Unless you are on familiar ground, you usu in ally occupy a map to puddle around any thumping area. To get from mavin place to another, the best map is a road map (or street map). If you are staying in one general area and are looking for places of interest, you need a holidaymaker map. Because we are staying within the context of Linux and were looking for things of interest, what I am going to give you now is a tourist map of Linux directories.
In later chapters, well go into detail near many of the directories that we are going to encounter here. For now, I am going to briefly describe where they are and what their functions are. As we get into different sections of the book, it will be a lot easier to run short ab prohibited and know how files relate if we already confuse an misgiving of the basic directory structure.
One thing I would like to berth out is that (for the most part) the directories of most UNIX systems are laid out according to the functionality of the files and programs within the directory. One enhancement that Linux makes is allowing things to be in more than than one place. For example, files that the system uses may be in one place and those that normal users need may be in another place. Linux takes advantage of links to allow the incumbent files to be in both places. Well talk more roughly links as we move on.
One question stack often ask is why it is necessary to know what all the directories are for. Well, it isnt. It isnt necessary to know them all, just the more in-chief(postnominal) ones. While working in tech support, I have talked numerous times with administrators who were trying to clean up their systems a little. Because they had little experience with UNIX systems, they ended up removing things that they thought were unnecessary, precisely turned out to be vital for the operation of the system. If they knew more about where things were and what they were for, they wouldnt have made these mistakes.
As we go by these directories, keep in mind that your...If you want to get a full essay, order it on our website: Orderessay
