Once upon a time, Unix was very small and fit entirely in what is now the root filesystem, / ; hence, among other things, /bin , which was where commands went. This didn't last very long, and by the time of at least the Third Edition in 1973, there was an additional /usr filesystem with a /usr/bin for 'overflow' programs that didn't fit on the root filesystem any more. (As I heard the story, the root filesystem was deliberately set up to contain everything you needed to rebuild at least the kernel, in case you booted a kernel that couldn't mount the user filesystem. Hence as late as V7 Unix you could find the C compiler as /bin/cc and so on.)
Note! This site is about Perl 6 , the future version of Perl. If you are looking for a solution for the current production version of Perl 5, please check out the Perl 5 tutorial . This Perl 6 Tutorial is based on the training material used by me (Gabor Szabo) to teach Perl 6 in various training classes. It is a work in progress.
Perl 6 is the sixth edition of the Perl programming language, representing a major backwards-incompatible rewrite of the language. It's a versatile and powerful multi-paradigm programming language. This book is going to introduce the reader to the Perl 6 language and its many features. Introduction
