Homework 3 on Using Grep

As I indicated in class, wget will not get the page you need for this homework. Download the displayed page manually (which is dynamically generated) unless you know how to find the correct URL using analyzers such as charles or whichever you are familiar with.

For those live videos or movies that do not have all five fields, you can let them go for now. Collect data as much as you can. We'll come back with a sophisticated air-tight method that can handle all these abberations, outliers, missign cases, etc. Again, as I said in class, this is just for a quick way of checking, rapid-prototyping if something can be done with a minimal effort. Then and only then can you make a decision on whether to proceed futher.

What to submit:

  1. execute expr-based script, display a CSV table, take a screenshot of command execution and the table
  2. repeat 1 using grep-based script
  3. repeat 1 using a one-liner sed
  4. prep a tgz file of three source code/scripts and three screenshots
Do not include the html file.
