Trace of the code with last screenshot

rm -rf student-submission

removed the folder student-submission

mkdir student-submission

crate a new folder named student-submission

git clone $1 student-submission

clones the linked github repository into the folder named student-submission in this line standard error “Cloning into ‘student-submission’…” is printed

cp TestListExamples.java student-submission

copies the TestListExamples.java file into the student-submission folder

cd stduent-submission

changes current directory to student-submission folder

GRADE=0

creates variable named GRADE and equal to 0 to trace the grade

if [[ -e ListExamples.java ]]

checks if the ListExmaples.java file exists. In this case, the file exists. Condition is true. So it goes to the then statement and echo "ListExamples.java file submitted! +1 point" by standard output and increments GRADE by ((GRADE++)).

else echo "ListExamples.java file is missing -1 point Total: " $GRADE"/3 point" exit 1 fi

these lines are not runned because the if condition was true.

CPATH:".:../lib/hamcrest-core-1.3.jar:../lib/junit-4.13.2.jar"

variable CPATH created to make javac and java command easiler

javac -cp $CPATH *.java

complie the java files and because this file returns the complie error, it printed the standard error.

if [[ $? -eq 0 ]]

checks if complie was successful but the condition is false because there was complie error.

then echo "Files are successfully complied! +1 point" (GRADE++)

these lines are not runned because the if statement was false.

else echo "Complie Error -1 point Total:" $GRADE"/3 point"

this line is runned because the condition of if statement was false. It echo “Complie Error -1 point Total:” $GRADE”/3 point” with standard output.

exit 1

return code was non-zero and all of the line after this line is not runned because this is an early exit.
