# People who have learning disabilities that affect hand-eye coordination may also find it easier to perform certain tasks by keyboard. In fact, some screen objects are so small that people who do not have hand-eye coordination problems find it difficult to target and click on them. Mouseless techniques can be a boon to these people.
# When users develop temporary disabilities or are injured — for example, a broken arm, dislocated shoulder, or tennis elbow — the ability to use the mouse may be compromised, and a few keyboard techniques can be beneficial.

Hi Saurabh

Linux installation is quite simple.

Step 1: Download & save
Download the packages you want to install and save them on your computer.
Go to the folder where you saved the software package to.

Step 2: Open Properties dialog
Click on the package with your right mouse button.
Then click on the Properties menu item.

Step 3: Enable permissions
Go to the Permissions tab.
Check the Execute, Exec or Is Executable checkbox. If there are more than one Execute/Exec checkboxes, check the top-most one.

Click Close or OK, depending on the dialog.

Step 4: Uninstall previous and open
If you already have the software installed from your distributions packages or from the source, remove it first. Then open the package file.

If you are asked whether you want to display or run the package, click Run.

The installation will now begin. Follow further intructions that are displayed on the screen, if any.

Thanks n regards

NOTE: ROC was compiled with a maximum length of truth set to 100000. This value can be increased upon request.
* Version 2.5.1 was compiled with PGI 6.2 compilers, and it is installed in /usr/local/R-2.5.1/bin/, a directory that is not on users default path. To use this version, start it with the full path, that is, type /usr/local/R-2.5.1/bin/R
* Add-on packages for 2.5.1 are installed in /usr/local/R-2.5.1/lib64/R/library/ (please check this directory to see which packages are installed). Note that the Bioconductor package installed with version 2.5.1 does not have the restriction in ROC that was implemented in the installation with version 2.4.0.
* Both versions were compiled with PGI compilers, with Blas and Lapack support.

For the benifit of people new to Linux, I have written a generic explaination of howto install software in Linux. Note that some software may have specific installation proceedures, this HOWTO is not a substitute for reading the offical installation documentation

This HOWTO covers the following topics:

* Compiling and Installing software from source
* Installing RPM's using the Redhat Package Manager
* Installing using Debian's apt-get
* Installing mandrake things
* Installing with fedora / yum
* Installing slackware packages
* Installing software using Gentoo EMerge
* Installing binary files (.BIN/.SH)


If you have just installed GNU/Linux and would like to know how to install software on your new OS, I would recommend you read the "Compiling and installing software from source" section, as well as the section specifically for your GNU/Linux Distribution. Do not worry if you dont understand or remember everything written here straight away, book mark this page and use it as a reference page later on.

You can install software on linux through rpm and source code ( tar ball or zip).

Using RPM:
The program to work with RPM packages is appropriately named rpm. rpm runs in several different modes, but the most common tasks are install, upgrade, query, verify, and erase.

rpm -i (install)

When you install a package for the first time, you will use the -i or install mode. Simply point the rpm to a binary package and execute it. The rpm will be installed on your system. Installation normally takes seconds. Often when installing a package, I will add the -v (verbose) switch to provide more information about the process, and the -h (hash bar) switch to provide progress updates via hash (#) marks printed on the console as the package is installed. Here's an example of installing a package:

Listing 1. Installing MyPackage

$ rpm -ivh MyPackage-1.0.0.i386.rpm
Prep aring ... ############################## ##### ######## [100%]
1:MyPackage ############################## ##### ######## [100%]

That's it! MyPackage is now installed and ready to use.

rpm -U (upgrade)

That's it! MyPackage is now installed and ready to use.

rpm -U (upgrade)

Once a package has been installed, any attempt to install a package with the same name will result in a message that the package is already installed. If you want to update a package to a later version, use the -U switch to upgrade. Upgrade has another affect. When upgrade is run on multiple package names, it will try to put the packages in order of dependencies. In other words, required packages will be installed first. The upgrade switch can be used whether or not a package is already installed, so many people use it for installs as well as upgrades instead of using the -i switch. Here is an example of using the upgrade switch to load several rpm packages:

Listing 2. Interactive upgrade

$ rpm -Uvh My*.rpm
Preparing... ############################## ##### ######## [100%]
1:bMyPackageDep ############################## ##### ######## [ 50%]
1:aMyPackageNew ############################## ##### ######## [100%]

In the case above, bMyPackageDep was a prerequisite for aMyPackageNew, so even though the file names sorted in reverse order, rpm ordered them correctly.

Source code:

Since Linux is an open source operating system, it comes with all of the development tools required to compile software. While most of the packages that you work with will be provided as binary RPMs, you are not limited to only those packages. If you wish, you can download the raw source code and custom-compile it for your system.

You should be cautious about compiling from source on a production system as it may cause problems or void your support for commercial software which you are using on the system, such as IBM DB2. However, being familiar with compiling from source will allow you to apply patches to software and work with packages ported from other environments. Once you have compiled the code successfully, it is even possible to create your own RPM!

Ex: Installation of corewars-

The first step to compiling from source is to download the source code package from the Web site:
http://prdownloads.sour cefor ge.net/corewars/corewars-0.9.1 3.tar .gz?download

Once the code is downloaded, I expand the package.
tar -xvzf corewars-0.9.13.tar.gz

The configure script runs a series of tests on the system to determine the best way to compile the package for your distribution and architecture. It then createx a custom Makefile for your system. If there are problems with compiling on your system, configure tells you. configure will usually let you customize the features to be included in the compile, or let you provide parameters about locations of libraries or other needed files so that the package can be compiled successfully. Here we execute configure with no additional parameters:
