Programs

The first program, Shell, is similar to the CS33 project. It's an optional assignment for students who did not take CS33 and/or could use a C refresher.

As mentioned above, for Weenix projects (VFS and S5FS) we will not post individual PDFs; for each project, please see the corresponding section in the weenix documentation PDF. Also, the Introduction section and Appendices B and C are useful in general.

Note that all sections are out on Jan 30 and there is one due date on May 9 for the whole project. The dates for each section are the recommended start and end dates, given the relative sizes of each section.
