It is practically impossible to teach good programming style to students that have had prior exposure to Basic; as potential programmers they are mentally mutilated beyond hope of regeneration.

This is one that was driving me crazy - couldn't find it anywhere on the net:
DELETE ALL LINES BETWEEN TWO MARKER PATTERNS (but not the markers themselves):
e.g. in a hosts file
== /etc/hosts ==
192.168.1.2 host1 192.168.1.3 host2
### START ### #delete 192.168.1.4 host3 #delete 192.168.1.5 host4 #delete #delete ### END ###
192.168.1.6 host5
=============================
The money:
sed -i -e '1,/^### START ###/!{ /^### END ###/,/^### START ###/!d; }' /etc/hosts
I have no idea how it works, but it does. Now your markers are preserved for you to insert other stuff with your funky automation scripts.
sed -i -e '/^### START ###/,/^### END ###/{//!d;}'

E-mail: (why do I need your e-mail?)
It would be nice if you left your e-mail address. Sometimes I want to send a private message, or just thank for the great comment. Having your e-mail really helps.
I will never ever spam you.

Website:
* use <pre>...</pre> to insert a plain code snippet.
<pre>...</pre>
* use <pre lang="lang">...</pre> to insert a syntax highlighted code snippet. For example, <pre lang="python">...</pre> will insert Python highlighted code.
<pre lang="lang">...</pre>
<pre lang="python">...</pre>
* use <code>...</code> to highlight a variable or a single shell command.
<code>...</code>
* use <a href="url" nospam>title</a> to insert links.
<a href="url" nospam>title</a>
* use other HTML tags, such as, <b>, <i>, <blockquote>, <sup>, <sub> for text formatting.
