&lt;br /&gt;<br /><br />
&lt;br /&gt;<br /><br />
Sorry, but this is not the way that works.&lt;br /&gt;<br /><br />
&lt;br /&gt;<br /><br />
First: you come across like a teacher posing the homework for us. Actually we are all professionals here and have done our homework meticulously which is why we don't have to do more homework any more. In case it was homework given to &lt;i&gt;you&lt;/i&gt; by &lt;i&gt;your&lt;/i&gt; teacher: there is a special forum for this with special rules in place. Please re-create the thread there and provide the necessary information.&lt;br /&gt;<br /><br />
&lt;br /&gt;<br /><br />
Second, in case this is not homework but actually your work: we do not insist on a lot of social conventions here (after all, we are sysadmins - being somewhat autistic is part of the requirement for this job), but still a well-placed &amp;quot;please&amp;quot; here and there, along with some of the common niceties called &amp;quot;good manners&amp;quot; oils the social machinery. If you ever wonder who writes the answers to your questions: it is not some clever machine and a fat server - it is actually living, breathing persons.&lt;br /&gt;<br /><br />
&lt;br /&gt;<br /><br />
Third and foremost: we are here to help you help yourself. If you want a shell-script - WRITE IT! Attempts, however failing, will count. If you tried and it didn't work, post what you did and the error you got trying to run it. We will, regardless of how long it will take, explain to you what was wrong and how to do it better (actually quite like the way i explain to you right now why you need to change your problem statement) until you understand. We will also point out ways to better solve the problem, different tools, suggest sources to find valuable information and so on and so on. But we will NOT write your code for you. We are a help forum, not your unpaid programming staff.&lt;br /&gt;<br /><br />
&lt;br /&gt;<br /><br />
I hope this helps.&lt;br /&gt;<br /><br />
