1) Go to directory
		/home/tsrk/Desktop/compiler_revaluation

2) from terminal, execute the command
	timeout -k 0.5 5 nodejs compiler.js -l lab1 -i 2014A7PS001G -h 6d4014b5 --lang c --host 'localhost:9000' >> scores.txt

	write a shell script for loop to iterate over all the students

3) To get all commit hashes of a repository
	git log --pretty=format:"%h"

4) to cache git credentials so that you don't have to enter the password repeatedly
		git config --set credential.helper 'cache --timeout=600'

5) to clone a repository
		git clone "https://localhost/$student_id/lab1.git"

Algorithm:
		cache git credentials										git config --set credential.helper 'cache --timeout=600'
		For each student
				clone the repository								git clone "https://localhost/$student_id/lab1.git"
				get all the commit hashes							commits=$(git log --pretty=format:"%h")
				evaluate for all commit hashes of the student		timeout -k 0.5 5 nodejs compiler.js -l lab1 -i 2014A7PS001G -h 6d4014b5 --lang c --host 'localhost:9000' >> scores.txt
