The e glob qualifier -  e.g. to match all files of which file
says that they are JPEGs:
</p>



<pre class="example">% ls *(e:'file $REPLY | grep -q JPEG':)
</pre>



<ul>
<li>(#s) or (#e) for what ^ and $ are in regexps (beginning of line/end of line)
</li>
<li>(#b) or (#m) to enable backreferences
</li>
<li>(#i) to match case insensitive
</li>
<li>(#a) to match approximately (certain errors are ignored, e.g. "(#a1)foo*" matches the string "ofobar")
</li>
</ul>


<p>
Tip: run e.g. `ls *(&lt;tab&gt;` to get help regarding globbing.
