This exercise will test your ability to follow instructions, work with code, use the unix/linux command line and your problem solving capabilities. You can look up answers on the internet to help you using google, documentation, tutorials, etc.

• Open the file links.html in a web browser. You'll see a link but that doesn't work when you click on it.
• Open that same file in your text editor and fix the link so that it goes to google the way its supposed to.

• Open the file iframe_ad.html in a web browser. It should display an ad, but it's currently broken.
• Open it in a text editor. You'll notice it uses the html "iframe" tag.
• Fix the iframe so that the ad displays.

• Grep is a linux/unix command that lets you search text from a terminal. As an example, open the mac terminal and type in the following command:

grep "/ads/200744/" ads.log > results.log

• This command will have searched the file ads.log, found all the lines that contain the text "/ads/200744/" in them and put the matches in a file called "results.log"
• The "/ads/200744/" is the pattern to search for, the "ads.log" is the file to search and the " > results.log" takes the matching lines that grep found and stores them in a file call results.log.
• The number 197339 in the search above is one of our "campaign ids" that signify what campaign the ad ran under.
• Run the same command, but with some minor changes: Use the campaign id: 198680 instead of 200744 and put the results in a file called results2.log
