Alright being kind of new to a unix enviornment and learning how to work with a pure command line interface how would one unistall an application like asterisk from the command line. I have to admit, the years of dealing windows and dos prompts have kept me in a close ended microsoft enviornment and i am trying my hardest to grasp the concepts of linux so bear with me.
Anyways my question is rather simple. How would I unstall an app from the command line such as Asterisk as I already have it installed but having troubles upgrading it and want to just put a fresh install from scratch. Normally in Windows I'd just install and re-install. I can only assume I have that same functionality in linux. I currently am using CentOS.
