8. Using Linux Applications and Clients
This chapter describes how you can use Linux for common desktop computing tasks. You'll learn about popular desktop suites and applications. This chapter also introduces VMWare, a program that lets you run Microsoft Windows and Linux simultaneously, and WINE, a program that lets you run some Microsoft applictions under Linux.
The Debian Project is firmly committed to including only truly Open Source software in its main distribution. Not all the programs mentioned in this chapter and the next meet the Open Source definition. Part of the beauty of Linux, though, is the ease with which it can be enhanced. The Contributed and Non-free archives on the Debian site include a wealth of additional software, and some programs are available direct from third party providers.
8.1 Linux Desktop Applications
Not long ago, running Linux meant abandoning your easy-to-use WYSIWYG word processor or configuring your system for dual boot, so that you could boot Microsoft Windows or IBM OS/2 to access friendly and familiar desktop applications. At that time, Linux supported no robust, full-featured graphical desktop suites.
Today, Linux supports several desktop suites; several more are under development. Apparently, if rumors are to be believed, even Microsoft is considering adapting their Office desktop suite to run under Linux. Whether or not Linux users can expect to soon run Microsoft Office for Linux (or whatever name Microsoft might give this potential product), Linux users who prefer to avoid other operating systems can now do so without compromising their ability to produce first-rate documents, spreadsheets, and graphics.
This section describes the three most popular desktop applications for Linux:
In addition, this section briefly describes other desktop options:
The final section presents two entirely different approaches to desktop computing:
The VMware virtual platform, which lets you run Windows and Linux simultaneously on a single computer
WINE, which lets you run DOS and Windows programs under Linux
8.1.1 Applix Applixware
Applix distributes Applixware, a desktop suite available for a variety of platforms, including Microsoft Windows 9x, Microsoft Windows NT, and several varieties of UNIX, including Linux. Applixware is commercial software, but much less expensive than Microsoft Word. Currently, Applixware for Linux is priced at $99 (US); you can purchase it from the Applix web site, http://www.applix.com/. Print documentation and support programs are also available, at additional cost. If you prefer to try before buying, you can download a feature-disabled demo version; however, the download is quite large (over 38 MB) and therefore time-consuming (over 3 hours at 28.8 Kbps) unless you have a high-speed connection to the Internet.
Applixware includes eight main components:
Graphics, a drawing, charting, and graphics editing application
Data, an application for accessing data held in Oracle, Informix, Sybase, or CA-Ingres databases
Builder, an application development environment for decision support systems
8.1.1.1 Running Applixware
Once you've installed Applixware, you can run it by starting X and using a terminal window to issue the following commands:
DISPLAY=localhost:0 /opt/applix/applixIf you installed Applixware to a directory other than /opt/applix, you'll need to adapt the second command accordingly.
When Applixware starts up, it displays a window containing the Applixware main menu, shown in Figure 8.1. From the toolbar of the main menu, you can simply click to launch Words, Graphics and Presents, Spreadsheets, Mail, or Data. Alternatively, you can click on the asterisk icon, causing Applixware to display a menu, as shown in Figure 8.2.
Figure 8.1: The Applixware main menu
Figure 8.2: The Applixware application menu
Figure 8.3 shows the Words application. Words includes a spelling checker and supports document templates, tables, multimedia, and live links to Applixware and third-party documents. Moreover, it lets you import and export a variety of document formats, including Microsoft Word 2.0, 6.0, 7.0/95, and 97.
Figure 8.3: The Words application
Figure 8.4 shows the Presents application, which lets you create presentations in a way that resembles that provided by Microsoft PowerPoint. Presents provides features such as transitions and animation, HTML export, and templates. Its drawing tools let you draw lines, curves, and shapes, and perform other operations, such as rotations and fills. Presents can also import and export PowerPoint presentations and a variety of other document types.
Although a Linux application, such as Words or Presents, may be able to import a Microsoft Office document, the application may not be able to handle the full range of document and object types that can be embedded in an Office document. Some document and object types, for example, require access to a host application that runs only under Microsoft Windows.
Moreover, some Linux applications do not currently support all the styles and options of their Office counterparts. For example, if a document uses Microsoft's Visual Basic for Applications, the document will probably not function correctly under Linux.
If you plan on moving documents to and from Office, you may want to save your documents in a portable format (such as RTF), rather than a Microsoft proprietary format. This will significantly improve the chances that your document will work correctly both in Windows and Linux.
Figure 8.4: The Presents application
Figure 8.5 shows the Spreadsheets application, which provides functions similar to those of Microsoft Excel. Spreadsheets lets you create ordinary spreadsheets as well as 3D charts and sheets, and supports live links to objects created by Applixware and third-party applications, including Applix Data, which provides access to relational databases. Spreadsheets implements Applix's Extension Language Facility (ELF), which lets you add custom functions to the hundreds of built-in functions. Spreadsheets can import and export a variety of document types, including Lotus 1-2-3 (WKS, WK1, WK3, and WK4 files) and Microsoft Excel 3.0, 4.0, 5.0, 7.0/95, and 97.

8.1.2 StarOffice
Another popular Linux desktop suite is StarOffice, a product of Sun Microsystems. StarOffice is available free of charge from Sun's web site, http://www.sun.com/products/staroffice/. The download is about 70 MB, requiring over 6 hours at 28.8 Kbps. The office suite is also available on CD-ROM, for a cost of $9.95 plus shipping and handling.
StarOffice includes an extensive range of applications, including:
StarSchedule, a personal organizer that keeps track of events, tasks, contacts, and projects
StarImage, an image editor that provides many special effects
8.1.2.1 Installing StarOffice
To install StarOffice from a StarOffice CD-ROM, log in, mount the CD-ROM, change to the directory that is the mount point of the CD-ROM device, change to the Office50/english/prod_lnx subdirectory, and issue the setup command:
su - mount -t iso9660 /dev/cdrom /cdrom cd /cdrom/Office50/english/prod_lnx ./setupThe install program will guide you through the installation process.
If you have downloaded the personal edition, you have a tar file, rather than a CD-ROM diskette. The tar file has a name similar to so501_01.tar. Change to the directory in which you saved the tar file (for example, /download) and issue the following commands:
tar xvf so501_01.tar cd so501_inst ./setupIf you saved your tar file using a name other than so501_01.tar, you'll need to adapt the first and second commands accordingly. As when you install from CD-ROM diskette, the install program will guide you through the installation process.
Whether you're installing from CD-ROM diskette or a downloaded file, you should check the README file in the Office50 directory for additional information and instructions that will help you install and use StarOffice.
8.1.2.2 Running StarOffice
Once you have installed StarOffice, you can run it by starting X and using a terminal window to issue the following commands:
PATH=$PATH:/opt/Office50/bin sofficeIf you installed StarOffice into a directory other than /opt/Office50, you'll need to adapt the first command accordingly.
When StarOffice loads, it automatically launches the StarDesktop application, as shown in Figure 8.6. StarDesktop resembles Windows Explorer and the GNOME File Manager. It lets you point, click, drag, and drop to open and manage document files and folders.
Figure 8.6: StarDesktop
Figure 8.7 shows StarWriter, StarOffice's word processor. StarWriter provides PGP-encrypted email and other features not found in Microsoft Office 97. Like Applixware's Words, it imports and exports a variety of document types, including Microsoft Word 97.
Figure 8.7: StarWriter
Figure 8.8 shows StarImpress, the presentation graphics application included in StarOffice. Like Applixware's Presents, StarImpress imports and exports a variety of document types, including PowerPoint 97. StarImpress provides templates, animation and transitions, 3D effects, charts, and many other features.
Figure 8.8: StarImpress
Figure 8.9 shows StarDraw, StarOffice's drawing program. StarDraw provides a wide range of drawing tools and effects, and works with a variety of file types, including even Windows Metafile (WMF).
Figure 8.9: StarDraw
In addition to the bread-and-butter applications provided by Applixware, StarOffice provides several smaller, but quite useful, applications. For example, Figure 8.10 shows StarSchedule, which can help you keep track of the tasks on your to do list.
Figure 8.10: StarSchedule
8.1.3 Corel WordPerfect for Linux
Another popular desktop application is Corel's WordPerfect for Linux, available free of charge for personal use from Corel's web site, http://www.corel.com/. WordPerfect is more a word processor than a complete desktop suite; for example, no spreadsheet application accompanies it. However, WordPerfect does provide many functions and features, including:
A personal retail version (currently available for $69.95 US) adds features such as:
The downloadable version is about 24 MB in size, about a 2 hour download at 28.8 Kbps.
8.1.3.1 Installing WordPerfect for Linux
To install the downloaded version of WordPerfect for Linux, change to the directory that contains the downloaded file and issue the following command:
DISPLAY=localhost:0Then start X, open a terminal window, and issue the following commands:
cd /download tar zxvf wp.tgz ./RunmeIf your downloaded file has a name other than wp.tgz or if it resides in a directory other than /download, you'll need to adapt these commands accordingly.
The install program will guide you through the installation process.
To install the CD-ROM version of WordPerfect for Linux, follow the instructions that accompany the CD-ROM.
Some web sites, including the Corel web site, may provide WordPerfect for Linux as an uncompressed file. If the tar command fails with an error message indicating that the file is not in the gzip format, use the following command to unpack the file:
tar xvf wp.tgz8.1.3.2 Running WordPerfect for Linux
Once you've installed WordPerfect for Linux, you can run it by starting X and using a terminal window to issue the command:
/opt/corelwp8/wpbin/xwpFigure 8.11 shows WordPerfect for Linux in operation.

8.1.4 Other Desktop Applications
Table 8.1 describes some other desktop applications available for Linux. Notable among these is TeX, a freely available desktop publishing package of unsurpassed power. Because of its powerful and sophisticated handling of formulas and mathematical notation, TeX is a favorite among scientists and mathematicians.
