Whenever I download a tar file and try to unpack it I can never get it to work. The README files tell me to type 'make install' but whenever I do this I get something that says 'nothing to do with install.' What does this mean, and is there any other way to get the program installed?
My second question is this, how do completely unistall something? Like in Windows, there is the Add/Remove section. Is there anything like that or any command that does that?
Third question: in Linux there are so many files and directories that I dont know what they are or what there purpose is. Is there any way to figure out what each directories and files are important and what they do?
