+Reflection Essay:
+Through this lab,
+1. We enjoyed coding this much for the first time! Every task had a charm as to which pokemon were we going to catch this time.
+2. Learned how to code up the solutions for problems related with a large numbers of files using shell scripts.
+3. Learned how to use regex for finding strings with a particular condition.
+4. Learned how to share files via terminal. (File transfer using ncat)
+5. Learned how to login to a site using curl.
+6. Learned how to get a file type without looking at its extention (which are misleading sometimes)
+7. Came to know we can restrict the login to the page to some methods by changing some code at the server side(like the one done in Part D of this Lab)
