Work the Shell - Simple Scripts to Sophisticated HTML Forms
Let's look at a more interesting subset, instead, by adding a -c flag to have it output just a count of how many films match the specified criteria, you've given the command instead.
To do that, we don't need to go page by page, but just identify and extract the value from the match count on the page. For the comedies with “funny” in the title, the line on the page looks like this: “< Prev | 1 - 20 of 37 | Next 17 >”.
What we need to do is crack the HTML and look at the source to the link to “next 17” and see if it's extractable (is that a word?):
./findmovie.sh -d -g com funny | grep -i "next 17" | head -1 <td align=right><font face=arial size="-2"><nobr> ↪< Prev | <b>1 - 20</b> ↪ of <b>37</b> | <span ↪class="yperlink"><ai href="/mv/search?p=funny&yr=all ↪&gen=com\&syn_match=all&adv=y&type=feature ↪&n=17&b=21&h=s">Next 17</a> > ↪ </nobr></span></span></font></td></tr>
Well that's ugly. You'd think Yahoo didn't want to make this easy or something! It turns out though that this is a pretty tricky task, because if there are no matches, the link doesn't show up, and instead you see “Sorry, no matches were found”. If there are less than 20 matches, you see “Next >”, but it's not a clickable link, so it's not going to be so easy!
Given that I'm out of space, let's defer this topic until next month. Meanwhile, look at the source to various searches yourself and see if anything comes to mind. Otherwise, it'll be brute force!

Getting Started with DevOps - Including New Data on IT Performance from Puppet Labs 2015 State of DevOps Report

DevOps represents a profound change from the way most IT departments have traditionally worked: from siloed teams and high-anxiety releases to everyone collaborating on uneventful and more frequent releases of higher-quality code. It doesn't matter how large or small an organization is, or even whether it's historically slow moving or risk averse — there are ways to adopt DevOps sanely, and get measurable results in just weeks.
