David A. Wheeler studied the [[Red Hat]] distribution of the [[Linux|Linux operating system]], and reported that Red Hat Linux version 7.1<ref name = "Wheeler-RH7.1">{{cite web |date=2001-06-30 |url=http://www.dwheeler.com/sloc/redhat71-v1/redhat71sloc.html |author=David A. Wheeler |title=More Than a Gigabuck: Estimating GNU/Linux's Size }}</ref> (released April 2001) contained over 30 million physical SLOC. He also extrapolated that, had it been developed by conventional proprietary means, it would have required about 8,000 person-years of development effort and would have cost over $1 billion (in year 2000 U.S. dollars).

A similar study was later made of [[Debian GNU/Linux]] version 2.2 (also known as "Potato"); this operating system was originally released in August 2000. This study found that Debian GNU/Linux 2.2 included over 55 million SLOC, and if developed in a conventional proprietary way would have required 14,005 person-years and cost US$1.9 billion to develop. Later runs of the tools used report that the following release of Debian had 104 million SLOC, and {{As of|2005|alt=as of year 2005}}, the newest release is going to include over 213 million SLOC.
