Here are some shell work to be done.  You get 5 points if you finish one of them, 9 points if you finish 2, 12 points if you finish 3, 14 points if you finish 4, and 15 points if you get them all. You can and <b>should</b> do them in order easiest to hardest.  You can use any reasonable format, and don't have to stick the the format below.

<p>1) Change your prompt including at least 2 special codes.  Crazy ideas can be found <a href=http://gilesorr.com/bashprompt/prompts/>here</a> and the list of codes can be found <a href=http://gilesorr.com/bashprompt/howto/x186.html>here</a>.<br>


<p>2) Write me a shell script that sends mail to any user who's home directory is world writeable.  Print and send email to any such person.
<pre>
	biden
	obama
	chaney
</pre>



3) Write a script that checks that for every directory inside of /home, that person also exists in /etc/passwd and in /etc/shadow.  Print any such person.
<pre>
	biden
	obama
	chaney
</pre>


4) Write me a script that lists every *.iso and *.ISO file on the system.<br>
Sample Output:
<pre>
	/home/palin/movie-of-biden.iso
	/home/obama/kids-at-play.ISO
	/home/bush/Advice/advice-from-Nixon.ISO
</pre>



5) Write me a script that lists everyone who has logged in and how many times thay have logged in.  The last command might be useful.  <br>
Example Sample Output:<br>
<pre>
	palin   27
	biden   3
	bush    23
        chaney  5
</pre>
