I’ve just released a report on the size of Red Hat Linux
version 6.2’s source code. Interesting results include the
following:
- This Linux distribution includes well over 17 million physical
source lines of code (SLOC). - Over 4,500 person-years of development time would have been
required to build this distribution by conventional proprietary
means. - It would have cost over $600 million (in year 2000 dollars) to
develop this distribution in the U.S. using conventional
proprietary means.
The largest components (in order) were the linux kernel, the
X-windows server, egcs, and emacs. The languages with the most
lines of code were (in order): C, C++, LISP, shell, and perl; many
other languages were also represented.
