Hello Harshit, > Replace 'test -f' with the helper function 'test_path_is_file' as the helper function improves the code readability and also gives better error messages. Again the same thing, you may follow what I stated before regarding commit messages. The commit title can be of the form: t4131: use helpers to replace test -f <path> <<commit description>> If you still face any problem, feel free to drop a message :) Regards, Shourya Shukla
