=====Purpose=====
The purpose here is to mine the 2012 spring class schedule in html format and extract specific classes

=====Necessities=====
  * Knowledge of Regular Expressions
  * Knowledge of Shell Scripting

=====Process=====
  * With this I will be saving the relevant data to a file and manipulating the file via a shell script.

=====Things=====

  * To get the dataz
<cli>
  * cat spring2012-20111103.html | grep "ddtitle" | sed 's/^<TH CLASS="ddtitle".*crn_in=.....">//g' | sed 's/<\/A.*$//g' | sed 's/^\(.*\) - \([0-9][0-9][0-9][0-9][0-9]\) - \(.*\) - \([0-9][0-9][0-9]\)$/\1: \3-\4:\2/g'
</cli>


  * Shell Script
<code>
#!/bin/bash

echo -n "please enter a class: "

read class

cat combooutput1 | grep -A5 $class
</code>

=====Attributes=====
  * Files and directories
  * Commands
  * The UNIX shell
  * Regular Expressions
  * Filters
  * Scripting
  * The UNIX development Environment
=====Final Thinkings=====
  * This was relatively easy working with only the necessary data.
