Using the Text Editors Linux distributions include a number of applications known as text editors that you can use to create text files or edit system configuration files. Text editors are similar to word processing programs, but generally have fewer features, work only with text files, and might or might not support spell checking or formatting. The text editors range in features and ease of use, but are found on nearly every Linux distribution. The number of editors installed on your system depends on what software packages you’ve installed on the system. NOTE Use the vimtutor command to quickly learn how to use vi’s keyboard commands.
The tutorial takes less than 30 minutes, and it teaches new users how to start or stop the editor, navigate files, insert and delete text, and perform search, replace, and insert operations. Working with emacs Richard M.
Stallman’s GNU emacs editor, like vi, is included with Ubuntu and nearly every other Linux distribution. Unlike other Unix and Linux text editors, emacs is much more than a simple text editor—it is an editing environment and can be used to compile and build programs, act as an electronic diary, appointment book and calendar, compose and send electronic mail, read Usenet news, and even play games.
The reason for this capability is that emacs contains a built-in language interpreter that uses the Elisp ( emacs LISP) programming language. Emacs is not installed in Ubuntu by default; instead you’ll need to install it using apt-get or synaptic. The package you need is simply emacs.
You can start an emacs editing session like thisFIRST: $ emacs file.txt. TIP If you start emacs when using X11, the editor launches in its own floating window. To force emacs to display inside a terminal window instead of its own window (which can be useful if the window is a login at a remote computer), use the -nw command-line option like this: emacs -nw file.txt. The emacs editor uses an extensive set of keystroke and named commands, but you can work with it by using a basic command subset. Many of these basic commands require you to hold down the Ctrl key, or to first press a meta key (generally mapped to the Alt key). The basic commands are listed in Table 4.2.
