Linux Operating System history starts from Bell labs in 1957. They were needed an operating system to run batch jobs. They created BESYS operating system to deal with it. This was replaced by Multics(Multiplexed Information and Computing Services).
Later in 1969, Dennis Ritchie and Ken Thompson had rewrite an operating system, that led to UNICS (UNiplexed Inforamtion and Computing Services) ----- an 'emasculated Multics'.
In summer of 1969 Unix was developed.
First edition of Unix was released in 1971. It includes 60 commands like cat, chdir, chmod, chown, mv, ls, cp etc. But it was lacking piping.
In this duration, Dennis Ritchie rewrote B and created new language C.
And Unix was written in C.
In October 1973, Unix released publicly in a conference and installed at 16 sites.
In next two decades various distribution of Unix launched like BSD, SCO, IRIX, System V, HP-UX, IBM-AIX, Sun Solaris etc.
In 1991, Linux was introduced by Linus Torwalds, as a student in Finland.
Later various flavors of Linux came in market i.e RedHat, Fedora, Ubuntu etc.
In my next post I will summarize the various shell version and their incorporation with Unix.
till then have a nice time and learn LinuxWithEase. smile :)
