<p>As a simple example, I want to write a CLI script which can print <code>=</code> across the entire width of the terminal window.</p>

<pre><code>#!/usr/bin/env php
&lt;?php
echo str_repeat('=', ???);
</code></pre>

<p>or</p>

<pre><code>#!/usr/bin/env python
print '=' * ???
</code></pre>

<p>or</p>

<pre><code>#!/usr/bin/env bash
x=0
while [ $x -lt ??? ]; do echo -n '='; let x=$x+1 done; echo
</code></pre>
