    Question UNIX is short for what?

    Hehe, it's a trick question. UNIX is not an acronym therefore does not short for anything. An early versions of UNIX was actually called UNICS and it was short for UNiplexed Information and Computing Service. Additional information about UNIX can be found on this page.

    Here's a little history info. on UNIX
    This information and more can be viewed
    here.

    Year | Event

    1957 - Bell Labs found they needed an operating system for their computer center which at the time was running various batch jobs. The BESYS operating system was created at Bell Labs to deal with these needs.

    1965 - Bell Labs was adopting third generation computer equipment and decided to join forces with General Electric and MIT to create Multrics (Multiplexed Information and Computing Service).
    1969- By April 1969, AT&T made a decision to withdraw Multrics and go with GECOS. When Multrics was withdrawn Ken Thompson and Dennis Ritchie needed to rewrite an operating system in order to play space travel on another smaller machine (a DEC PDP-7 [Programmed Data Processor 4K memory for user programs). The result was a system which a punning colleague caled UNICS (UNiplexed Information and Computing Service)--an 'emasculated Multrics'.
    1969 - Summer 1969 UNIX was developed.

    1971- First edition of UNIX released 11/03/1971. The first edition of the "UNIX PROGRAMMER'S MANUAL [by] K. Thompson [and] D. M. Ritchie" is also dated "November 3, 1971". It includes over 60 commands like: b (compile B program); boot (reboot system); cat (concatenate files); chdir (change working directory); chmod (change access mode); chown (change owner); cp (copy file); ls (list directory contents); mv (move or rename file); roff (run off text); wc (get word count); who (who is one the system). The main thing missing was pipes.
    1972- Second edition of UNIX released 12/06/1972
    1972- Ritchie rewrote B and called the new language C.
    1973- UNIX had been installed on 16 sites (all within AT&T/Western Electric); it was publically unveiled at a conference in October.

    Some more information about UNICS a.k.a. UNIX :-).

    Unix is a "play on words" of an older multi user time-sharing OS known as Multics. UNIX was also originally designed as a single user environment (hence "U"nix).

    Nice post Remote_Access_ , the history has a lot to tell us about the future !!

    Very informative post. Somene just posted a request for historical information a couple nights ago. Hope he sees this one.

    Thumbs up

    ...and when they make a multi-
    user version, it will be called WENIX
    I came in to the world with nothing. I still have most of it.

    Well, the name was actually given by Dennis Ritchie. He took the name from the japanese Eunucs, saying that Unics was a Multiplex castrated OS.

    They used to have a lot of fun there in AT&T!!!!!. They used to leave the computers log as root. Pizza 3 weeks old and cables all around the floor!!, nice environment!!!.

    Lightbulb UNIX

    This is what my dictionary states for UNIX:

    n. Operating System which can operate on various computers and support multi-tasking
    This is what my dictionary states for Windows:

    n. Interface, computerized work environment.


    Hmmm... Which do you think Babylon Dictionary prefers? Due to the thorough description of each...

    ...This Space For Rent.

    I guess this is all bout the famous flaming war or maybe someone has something against newbies as the text below so nicely told me :-).

    Remote_Access_ is not what you think. He randomly copied other peoples work and claimed it as his own. It's newbies like you that have no idea and come here and say "nice work RA that ruin it for everyone else
    Since no name was added to the antipoints "unknown" gave me have I to make myself clear and post it here.

    I see nothing wrong in copy and past as long as the source is stated. And what I can see in RA's post is the source clearly stated (as a link). And it happened to be a nice post since the history often are forgotten these days when all new inventions and the evolution of the computer market is so fast! In this case is my words "nice work" not for the reasearch but for bringing a lost era up to the surface !!

    And I don't give a thing for the flaming war here at AO and that several people has a major war going on. I'm a newbie to this board but not in the field of security. I'm here for education and even bring some wisdom words to this board now and then, not to attend in a war !! .

    Kind regards to all here at AO
