<h2 class="title"><a name="shell">Interacting with the Shell</a></h2>
<div class="content">
<p>
Certain characters are interpreted by the shell. For example, the
"&amp;". If you wish to include the &amp; in a task description,
you need to escape it, so the shell doesn't interpret it. For
example:
</p>
<pre><code>% task add Buy bread &amp; milk</code></pre>
<p>
This command is an error because of the &amp;. The shell will
consider this to be two commands:
</p>
<pre><code>% task add Buy bread &amp;
% milk</code></pre>
<p>
The shell treats the &amp; character as an indicator that the
command is complete and should be run in the background. Then the
shell considers "milk" to be a command all by itself. Which it is
not. One way to get around this is to individually escape the &amp;
character:
</p>
<pre><code>% task add Buy bread \&amp; milk</code></pre>
<p>
Another is to quote the entire description, with either ' or "
characters:
</p>
<pre><code>% task add "Buy bread &amp; milk"</code></pre>
<p>
Task itself interprets the commands, and it too can make mistakes.
For example, any colon : character will be interpreted by task as a
delimiter between an attribute name and its value. Currently there
is no workaround for this.
