In this tutorial, you will learn how to use regular expressions to search files
for text patterns, how to locate files on your system, and how to take full
control of Linux processes. You'll even get a whirlwind introduction to shell
pipelines, redirection, and text processing commands. By the end of this
tutorial, you'll have a solid grounding in basic Linux administration and will
be ready to begin learning more advanced Linux system administration skills in
the follow-on tutorial.

<p>
Welcome to "Basic administration," the second of four tutorials designed to
prepare you for the Linux Professional Institute's 101 exam. In this tutorial,
we'll show you how to use regular expressions to search files for text
patterns. Next, we'll introduce you to the Filesystem Hierarchy Standard (FSH),
and then show you how to locate files on your system. Then, we'll show you how
to take full control of Linux processes by running them in the background,
listing processes, detaching processes from the terminal, and more. Next, we'll
give you a whirlwind introduction to shell pipelines, redirection, and text
processing commands. Finally, we'll introduce you to Linux kernel modules.
</p>
<p>
This particular tutorial (Part 2) is ideal for those who have a good basic
knowledge of bash and want to receive a solid introduction to basic Linux
administration tasks. If you are new to Linux, we recommend that you complete
Part 1 of this tutorial series first before continuing. For some, much of this
material will be new, but more experienced Linux users may find this tutorial
to be a great way of "rounding out" their basic Linux administration skills.
</p>
<p>
For those who have taken the release 1 version of this tutorial for reasons
other than LPI exam preparation, you probably don't need to take this one.
However, if you do plan to take the exams, you should strongly consider reading
this revised tutorial.

<title>Regular Expressions</title>
<section>
<title>What is a regular expression?</title>
<body>
<p>
A regular expression (also called a "regex" or "regexp") is a special syntax
used to describe text patterns. On Linux systems, regular expressions are
commonly used to find patterns of text, as well as to perform
search-and-replace operations on text streams.
</p>
</body>
</section>
<section>
<title>Glob comparison</title>
<body>
<p>
As we take a look at regular expressions, you may find that regular expression
syntax looks similar to the filename "globbing" syntax that we looked at in
Part 1. However, don't let this fool you; their similarity is only skin deep.
Both regular expressions and filename globbing patterns, while they may look
similar, are fundamentally different beasts.
</p>
</body>
</section>
<section>
<title>The simple substring</title>
<body>
<p>
With that caution, let's take a look at the most basic of regular expressions,
the simple substring. To do this, we're going to use <c>grep</c>, a command
that scans the contents of a file for a particular regular expression. grep
prints every line that matches the regular expression, and ignores every line
that doesn't:
</p>
<pre caption="grep in action">
$ <i>grep bash /etc/passwd</i>
operator:x:11:0:operator:/root:/bin/bash
root:x:0:0::/root:/bin/bash
ftp:x:40:1::/home/ftp:/bin/bash
</pre>
<p>
Above, the first parameter to <c>grep</c> is a regex; the second is a filename.
<c>grep</c> read each line in /etc/passwd and applied the simple substring
regex bash to it, looking for a match. If a match was found, <c>grep</c>
printed out the entire line; otherwise, the line was ignored.
</p>
</body>
</section>
<section>
<title>Understanding the simple substring</title>
<body>
<p>
In general, if you are searching for a substring, you can just specify the text
verbatim without supplying any "special" characters. The only time you'd need
to do anything special would be if your substring contained a +, ., *, [, ], or
\, in which case these characters would need to be enclosed in quotes and
preceded by a backslash. Here are a few more examples of simple substring
regular expressions:
</p>
<ul>
<li>/tmp (scans for the literal string /tmp)</li>
<li>"\[box\]" (scans for the literal string [box])</li>
<li>"\*funny\*" (scans for the literal string *funny*)</li>
<li>"ld\.so" (scans for the literal string ld.so)</li>
</ul>
