Yes, it looks like a manual bug. Retrieving the true number of indirect blocks isn't possible from the 7th edition stat. I'm not sure when (or by whom) the st_blocks member was added. > While I'm at it, the V7 ls -a option only adds . and .. to the > list; apparently all other dot files were printed by default. > When did ls change such that -a applied to all dot files? UCB or USL did this (I'm sure which first). Both tended to use more . files. Dennis

The nameless horror of dotfiles [was (no subject)]

by norman＠nose.cs.utoronto.ca

Dennis Ritchie, on ls discarding all names beginning with .: UCB or USL did this (I'm sure which first). Both tended to use more . files. Judging by the manuals, Research did it first. In every manual from 1/e to 6/e, the entry for ls(I) has this description for the -a option: list all entries; usually those beginning with "." are suppressed I always thought this was just a quick-and-dirty way to skip the . and .. entries; the sort of shortcut that was common in the good old days when everything was written in assembly language. That the USL system kept the old convention probably reflects its PWB heritage; both the latter system and that of Berkeley had already invented lots of configuration files clumsily hidden by putting . at the beginning-- more than ls had options at the time--and I guess they felt it was better to let sleeping dots lie. Incidentally, in 1/e ls(I) had a whopping five options: l, t, a, s, and d, each with the same meaning as now (except that -s is described simply as `give size in blocks for each entry' with nothing about accounting for indirect blocks or other overhead). Who says we haven't made decadence, er, progress over the years? Norman Wilson Toronto ON PS: I've lost track. Did the original Subject: line of this thread of conversation get lost because it began with a dot?

question about V7 ls(1) vs. sys/stat.h and ls.c

by Aharon Robbins

Greetings all. The V7 ls(1) man page says that the -s option, which prints total blocks, includes any indirect blocks. However, the V7 struct stat didn't have the st_blocks member in the struct stat, and the code in ls.c uses long nblock(size) long size; { return((size+511)>>9); } So, is this just a case of the man page being mistaken? When did the struct stat acquire the st_blocks member? While I'm at it, the V7 ls -a option only adds . and .. to the list; apparently all other dot files were printed by default. When did ls change such that -a applied to all dot files? Thanks, Arnold Robbins

Hi, What do you make of the SCO (Caldera) lawsuit? Does it affect the archive in any way?

I was given a disc image of the system for the PDP11 I'll try to dig it up for you.

[pups] Fwd: Re: Concurrent Pascal, Solo OS, et al

by Wesley Parish

I asked Per Brinch Hansen recently about Solo and Concurrent Pascal, for use on the PDP 11 simulators, et al, and I received a reply today. This is it. I am wondering, does anyone have any clue as to where these copies of the system might be squirrelled away? How many might've seen it at their Universities?

At Caltech we prepared a distribution tape for the PDP 11/45 with the source text and portable code of the Solo system, including the Concurrent and Sequential Pascal compiler. The system reports were supplemented by implementation notes. By the spring of 1976 we had distributed the system to 75 companies and 100 universities in 21 countries. Later, other people moved the system to the Interdata 8/32, NCR 8250, Modular 1, LSI 11, IBM 370/145 and many other computers. Sad to say, I no longer have a copy of the system (and I don't know who does). Per Brinch Hansen ------------------------------------------------------- -- Mau e ki, "He aha te mea nui?"

Looking for obscure unix information

by Apostolos Koutropoulos

Hi to all, I stumbled on your mailing list and I thought this would be a good place to pose my question. I was looking around for information about several little known (to me) unix derived Oses. AMIX (Amiga Unix) RISCiX ArchBSD Lynx Inferno Helios What I am looking for is basically what versions existed and when they were released, and also from where did they originate. For instance I know that RISCiX originated from BSD 4.4 but that is all I know. I also know that inferno grew out of the research for plan 9, but what version of plan 9 it evolved from I don¹t know. Anyone know the above info? If not any idea where I can look for further info? Thanks :)
