-
-A very useful feature for scripting is loops; that is, the ability to write a repeating piece of code.<br>
-Loops take this form:
-<pre>
-  [condition] do
-    [repeated code]
-  done
-</pre>
-
-
-In particular, there are two types of loops, for loops and while loops.<br>
-For loops are written like this:
-<pre>
-  for [variable] in [list] do
-    [code]
-  done
-</pre>
-Their function is to <i>iterate</i> over a list. The list can take various forms, but the variable will always be
-one of its elements. In particular, it will be the first element of the list on the first iteration and advance by
-one element in every iteration after that. Most importantly, it can be accessed from inside the repeating code.<br>
-<br>
-The most basic kind of list is a numerical range, written like this:
-<pre>
-  for i in {1..10}; do
-    [code]
-  done
-</pre>
-<code>{1..10}</code> means "the list of every number between 1 and 10 (inclusive)".
-<code>i</code> is the variable that will hold one of these numbers in every iteration.
-Here's a simple example of how to use it:
-<pre>
-  for i in {1..10}; do
-    echo $i;
-  done
-</pre>
-<!-- TODO: insert the correct link here once the variables page is up -->
-<a href="#"><code>$i</code> is how you access the variable i</a>.
-Ranges can also count backward like this: <code>{10..1}</code>.
-Another way to say what <code>{1..10}</code> means is "The numbers between 10 and 1, <i>in increments of 1</i>".
-What if you want increments of two, though? What if you want every <i>even</i> number in a range?<br>
-Numerical ranges also allow you to specify the size of the increments or decrements between each element in the list,
-more generally called the <i>step size</i>.
-Here's an example:
-<pre>
-  for i in {0..10..2}; do
-    echo $i;
-  done
-</pre>
