Written with a clear, straightforward writing style and packed with step-by-step projects for direct, hands-on learning, Guide to UNIX Using Linux, 4E is the perfect resource for learning UNIX and Linux from the ground up. Through the use of practical examples, end-of-chapter reviews, and interactive exercises, novice users are transformed into confident UNIX/Linux users who can employ utilities, master files, manage and query data, create scripts, access a network or the Internet, and navigate popular user interfaces and software. The updated 4th edition incorporates coverage of the latest versions of UNIX and Linux, including new versions of Red Hat, Fedora, SUSE, and Ubuntu Linux. A new chapter has also been added to cover basic networking utilities, and several other chapters have been expanded to include additional information on the KDE and GNOME desktops, as well as coverage of the popular OpenOffice.org office suite. With a strong focus on universal UNIX and Linux commands that are transferable to all versions of Linux, this book is a "must-have" for anyone seeking to develop their knowledge of these systems.
accommodate all of the software that you install. Also, if you plan to have multiple users access the system, you can create a /home partition, which is the home directory for all users’ directories. Having separate /usr and /home partitions makes many system administration tasks, such as backing up only software or only data, much easier. The /home partition is the storage space for all users’ work. If the root partition (/)—or any other partition—crashes, having a /home partition ensures that
the bottom of the screen displays information, including lineoriented commands and error messages. Searching and Replacing Suppose you want to change all occurrences of “insure” in the file you are editing to “ensure.” Instead of searching for “insure,” and then deleting it and inserting “ensure,” you can search and replace with one command. The commands you learned so far are screen-oriented. Commands that can perform more than one action (searching and replacing) are line-oriented commands and
in files accessible. ASCII can represent up to 256 characters (bit patterns). binary file — A file containing non-ASCII characters (such as machine instructions). bit — The abbreviation for binary digit; a number composed of one of two numbers, 0 and 1. UNIX/Linux store all data in the form of binary digits. Because the computer consists of electronic circuits in either an on or off state, binary digits are perfect for representing these states. bitmap — The rows and columns of dots or bit
UNIX/Linux distributions come with vi. d. It is a screen editor. 9. While working in the Emacs editor, you delete a section of text and then decide to undo your deletion. Which of the following commands should you use? a. Use the Ctrl+u command. b. Use the Alt+u command. c. Use the Ctrl+x,u command. d. You’re stuck retyping the deleted text, because Emacs does not enable you to undelete. 10. When you copy text in Emacs, you must mark the text you want to copy by using which of the following
Step 3 to close the editor.) 3. Type :q! and press Enter again to close the vi editor. In Projects 3-15 through 3-20, you practice using the Emacs editor. In these projects, you start Emacs from the command line (such as a terminal window) using your own account. If Emacs is not installed and you are using Fedora or Red Hat Enterprise Linux with the GNOME desktop, log in to root, click Applications, click Add/Remove Software, click List, check the boxes for the Emacs installation options, click
