Shell Programming and Scripting

I'm trying to write a script that can compile my students' homework submissions in bulk. My students' c code is buried in a file path that looks like this:
./Homework\ X/Doe, John/Submission\ Attachments

Where I'm struggling is determining how to navigate to each of the submission attachment directories so I can compile their code.

I'd like my script to be as simple as typing in the name of the Homework directory and the makefile path, and having the script take care of the rest.

How to compile them really depends on what they are. Unless they use makefiles, I can't think of a good all-in-one solution. Even if they do use makefiles, they'd have to all write them the same way.

Compiling isn't the issue. What I need is a way to navigate to each of the 'Submission Attachment' folders, without letting the computer know the names of all the students in advance. The directories with the students names are the only directories inside 'Homework X'.

Oh, that's simple enough.

Code:

#!/bin/sh

for DIR in "/path/to/Homework X"/*
do
        [ -d "$DIR" ] || continue # Ignore non-folders

        echo "Do stuff with $DIR"
done

Thanks! I'll try that out.

I've run into an error message I do not understand:

./autograder2.sh: line 2: $'\r': command not found
./autograder2.sh: line 4: syntax error near unexpected token `$'do\r''
'/autograder2.sh: line 4: `do

What does this mean?

It means, don't edit your scripts in Microsoft Notepad. Edit them in a UNIX text editor of some sort, to prevent Windows from filling them with useless carriage returns.

Ah, ok. Thank you. I was using notepad++. I'm using cygwin to emulate linux.
