Well, regardless, without UNIX I seriously doubt LINUX would look and feel anything like it does today. There are obvious influences from UNIX that can be felt and seen in POSIX. GNU draws a lot of influence from the UNIX commands as well (is GNU's 'ls' much different from UNIX 'ls'?). On would be hard pressed to argue that the GNU commands operating differently then the UNIX counterparts. All that said if you want to get a feel for UNIX architecture I would suggest going straight to the source that is, thankfully, presented by one of the two fathers of UNIX on the Internet free of charge. Dennis Ritchie has published a number of early papers on his personal Bell Labs website that give a great feel for where a lot of the commands originated and how early UNIX was created. Check out the following: Dennis Ritchie's Bell Labs home page: http://cm.bell-labs.com/cm/cs/who/dmr/ Unix Programmer's Manual, First Edition 1971: http://cm.bell-labs.com/cm/cs/who/dmr/1stEdman.html Ritchie's 1972 notes on UNIX: http://cm.bell-labs.com/cm/cs/who/dmr/notes.html How the pipe originated: http://cm.bell-labs.com/cm/cs/who/dmr/mdmpipe.html And, finally, the Unix Hater's Handbook (don't get too bent out of shape that it is hosted on a Microsoft webpage, the person who posted this is a UNIX hack from way, way back) http://research.microsoft.com/~daniel/preface.html There is a wealth of knowledge on Mr. Ritchie's home page for anyone interested.
