"For each Linux application, we have compiled a portal page
providing an overview of the software, a screenshot of the
application in action, a comprehensive list of its features, and
links to sites offering information and support on the software
such as forums, tutorials, and reviews.
"Unlike their Window counterparts, the vast majority of the
Linux applications listed below are available to download without
charge (a few of the Linux equivalents are commercial, or released
under a proprietory license). Popular Linux distributions
conveniently include many of the software applications listed below
(see our Linux Distribution Guide if you are unsure what is meant
by the term distribution, or if you would like more information on
what they offer)."
