tuhs.org/cgi-bin/utree.pl?file=2BSD/src/apropos.c
I had used Emacs at MIT as an undergraduate. Bill would sometimes ask
me, "how do they do that in Emacs", or ITS, and then riff on a feature
and put it into vi or whatever. Whether I suggested an "apropos" Unix
command or someone wanted something like that, or I said, "sounds like
'apropos' in Emacs", I don't remember.

Looks like it was introduced in 2BSD, written by Bill Joy, though the
4.4BSD manpage claims that it was introduced in 3BSD. Neither the BSD
source nor manpage are particularly enlightening about the choice of name.

This makes me wonder when the `apropos` command was introduced; surely
the name was also somewhat of an obscure joke ("what is apropos of
listing a directory?" is not exactly the phrase that springs
immediately to mind when wondering how to list a directory).
But the other form of it, `man -k`, is reasonable. Plan 9 called the
similar thing, `lookman`.

The DECwriter LA36 was acceptable, though.
While DCL commands generally involved complete words, they could be
abbreviated to the smallest unique abbreviation. Thus one mostly typed DIR
instead of DIRECTORY. Command keywords also were be required to be unique
in the first 4 characters--the DCL parser ignored all but the first four.
characters. The engineers at DEC's Marlboro MA facility named one of their
networked machines TWINKIE so that to log into it they could type SET
HOSTESS TWINKIE.
The terse Unix command verb style can be a steep learning curve for
beginners. How is one supposed to know that you say 'ls' to get a
directory listing? And unfortunately man pages aren't very useful for
beginners because you have to know what the command verb is in order to
call up its man page. Unix lacks a place to ask questions such as "how do
I get a directory listing?".

Since (and including) 2020, 9front has averaged 700 commits a year to
the project, a very large portion of that being bug fixes and upkeep.
We've also been presenting some of the more interesting new work at
recent IWP9 conferences, now that they've become a yearly occurrence
again thanks to the Plan 9 Foundation. From my perspective things
have been quite lively lately.
We did take a look at your rc parser changes (closer to when they were
first pushed to plan9port) but had decided not to adopt them at the
time.
Thank you,
Jacob Moody

I looked at https://9p.io/plan9/ and also 9front and neither has the change.
I don't think either is particularly maintained at this point.
(I made the change in the Unix port of the tools,
https://9fans.github.io/plan9port/.)

I'm a little late to the thread, but this is not quite true.
rc's lexer and grammar treated = as a special
symbol - just like ( or | or & or ; - and so it couldn't
be used as a literal except when quoted.
That is, "foo x=y" was a syntax error, not an equivalent to "x=y foo".
One of the tidyings I did during covid lockdown was to rewrite
rc's parser not to use yacc anymore [1], specifically to make
it easy to allow "foo x=y". As I wrote in the commit message,

p.s. And I did use PDP-11 Unix on an upper-case-only ASR33 by typing
backslashes before all upper-case letters to keep them from being mapped
to lower case.

I am sure that shorter shell commands and switches were helpful for
*anybody* typing on a clunky, electro-mechanical Teletype (former TM).
They were for me, even though I had learned some typing in school on
mechanical typewriters.
For the counter-example, I wonder if anyone ever tried to type very much

https://github.com/rakitzis/rc --- This is Byron's reimplementation.

There is also https://github.com/benavento/rc ; I didn't know that
Byron had made rc available directly.

That is plain broken, but I can see how it could/would work; something
like "A=B blah A=C blah"?

Which is why I've always quoted anything not strictly alphanumeric; you
never know what the current shell will do (especially if it's CSH[*]).

Wait, when did that happen? And more importantly, _where_?
The GNU Coreutils version (according to both --help and the man page)
only appears to support the JCL convention and in fact complains and
aborts when fed Unix style arguments. The NetBSD version behaves the
same way.

In the liberal arts world where my background is, IBMs were not a sure
thing. My alma mater was a DEC shop top to bottom starting in the early
'70s. The psychology department had a PDP-12, I believe the natural and
computer sciences had a few 8s and 11s (and CS later an 11/750), and I know
that the "computing center" (mostly administrativa) got an 11/780 pretty
much as soon as they could. When I got there everything was still all DEC,
VMS for the computing center (a 6620 clustered with some smaller boxes,
also serving email and news) and mostly Ultrix on MIPS for the sciences.

I am (considerably) over 50, but was fortunate enough to never have
to have used JCL. After a two year hiatus for religious studies,
I returned to my university for my senior year and encountered
Unix (IS/1 on a PDP-11/70), C, and Software Tools. It was sooooo far

I think it was only Plan 9. The change was motivated by the
rc shell, which treated x=y anywhere on the command line (not just
at the beginning of a command) as a variable assignment.
(For a while I used Byron's rc. I was used to typing
echo ===============
to generate separator lines. rc threw a syntax error at me. :-)

I feel like I would somehow be remiss if I did not point out that the
formidable Rick Troth just put XFL, which is more-or-less a port of CMS/TSO
Pipelines to POSIX, up on GitHub.

Yeah, I know. But you can get away with '//dd if= ...' which

Never seen that either, POSIX doesn't suggest any support for that either, with this in the RATIONALE section:
---QUOTE---
The OPTIONS section is listed as "None" because there are no options recognized by historical dd utilities. Certainly, many of the operands could have been designed to use the Utility Syntax Guidelines, which would have resulted in the classic hyphenated option letters. In this version of this volume of POSIX.1-2024, dd retains its curious JCL-like syntax due to the large number of applications that depend on the historical implementation.

That won't work. The data definition JCL statement format
is more like this:
//<name> DD <parameters>
optionally continued by one or more of
//<spaces> DD <parameters>
...

POSIX actually speaks on this:
"The standard input, standard output, or both of a command shall be
considered to be assigned by the pipeline before any redirection specified
by redirection operators that are part of the command"
https://pubs.opengroup.org/onlinepubs/9799919799/utilities/V3_chap02.html#tag_19_09_02
In the general case, this is how things like
program 2>&1 | collect_stdout_and_stderr
can work (file descriptor 1 is associated with the pipe before fd 2 is
redirected to it).

I suppose this depends entirely on the shell; perhaps that is the
point. Arguably, being the target of a pipe _and_ having a redirect on
stdin should be some kind of an error, but regardless, something that
is true is that is that the second `cat` command will only see
whatever is on `stdin` as it reads from `/dev/stdin`, but what is _on_
stdin can be confusing.

I'm not sure of the point you are making with your last example, which
gave me pause. I had to run it to see what it does.
I correctly guessed that only one of thing or otherthing would be printed,
but I was not able to guess if the | or the < would take precedence.
Is there a simple reason why the < has priority over | for the stdin ?
If the < precedence was your point, why did you specify /dev/stdin ?
cat thing | cat < otherthing
makes the point.
Is there a finer point I am missing ?

I have always admired one letter commands in ed(1) and during the years
constructed my own personal perfect Unix dictionary with most often used
commands as one letter abbreviations. For cat(1) I have always used 'c'
(cee) which also denotes one of its main functions.
Grep(1) is 'g', vi(1) is 'v', etc.
It makes typing a little faster, at least for me.

James Gosling used this idiomatic JCL command (see loop body) in something
or other, and Brian and I borrowed it (with attribution) for the bundle
command in our book.
% cat /usr/local/plan9/bin/bundle
#!/bin/sh
echo '# To unbundle, run this file'
for i
do
echo "echo $i"
echo "sed 's/.//' >$i <<'//GO.SYSIN DD $i'"

I looked through a broad swath of dd source files and man pages from v5 to
System III and SVR4, the BSD SCCS tree, various commercial UNIXes, modern
BSDs, and modern Linux but none of them have any sort of explanation of the
name. I figured I'd at least find something!
It is the case that many places refer to the command's function as "convert
and copy," so I wonder if it's some sort of play on the fact that the
expected name of the command might be "cc".

You know, this is a place that might actually be able to provide a
definitive answer to me. A brief web search found me asking the same
question in 1995.
When I were a wee lad, I was told `dd` was short for `do DEBE`, which,
while obviously referencing a well-known movie about a Northern Texas
sports team and their most enthusiastic fan, also referred to the mainframe
software whose name was an acronym for `Does Everything But Eat` and whose
function was to copy data across sources with very different blocking and
representation conventions...which is kinda what `dd` does.
Can anyone here confirm or deny that origin for the utility's name?

cat is capable of endless discussion.
cat thing | cat otherthing doesn't do what (some) people think.
cat thing | cat otherthing /dev/stdin does, but there's an ordering
point to be made.
cat thing | cat < otherthing /dev/stdin makes the ordering point. and
the number of lines seen.
the role of the shell in marshalling the IO and determining what is
opened, when, truncated is another pitfall that seems to escape
people. "I thought the commands ran left to right" when your first
command < something and your final command > something
like others, my use of cat is reflexive. I know perfectly well I could
solve the whole problem in awk or sed, I still construct sequences to
use sed to edit the lines, and awk to extract the fields in LSWP
denoted counts. we're speaking english and say "comme ci comme ca" and
nobody blinks, it's the same in shell. codeswitching!

I suspect that only "highly educated east-coasters" are
familiar with "catenate." My education was pretty good,
but catenate, for all it's advantages of brevity and similar
age to "concatenate" is simply never used in modern-day
American English.
I'd never heard it until, like just about all the rest of
us, I came across it in the Unix manual.

First, it was mnemonic for the ed(1) syntax g/re/p, and second
have a vowel in it (instead of calling it grp) made it easily
pronounceable.
I also suspect that at this point we're overthinking it. :-)

Muscle memory. dd is weird but you sort of get used to it and then just
do it how you always have.

For me the fascinating thing about dd is that people tended to use the JCL
notation for its arguments even after the Unix style was made available.
That is, people prefer "dd if=foo" rather than "dd -if foo" or even the
obviously easiest "dd <foo".
It's a counterargument to my understanding of why people prefer "cat foo |
cmd" to "cmd <foo" or "<foo cmd". There's a psych thesis in there somewhere.

i doubt there is a fully satisfactory answer. dd was a jab at IBM JCL.
Several later commands were derived from earlier ones, like sed and
tar. And awk ...
I think the one that needs more explaining is grep. If brevity were
the sole criterion, it could have been shorter.

I'm not sure the answer was ever written down (e.g. in a memo); we will
probably have to rely on memory - and memories that far back are now fairly
thin on the ground by now. Perhaps Mr. McIlroy (or Mr. Thompson, if we're
_really_ lucky) will humor us? :-)
I have the impression that some of the names are _possibly_ inherited from
Multics (which the early Unicians all used before Unix existed) - but maybe
not. The command to list a directory, on Multics, is 'ls' (but see below) -
but the Multics qcommand to remove a file is 'del' (not 'rm'); and change working
directory is 'cwd'. So maybe ls' is just chance?
Multics had a 'feature' where a segment (file) could have additional names (to
the main name), and this is used to add short aliases to many commands, so the
'base name'' for the directory list command is 'list'; 'ls' is a short
alias. A list of Multics commands (with short forms) is available here:
https://www.multicians.org/multics-commands.html
I'm not sure how early that alias mechanism came in, though; my copy of
"Introduction to Multics" (February, 1974) doesn't have short names (or, at
least, it doesn't use them).
It won't have anything to do with disk and memory. Having used a Teletype, it
would take noticeably longer to type in a longer name! It's also more effort
and time. I would expect those are the reasons for the short names.

Early on, here in Faraway Land, I was told Unix command naming rules were these:
however can’t recall seeing it written:
2-7 chars - ie. short + reserved single chars for personal use
lower case
non-dictionary words - allowing 3rd party software a clear run
Of course, “sort” fails those rules :)
BSD didn’t use those rules (backup & restore).
For non touch typists, shorter commands & keywords are helpful.

Multics had long names and short names for many commands. `ls` was the
short name for `list`, for instance. See "additional names" in
https://multicians.org/mga.html.

(original author of the `more` command`, considered to be a long name by
some and short by others! https://danhalbert.org/more.html)

Before I got hooked on UNIX in 1977, I used a Univac Exec8 system.
You “cataloged” (created) a file with the @CAT command.
Other, file operations were done by the File Utility Routine/Program
Utility Routine: FURPUR
(sort of like pip on steroids).
I decided that if I ever got a CAT, it would be named FURPUR. That
happened when I was working for Rutgers. Not having any UNIVACs
around, the name escaped notice until the EE department hired a guy from
the University of Maryland who says “You have a cat named FURPUR?”

Ken Thompson wrote "cat" for the PDP-7, with "concatenate" in
mind. The cat(1) page in the v1 manual is titled, "concatenate (or
print) files". Only later did someone in Research--I don't know
who--remark on the existence of the shorter synonym. It was
deliberately adopted in v7, perhaps because it better mirrored
the command name.
But brevity is the defensible argument for "catenate", while
familiarity boosts "concatenate". It stll takes some conscious
effort for me to use the former, However, I sense sinister
vibes in "concatenate", driven by the phrase "concatenation
of events", which often is used to explain misfortune.

Ericsson corrupting the use of English words is not news to me,
as I've had some exposure to various Ericsson operations
at that time (and onwards).
It can be noted that they were deep into the process of replacing
Swedish with English everywhere, in documentation and (internal
as well as external) communication. To this end, and to alleviate
the pains of most senior execs (many of who were of a generation
where German, not English, was the first foreign language studied
in primary schools), Ericsson invented some rather Pidginesque
internal variety of English that actually was branded "Ericsson
English." It wouldn't surprise me if "Användningsfall" (which
is a term in Ericsson "PROPS" process management methodology)
was translated to "use case" there already before Jacobson
used it in his documentation.
It's no surprise that "Ericsson English" basically was Swedish
with word-for-word replacements. This abomination was surprisingly
usable, probably because they're both Germanic languages
who were mutually intelligible until maybe 1000 years ago.

Just gotta say, I completely agree with this sentiment as regards
catenate. Also, I've never been sold
on use-case, either. If I remember, it was Jacobson who popularized the
term. Maybe use-case was contrived
to provide some further distinction from the uses connection... as in
the use-case:
Validate Password uses Enter Password...
Personally, I think a use is fine and it doesn't matter much that in a
use, an actor uses a function...but hey,
technical fields are well known and loved for using language in
perfectly unreasonable ways. Technical language is used, ostensibly, to
disambiguate, but more often than not it obscures and alienates. In my
classes, I spend a lot of effort breaking things down into simple terms
while pointing out the use of jargon and the importance of nailing it
for the chosen profession - likening it to a cult of technicality. Big
fan of KISS here :). Terms should mean what they say so professionals
can say what they mean... clearly and with as little ambiguity as is
reasonable, that is, language affords a great deal of redundancy and we
should not be afraid to leverage this tool as well - leave the hunt for
perfect disambiguation to the mathematicians.

"use case" is a case of the use of both of the words "use" and "case",
compounding (confounding ?) them, they specify the use of "case" to
identify (and emphasize) a specific "use" (or set of uses), as distinct
from other cases in which so much attention has not been paid to which
uses they serve. I'm having fun with words here but, like test cases can
be used to isolate (or mix) certain behaviors, use cases might be
crafted as examples, for the purpose of distilling from them, clearer
requirements. I think the requirements people were trying to borrow the
style of language from the test people. But many times it's probably
just jargon-y technical sounding buzz-wordery meant to make things seem
more important than they are.

Usually context makes the nominal use of "use" clear : "many uses", "the
use",
"some uses". I'm not persuaded that "use case" disambiguates any more
reliably.
How do supermarkets display their wares?
For some use cases they use cases.
Metacomment. While the "use" in "nominal use" above must be a noun,
"nominal" isn't compelled to have the intended meaning of "being a noun".
It's a game of whac-a-mot. Kill one ambiguity and spawn another.
