			== egrep ==

			If you have a complex search term, you can use [[Regular Expressions]] with egrep.

			Usage:

			egrep 'Regular Expression here' filename.txt

			Like this:

			<code>egrep '[aeiou]{3,}' filename.txt</code>

			This will find any three vowels that are right next to each other in filename.txt
			You can put any [[Regular Expressions]] inside the single quotes.

			== Show Line Numbers ==

			You can make grep show the numbers the match is on:

			<code>grep -n candy candylist.txt</code>

			This will show the number of the line the match is on, like this:

			<pre>
			5: candycanes
			18: cotton candy is yummy, too
			42: Candy bars:
			</pre>

			This is very convenient when you're greping for something, and want to edit that line in the file in [[vim]]

			If you want it to find all of those, use:

			<code>grep -i bananas filename.txt</code>
