CSC552 Fall 2015 week 1 outline Parson, UNIX, and so forth

Chapter 1 stuff UNIX has been around for a while (since ‘69). It started in Bell Labs as a skunk works project. It has many variants. Research versions, Berkeley System Distribution, SunOS / Solaris, AT&T System V, Mach, Mac OSX, Linux flavors. We will concentrate on system calls & utilities that are “universal,” especially according to POSIX standards. The textbook came out in The system calls haven’ changed (much). Linux & bash are more prominent (no problem). Otherwise, the big changes build atop the UNIX base.
