vi(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 vi available, including vi, elvis, vile, +and vim. 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 vi. Still, it remains the most universal text +editor across Unix and Unix work-alikes. Mastering vi means you +should never be sitting at a Unix machine and not be comfortable with at least one +powerful text editor.

+ +

vi 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.

+ +

On Slackware Linux, the default version of vi available is +elvis. Other versions - including vim +and gvim - are available if you've installed the proper +packages. gvim is an X Window version of vim that includes toolbars, detachable menus, and dialog boxes.

+ +
+

16.1 Starting vi

+ +

vi can be started from the command line in a variety of ways. +The simplest form is just:

+ + + + + +
+
+% vi
+
+
+ +
+

Figure 16-1. A vi session.

+ +

+
+ +

This will start up vi 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 vi modes, +see the Section 16.2. In order to quit out of vi, type the following:

+ + + + + +
+
+:q
+
+
+ +

Assuming that there have been no changes to the file, this will cause vi 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 “q” like +so:

+ + + + + +
+
+:q!
+
+
+ +

The exclamation point usually means to force some action. We'll discuss it and other +key combinations in further details later.

+ +

You can also start vi with a pre-existing file. For example, +the file /etc/resolv.conf would be opened like so:

+ + + + + +
+
+% vi /etc/resolv.conf
+
+
+ +

Finally, vi 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 vi on line 47 +of /usr/src/linux/init/main.c like so:

+ + + + + +
+
+% vi +47 /usr/src/linux/init/main.c
+
+
+ +

vi 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, vi 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.
