Files and folders that are in root directory
 

Hi

I want to know about the files and directories in under root

I suggest you read this first - it is a link to the very first (sticky) post in this forum:
http://www.linuxquestions.org/questi...d.php?t=356388
You asked an almost identical question yesterday (double posted...) and even got answers - why don't you specify more clearly what you want to know instead of asking the question again and again?
Also: the other posts you created here today are of a similar quality and might be regarded as double posts - do report them yourself to the moderators to be closed and re-think your question!
