Grading scripts for CS50 problem sets

Grade50

Bash scripts to help with the grading of CS50 problem sets. Feel free to PR with alternatives.

Usage

Get and set up the repo:

update50
git clone https://github.com/raphaelrk/grade50.git
cd grade50
find . -type f -name "*.sh" -exec chmod 777 {} \;

Use the scripts:

cd pset4
./retrieval.sh
./grade_all.sh
./bmp_grade_all.sh # specific to pset 4

Update the repo:

update50
cd grade50
git pull
find . -type f -name "*.sh" -exec chmod 777 {} \;

What the scripts do:

• ./retrieval.sh retrieves pset submissions and combines them into per-student folders, i.e. grade50/pset4/briansmith/resize.c, grade50/pset4/briansmith/recover.c, etc
• Grade an individual folder by cd-ing into it and running ../grade.sh, which'll both output to stdout and to a file called check50.txt in the student's folder
• Grade all the folders in your pset's directory at once with ./grade_all.sh

grade50's Issues

Timeouts

check50 has timeout functionality built into it for code that, for example, contains an infinite loop. However, the ps5 grade_all.sh also runs valgrind on student code. valgrind does not automatically timeout for programs that never exit. Because of this (especially for less-comfortable sections), I would recommend running all non-check50 commands processing student code with something along the lines of timeout 60s <CMD> <ARGS>.

Seems like ownership still hasn't transferred, would like for it to be under my name if possible :)
