When you have completed your assignment, you will run the submit program to submit the appropriate directory. For example, to submit your solution to homework 3:
Course (22C:016 would be c016): c021 Possible submit directories for /group/submit/c021 are: homework3 Choice: homework3
* File/directory homework3 has been * copied to /group/submit/c021/homework3/homework3.jane.
Note that you can resubmit an assignment, but the new submission overwrites the old submission and receives a new timestamp.
