I just watched this video with my dad. He had access to AT&T Version 7 and BSD Unixes via an acoustic modem when he was a kid. My grandfather is an electronic engineer and had things like terminals just laying around their house. Thank you for sharing this piece of nostalgia

Sure, roff isn't on Ubuntu, but that's because GNU roff replaced it, and all of the man pages you're looking at are made with groff lol I use groff a lot. You can typeset with it. It's very neat. I'm working on making a legal citation system with it.

Awesome video Robert! for reference, however, I recommend the next time you do this, to use a Unix system with actual heritage to Unix, such as the BSDs (FreeBSD, OpenBSD, NetBSD, etc) or illumos, whose source code comes directly from AT&T Unix. I do also have to point out, that in real(er) Unix operating systems such as illumos, the roff command is still around, and it runs every time you open a man page :) The FreeBSD operating system is my favorite Unix Operating Systems.

Thanks for the note. I chose to use my default Ubuntu Linux for comparison since it's the *nix system with the most broad audience. Honestly, I still find it quite impressive how many of the commands from that list are still available on a modern Linux machine. And even quite a few of the ones that aren't generally have a similarly named command that serves the same purpose (like gdb). As for the 'roff' command, I've come to learn that 'groff' is probably the equivalent version on Ubuntu (although I could be wrong since I'm not familiar with this document formatting method).

Superb job! Thank you. This was really interesting. I am amazed that the only two commands I have never used in Debian linux (which I've been using for almost 24 years) are type and write. I had never even heard of them before.

- to rewind tapes nowadays, you'd use the "mt rewind" command, or use one of the tape device nodes that are set to autorewind. - roff was replaced by nroff, and it is still used today to view manpages on a text console (like you do).

@RobertElderSoftware 9 ай бұрын

Neat! I can confirm that 'nroff' is already installed on my machine as well. I didn't expect 'mt' to be already installed, but it is too!

@bluesquare23 8 ай бұрын

I think nroff is dead and was replaced by groff

@mihiguy 8 ай бұрын

@@bluesquare23 I would say that "groff" is GNU's implementation of nroff just like "bison" is GNU's implementation of yacc. Trademark laws can be confusing.

OpenBSD still has a "mail" command, though it's part of OpenSMTPd

@RobertElderSoftware 9 ай бұрын

I recall that I actually still used the 'mail' command on one of my servers circa 2015 or so. I also recall that there were multiple packages that would install a 'mail' command, and one of them was better (forget which one). And also, there is a 'mailx' command that I found easier to work with.

roff was superseded by nroff which is now emulated by groff -- both nroff and groff should be installed by default =)

The UNIX manual says that there wasn't a "b" command in UNIX either, you can clearly see it at 1:00

@RobertElderSoftware 9 ай бұрын

Yeah, I only noticed that after I had finished editing the video. Looks like the 'b' command was a special case. Later in section 7 of the v1 manual pages, I can see a note for "bc -- B compiler" that says "The b command is defunct at the moment; bc is called from a command file.". So I guess the 'b' command was already deprecated in Unix version 1.

roff has become groff (gnu roff). Not sure if it comes pre-installed by default.

Roff still kind of exists in the form of groff - gnu roff.

@@RobertElderSoftware since the rendering of man pages depends on it, nroff should always be there. Man pages are still written in the run-off language.

~"cat is not a command but a systemcall" I'm sorry what??? I now must do some googling, or if I'm super lazy asking chat gpt to potentially incorrectly give me the answer to what the difference is (you know I'm picking that one). So now I thinking there are not only programs(commands) and shell functions, but system calls? I've really never in my life heard of that in the context of a shell.

@BeefIngot 8 ай бұрын

Ok so I went the lazy chatgpt route and I have to admit, I ended up going down a small rabbit hole as I realized I knew what a system call was, but never really directly made any myself. I ended up reading about how behind all the really mollases slow js ultimately its all pretty abstraction layers to do dirty feeling writing to specific registers dependant on architecture and its prettied up the entire way up till you reach the disgustingly 🤢 bloated dependency rats nest of any modern nodes project. I jest there somewhat but it's actually quite interesting just how much is abstracted from everyone at any given time. Heck, even assembly is a pleasant abstraction vs the logic below it and we're all depending on the abstractions of each other. I'm not going to start singing kumbaya or anything but it was an interesting thought. Cat is totally a command though. Like it's main function is to trigger a syscall, but it is indeed totally just a command. .maybe I misunderstood what was being said in the video however, but it got me to learn something new, so it's a win either way.

What about Arch Linux

@RobertElderSoftware 9 ай бұрын

According to this url: archlinux.org/packages/core/x86_64/coreutils/ The latest version of coreutils is 9.3-1 And according to archlinux.org/packages/core/x86_64/binutils/ The latest version of binutils is 2.41-3 In the github README for coreutils release 9.3: github.com/coreutils/coreutils/blob/f386722dc0d996d5379f12b4a8d4dd15ca7df4b5/README You can see a listing of all commands that are included, many of which are the original unix commands. And at this url: www.gnu.org/software/binutils/ You can see a listing of many of the commands that are in binutils. You'll recognize that some of these are in fact the same commands from this video.
