Operating Systems The best way to predict the future … is to I N V E N T I T!!! Alan Kay, inventor of SmallTalk, 2004 ACM Turing Award

Let ’ s start by inventing … A SHELL just like command.com in MSDOS, or cmd in MS Windows, or tcsh in Linux This is a “ qualification exam ” for this course!!!

Shell A shell program can Accept commands Interpret commands Execute commands Display results of execution

Shell Programming Environment OS: Linux Compiler: gcc, g++, or any Java compiler Required commands help or h (shows a list of commands), help (shows detailed help on ), quit, q, exit, e, ! (escape character, e.g., !ls, i.e., escape to outer execution environment to execute “ ls ” )

Shell Optional commands 2 + 3, … like a calculator run test1, test2, … a shell for your future projects a text-based user interface for some kind of software tool could be menu-driven

Shell Form a group of 2 persons Hand-in list by 9/20 Deliverables source code documentation (code architecture, features, user guide, reference manual, etc.) compiled executable (virus-checked) if you submit a virus, you will get 0 points Archive all the above into a zip file

Shell Deadline September 27 zip file to Demo will be scheduled later by TA Please go to html to get the latest information html
