Category:List of Linux Programmes
This is a list of Linux programmes. I use many of these programmes on a daily basis. However, I have not mastered all of these just yet. I will provide links to individual programmes for further information, tutorials, and examples.
Some of these programs are standard utilities that will be found on any Unix or Unix-like operating system; indeed a system without such basic components as ls or sh could scarcely be described as truly Unix-like. Others are more special-purpose and may not be installed by default. Finally, some items on this list are simply separate applications which happen to have been written for Unix.
