I have been searching two minutes:

http://www.google.co.uk/search?q=ls+source+code

returns as the top search result a link to:

http://en.wikipedia.org/wiki/Ls

Which contains an obvious link to:

http://minnie.tuhs.org/UnixTree/V7/usr/src/cmd/ls.c.html

Among the other top 10 google search results were several instances of 
people asking the same question.

This is a friendly list, but please don't abuse people's goodwill by 
asking questions without doing some basic research first - especially if 
those questions do not relate to ruby.
