Submit script
The submit
script is a program used on UNLV CS servers for students to submit assignments to instructors. It is more common to use it in required introductory CS courses such as CS 135, although instructors may opt to use alternate submission methods such as email, WebCampus, or Moodle). Be sure to follow the assignment submission policies as provided by your instructor in class and on the syllabus.

script instructions
- SSH to
bobby.cs.unlv.edu
and log in- You cannot submit your programs directly from lab computers in TBE B-361, you must SSH into
bobby
first - If
bobby
is not available, trycardiac.cs.unlv.edu
orjava.cs.unlv.edu
- You cannot submit your programs directly from lab computers in TBE B-361, you must SSH into
- Navigate to the directory your file is located in
- Make sure your program compiles, is documented, and is tested
- Type the following:
submit filename XX instructor
-
filename
is the name of your file (e.g.asst1.cpp
) -
XX
is the assignment code and can range from 01 to 30, inclusive (note: the leading 0 is important -- 04 is correct, 4 is not correct) -
instructor
is the login name of your instructor -- you can see a current list of instructors and usage tips by typingsubmit
without any other text

- Check below for examples of correct and incorrect submissions as well as output from the script, but note that your file is received by the instructor only when you receive the message
file Successfully Submitted!
Notes about submitting
- You should only submit
.cpp
or.tar
files- The script will only successfully submit text files (e.g. submitting
a.out
would not be allowed) or binary files with.tar
extension - For more information see the page on tar files, but note that these would only typically be used when multiple files are required for an assignment
- The script will only successfully submit text files (e.g. submitting
- Your file is time stamped and the instructor will download all student submitted files at once by specifying the assignment number and the last time stamp to accept
- If your submission is due by 11:59 PM, you submit it at 12:03 AM, and your instructor downloads all submissions that are no later than 11:59 PM then your instructor will not get your submission
- If your submission is for assignment 05 but you submit it with assignment code 06 then your instructor will not get your submission
- You may submit as many times as you like although typically only the last submission prior to the deadline is downloaded by the instructor
- The name of the file you submit does not matter -- when an instructor downloads your submission the file is renamed, although if you are submitting a
.tar
file the paths and filenames within are not modified

Example submissions
Correct .cpp
submission
[username@bobby directory]$ submit file.cpp 01 instructor
dos2unix: converting file /opt/submit/tmp_instructor/username.01.20180112160154 to Unix format ...
file.cpp Successfully Submitted!
Note the presence of a filename, a valid assignment code (01, not 1), and the instructor's name. You would replace file.cpp
, 01
, and instructor
as appropriate.
The dos2unix
message is in reference to a program that is run to correct differences in character sets between Windows and Linux. The message Successfully Submitted
indicates that the program was submitted successfully.
Correct .tar
submission
[username@bobby directory]$ submit file.tar 01 instructor
dos2unix: Binary symbol found at line 1
dos2unix: Skipping binary file /opt/submit/tmp_instructor/username.01.20180112161209
file.tar Successfully Submitted!
The message indicating skipping the file refers to the fact that there is no reason for dos2unix
to correct character set differences in a binary file. The message Successfully Submitted
indicates that the program was submitted successfully.
Invalid filename
[username@bobby directory]$ submit fakefile.cpp 01 instructor
File Not Found!, Submit Failed!
Please specify a valid filename in the current directory
and submit again.
Invalid .tgz
submission
[username@bobby directory]$ submit file.tgz 01 instructor

and submit again.
.tar
files are the only binary files that the submit script will accept.
Instructor notes
Use getsubmit
to see usage details on how to download student submissions and filter by assignment number and time stamp. Even after using getsubmit
, all student submissions remain in ~/submit
until you manually move or remove them.
When downloaded using getsubmit
only the last submitted file prior to the time stamp you specify will be downloaded. All files, including .tar
files, will download to the current directory as username.cpp
.
