Sample text

For example, use :w if you just want to write the changes while working on a file without quitting it, or use :q! to quit the file without writing changes. The latter option is a nice panic key if something has happened that you absolutely don’t want to store on your system. This is useful because Vi will sometimes work magic with the content of your file when you hit the wrong keys. Alternatively, you can recover by using the u command to undo the most recent changes you made to the file. Cut, Copy, and Paste You don’t need a graphical interface to use cut, copy, and paste features; Vi could do this back in the seventies.

Bash has some useful features to make working with these line commands as easy as possible. Some shells offer the option to complete a command automatically. Bash has this feature, but it does more than just complete commands. Bash can complete almost everything: not just commands, but also file names and shell variables. CHAPTER 2 ■ GETTING THE MOST OUT OF THE COMMAND LINE Using Automatic Command Completion Using this feature is as simple as pressing the Tab key. For example, the cat line command is used to display the contents of an ASCII text file.

The command can also be modified to show any number of lines on the bottom of a file; for example, tail -2 /etc/passwd will display the last two lines of the configuration file in which user names are stored. Also very useful for monitoring what happens on your system is the option to keep tail open on a given log file. For example, if you use tail -f /var/log/messages, the most generic log file on your system is opened, and, when a new line is written to the bottom of that file, you will see it immediately.
