If you have used these 2 before: git config user.email <"you@augustana.edu"
and git config user.name <"YOUR NAME">, you shouldn't have to type in your git credentials every time. You can just start your git bash with: cd <your/file/location>. You can check lab 2 step b 8 for further explanation of how to set up your git bash to not ask for your credentials every time. If you are using lab computers, you may have to enter your credential once but on your laptop, you don't have to every single time.
Also, if your git bash is stuck, try typing "q" and enter to exit. I hope I understood your question and I hope this helps!!
