History of Unix & Linux


YearEvent
1957Bell Labs found they needed an operating system for their computer
center that at the time was running various batch jobs.
The BESYS operating system was created at Bell Labs to deal
with these needs.
1965Bell Labs was adopting third generation computer equipment and
decided to join forces with General Electric and MIT to
create Multics (Multiplexed Information and Computing Service).
1969By April 1969, AT&T made a decision to withdraw Multics and go
with GECOS. When Multics was withdrawn Ken Thompson and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 that a punning colleague called UNICS
 (UNiplexed Information and Computing Service)--an 'emasculated
 Multics'.
1969Summer 1969 Unix was developed.
1969Linus Torvalds is born.
1971First edition of Unix released 11/03/1971. The first edition of the
"Unix PROGRAMMER'S MANUAL [by] K. Thompson [and]
D. M. Ritchie." 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.
1972Second edition of Unix released December 06, 1972.
1972Ritchie rewrote B and called the new language C.
