Installing Linux apps: A few good tips
Sooner or later, we all end up installing new software on our computers. Whether it's a new version of Firefox, or a cool game, or a video editing package, there comes a time when you want to make your system do more than it can do now.
Under Linux, installing new applications isn't a particularly hard task, but installations do come in several different varieties, so it's worth understanding the differences and what you'll need to know to make them work.
Option 1: Use the built-in package manager
The easiest way to get new software onto a Linux system is to use the integrated package management system that is included with your distribution. You can use the package manager to download thousands of software packages that have been pre-built and tested for your specific version of Linux.
In Linux, software packages are usually equivalent to applications, although an application may in fact consist of several packages. For example, a graphics editor app may be made up of a package with the main program, a package with the documentation, and a package with the system libraries that the application needs to run.
