Slackware 13.0 x86_64 is released as stable! Thanks to everyone who
helped make this release possible -- see the RELEASE_NOTES for the
credits. The ISOs are off to the replicator. This time it will be a
6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD.
We're taking pre-orders now at store.slackware.com. Please consider
picking up a copy to help support the project. Once again, thanks to
the entire Slackware community for all the help testing and fixing
things and offering suggestions during this development cycle.
As always, have fun and enjoy! -P.

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 “command mode”, 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 “<b class="KEYCAP">q</b>” 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> +</div> +</div> + +<div class="NAVFOOTER"> +<hr align="LEFT" width="100%" /> +<table summary="Footer navigation table" width="100%" border="0" cellpadding="0" +cellspacing="0"> +<tr> +<td width="33%" align="left" valign="top"><a href="archive-files-zip.html" +accesskey="P">Prev</a></td> +<td width="34%" align="center" valign="top"><a href="index.html" +accesskey="H">Home</a></td> +<td width="33%" align="right" valign="top"><a href="vi-modes.html" +accesskey="N">Next</a></td> +</tr> + +<tr> +<td width="33%" align="left" valign="top"><tt class="COMMAND">zip</tt></td> +<td width="34%" align="center" valign="top"> </td> +<td width="33%" align="right" valign="top">Modes</td> +</tr> +</table> +</div> +</body> +</html> + |
