The information provided in this book is provided "as is" with no implied warranties or guarantees. Well, all of these tools have their place, but a professional user needs professional tools. You have opted for Vim - a very good choice. Vim was created when system resources were limited.

These times have passed, but the result is a highly stable editor that runs on virtually any platform and has an exceptional command concept. It is certainly one of the best editors available for programmers. If you are adept with it, you can reach an incredible level of productivity.

Vim offers just about everything you could ever want from an editor. What remains can be handled with macros, plug-ins and command line utilities. Mastering an advanced editor is no small investment. However, after many years of experience, I can assure you that the effort bears interest richly.

And do not forget, learning how to wield its power well can be a lot of fun, along the way! The best that can happen is when an experienced user shows you the way and accompanies you as you learn. This book does exactly this. The learning curve is quite steep. After you have mastered the basics, you will learn step by step more advanced techniques.

In order to become a master yourself, you only need three things: practice, practice, practice. This book will guide you for weeks or months there. Now there is much to do, but you will have a very interesting time and gain much by it. Enjoy using Vim effectively. It's best to start immediately. Opening a File There are two methods to open a file.

Method 1: Open from command line as explained above. For easy understanding let us separate these into two categories — basic modes and advanced modes. Basic Vim Modes It is absolutely essential to understand these three basic modes to use the Vim editor effectively. Insert This mode is for inserting text. Command Line This mode is for executing ex commands at the bottom of the editor.

The following steps explain how you do this with the help of these three modes. Step 1: Normal mode. Open the new file in Normal mode. Go to Insert mode, and type Hello World! Go to command line mode and type :wq to save the file and exit the editor.

For example, you can select a column of text and delete in visual mode.

This is why those keys were chosen for navigation. Note: If you are not comfortable with j, k, h and l keys, you can still use arrow keys to move around. If you exit and start the Vim editor, the line number display will not be present anymore. Typically you should be modifying only the local vimrc file.

All hacks mentioned in this book are tested against the latest stable version.

Execute :version from the Vim editor to identify the version of your Vim editor. Help Description :help or :h Vim built in help documentation :helpgrep pattern Search help using pattern. Instead of retyping similar commands again and again, you can use the Bash command line features to manipulate previous commands and execute them quickly and efficiently.

Complete complex tasks in a single line by combining multiple Linux commands and one or more Bash builtins. When there is a possibility that you might perform a task again at some point, write a bash shell script instead of manually performing that task.

Even when you dont have to write a single line of shell script which is not practical for most developers and sysadmins , you still need to understand the fundamental structure of Bash programming language, as most of programs and startup scripts are written in Bash shell script, which you might end-up debugging for various reasons.
