How about the word "magic"? Of course there's /etc/magic that's used by the `file` command. By the way it identifies itself, doing `file /etc/magic` works.
I think the spool with usr written on it most likely refers to the /usr/spool directory, where user mailboxes (and I think print jobs) were traditionally kept.
Somehow I had never heard of/seen this before. It looks like a prog rock album cover or something.
Some old commands in there I haven't used in a long time (poke, uucp), or never used - I think the troff I know is actually the one in GWBASIC (tracing off).
Much of the acceptance of UNIX at Bell Labs was due to its role as a typesetting system, with troff, eqn, and tbl commands. I worked for a UNIX support company (Interactive Systems Corporation) and our first customer was the U.S. Supreme Court because they deal with so many documents.
DECSYSTEM 20 BASIC User's Guide: LISTREVERSE command
LISTREVERSE
LISTNHREVERSE
LISTREVERSE and LISTNHREVERSE print the contents of the
user's memory area in order of descending line numbers.
LISTREVERSE precedes the output with a heading,
LISTNHREVERSE eliminates the heading.
LISTREVERSE
EQUIV 10:53 13-NOV-75
40 END
35 PRINT "THE EQUIVALENT CURRENT IS",I, " AMPERES"
25 I=E1/R
10 INPUT R
5 INPUT E1
READY
The #38 is controversial as noted. To me it represents the branching of Unix flavors, mostly derived from the AT&T and BSD versions (represented by the glasses.)

I would happily pay for a high quality print, but no idea where to get one from.
This is amazing. Does anyone know how to get a physical copy?
The Internet Archive offers a 32Mb PNG file. Download that one and take it to your local print shop.

One of the previous times this was posted, someone offered to print and ship them. I got a A2 sized canvas print. It hangs in my home office now.

The TRS-80 has TROFF and TRON!

More useful but not quite as magical as DECSYSTEM 10 and DECSYSTEM 20 BASIC's "LISTREVERSE" command!

Chalk one up for DEC and BASIC. What other programming languages support that feature, huh?
Now all you need is a COMEFROM and COMESUB and RUNREVERSE (or NUR) statements, and you can write reversible BASIC programs!

Emacs should have an edit-reverse-mode!
#28, pwd, looks like a play on words with "powder" that you would put in a box.

To me, the stuff that grows from a shell invocation must be a process tree.
Quite. I felt reminded of Git but it did not exist yet in the 1980s.
