Inspired by Tanenbaum and Minix, Torvalds developed his own UNIX clone
in 1991, which he dubbed Linux. Now, this first version of Linux was extremely
minimal in nature. It wasn??™t a full-blown operating system complete with
applications and utilities. Instead, Linux version 0.02, released on October 5, 1991,
consisted of only the Linux kernel and three utilities:
?– bash A command-line interface
?– update A utility for flushing file system buffers
?– gcc A C++ compiler
In an unprecedented move, Torvalds posted the source code for his Linux
operating system on the Internet and made it freely available to anyone who wanted
to download it. The corporate software development model had been completely
broken.
Torvalds took things one step further and invited other programmers to take
the Linux source code and enhance it. Linux took on a life of its own and became
a worldwide collaborative development project. No secrecy; no tightly guarded
copyrights. Access to the Linux source code was open to anyone who wanted it.
This collaborative development project on Linux continued for several years. In
1994, Linux version 1.0 was ready for release. The results since have been nothing
short of amazing.
