+
+<p><tt class="COMMAND">vi</tt>(1) is the standard Unix text editing program, and while
+mastering it is not as essential as it once was, is still a very rewarding goal. There
+are several versions (or clones) of <tt class="COMMAND">vi</tt> available, including <tt
+class="COMMAND">vi</tt>, <tt class="COMMAND">elvis</tt>, <tt class="COMMAND">vile</tt>,
+and <tt class="COMMAND">vim</tt>. One of these is available on just about any version of
+Unix, as well as on Linux. All of these versions include the same basic feature set and
+commands, so learning one clone should make it easy to learn another. With the variety of
+text editors included with Linux distributions and Unix variants these days, many people
+no longer use <tt class="COMMAND">vi</tt>. Still, it remains the most universal text
+editor across Unix and Unix work-alikes. Mastering <tt class="COMMAND">vi</tt> means you
+should never be sitting at a Unix machine and not be comfortable with at least one
+powerful text editor.</p>
+
+<p><tt class="COMMAND">vi</tt> includes a number of powerful features including syntax
+highlighting, code formatting, a powerful search-and-replace mechanism, macros, and more.
+These features make it especially attractive to programmers, web developers, and the
+like. System administrators will appreciate the automation and integration with the shell
+that is possible.</p>
+
+<p>On Slackware Linux, the default version of <tt class="COMMAND">vi</tt> available is
+<tt class="COMMAND">elvis</tt>. Other versions - including <tt class="COMMAND">vim</tt>
+and <tt class="COMMAND">gvim</tt> - are available if you've installed the proper
+packages. <tt class="COMMAND">gvim</tt> is an X Window version of <tt
+class="COMMAND">vim</tt> that includes toolbars, detachable menus, and dialog boxes.</p>
+
+<div class="SECT1">
+<h1 class="SECT1"><a id="VI-STARTING" name="VI-STARTING">16.1 Starting vi</a></h1>
+
+<p><tt class="COMMAND">vi</tt> can be started from the command line in a variety of ways.
+The simplest form is just:</p>
+
+<table border="0" bgcolor="#E0E0E0" width="100%">
+<tr>
+<td>
+<pre class="SCREEN">
+<samp class="PROMPT">%</samp> <kbd class="USERINPUT">vi</kbd>
+</pre>
+</td>
+</tr>
+</table>
+
+<div class="FIGURE"><a id="FIG-VI-VIM-SPLITEDIT" name="FIG-VI-VIM-SPLITEDIT"></a>
+<p><b>Figure 16-1. A vi session.</b></p>
+
+<p><img src="vi/vim-splitedit.png" /></p>
+</div>
+
+<p>This will start up <tt class="COMMAND">vi</tt> with an empty buffer. At this point,
+you'll see a mostly blank screen. It is now in &#8220;command mode&#8221;, waiting for
+you to do something. For a discussion of the various <tt class="COMMAND">vi</tt> modes,
+see the <a href="vi-modes.html">Section 16.2</a>. In order to quit out of <tt
+class="COMMAND">vi</tt>, type the following:</p>
+
+<table border="0" bgcolor="#E0E0E0" width="100%">
+<tr>
+<td>
+<pre class="SCREEN">
+<kbd class="USERINPUT">:q</kbd>
+</pre>
+</td>
+</tr>
+</table>
+
+<p>Assuming that there have been no changes to the file, this will cause <tt
+class="COMMAND">vi</tt> to quit. If there have been changes made, it will warn you that
+there have been changes and tell you how to disregard them. Disregarding changes usually
+means appending an exclamation point after the &#8220;<b class="KEYCAP">q</b>&#8221; like
+so:</p>
+
+<table border="0" bgcolor="#E0E0E0" width="100%">
+<tr>
+<td>
+<pre class="SCREEN">
+<kbd class="USERINPUT">:q!</kbd>
+</pre>
+</td>
+</tr>
+</table>
+
+<p>The exclamation point usually means to force some action. We'll discuss it and other
+key combinations in further details later.</p>
+
+<p>You can also start <tt class="COMMAND">vi</tt> with a pre-existing file. For example,
+the file <tt class="FILENAME">/etc/resolv.conf</tt> would be opened like so:</p>
+
+<table border="0" bgcolor="#E0E0E0" width="100%">
+<tr>
+<td>
+<pre class="SCREEN">
+<samp class="PROMPT">%</samp> <kbd class="USERINPUT">vi /etc/resolv.conf</kbd>
+</pre>
+</td>
+</tr>
+</table>
+
+<p>Finally, <tt class="COMMAND">vi</tt> can be started on a particular line of a file.
+This is especially useful for programmers when an error message includes the line their
+program bombed on. For example, you could start up <tt class="COMMAND">vi</tt> on line 47
+of <tt class="FILENAME">/usr/src/linux/init/main.c</tt> like so:</p>
+
+<table border="0" bgcolor="#E0E0E0" width="100%">
+<tr>
+<td>
+<pre class="SCREEN">
+<samp class="PROMPT">%</samp> <kbd
+class="USERINPUT">vi +47 /usr/src/linux/init/main.c</kbd>
+</pre>
+</td>
+</tr>
+</table>
+
+<p><tt class="COMMAND">vi</tt> will display the given file and will place the cursor at
+the specified line. In the case where you specify a line that is after the end of the
+file, <tt class="COMMAND">vi</tt> will place the cursor on the last line. This is
+especially helpful for programmers, as they can jump straight to the location in the file
+that an error occurred, without having to search for it.</p>
