Use the command turnin to submit your project. Its usage is:
turnin --submit <grader> <assignment-name> <file1> <file2> ...
For this course one of the graders is tmtorres. The assignment names will be cs378pj1 for Project #1, cs378pj2 for Project #2, and so on.
Whenever you submit a file, it gets time stamped.
You can see whether the submission was successful or not by giving the following command:
turnin --list <grader> <assignment-name>
This will show the list of files which got submitted.
If you want to submit the text file Collatz.zip for Project #1: Collatz, then, give the following command:
turnin --submit tmtorres cs378pj1 Collatz.zip
turnin --list tmtorres cs378pj1
turnin --verify tmtorres cs378pj1
If you submit a file a second time, then the previous file and its time stamp will get overwritten. Once submitted, you can not undo your submission (although you can overwrite any file).
Type man turnin on any department Unix machine (press space to page forward and q to quit).
