Chapter 2 unix linux

You may also want to read this article on the How-To Geek website, that has slightly different recommendations. A file that is stored in blocks that are physically next to each other can be accessed and manipulated faster than a file that is stored in discontiguous blocks.

The text also recommends a home partition to hold the personal files for each user in their own directories. The text discusses the first three folders in that image on page 64, and the discussion continues with several others through page The text agrees that UNIX and Linux like to see everything they encounter as a file, including hardware components.

You will not have to partition your virtual machine in our lab, but if you install Linux on an actual hard drive, you will need to know some of the material on pages 60 through The path to any file consists of a list of the directories that you pass through to find that file.

It need not be just the space needed to store the initial file. InMicrosoft eventually released Windows 3. Only the owner, a system administrator, a superuser, or a semi-talented hacker can do so. You want to change to a directory that is also a child of folder1 your sibling directory?

This information about changing the prompt is not used on a daily basis by anyone, so you should be aware that it exists and be able to look up the codes that might be used to change the system prompt as desired.

This chapter begins by telling us that a file is the basic structure for data storage. For the moment, note that the listing shows a d in the first column for items that are directories, and a dash for items that are files. Consider some other examples: The command to copy a file takes two arguments: When making partitions on a disk with UNIX or Linux, they are numbered and the first one is numbered 1.

Chapter 1: What is Linux

Each author, each distribution, and each friend who knows something about computers will have a different recommendation about the size of your swap partition. A user on the system must fall into one of three categories with respect to any particular file: Why does it matter that the extent is contiguous blocks of storage space?

The article linked above does a good job of explaining that UNIX and Linux think every partition is part of the same file system tree. Before you can add a file system to a hard drive, you have to create a partition on that drive to hold the file system.

Assume it is called child2. An inode is a data structure that holds information about and points to a file or a directory. I have also heard it called present working directory. Sometimes the short name is not an acronym.

To avoid confusion in naming partitions, use of automatic naming is recommended.

The author of that article points out that the beginning of UNIX and Linux file systems is always called the root, and is represented by the slash, also called forward slash character: That means they can read the file but not write to it or execute it. In fact, it is the basic structure for data and device use, as well.

Inthe only thing that the FSF were missing to make it a fully fledged operating system was The Kernel.

The text reminds us that folders are also called directories, which you will need to know when creating, removing, or otherwise managing them from a UNIX or Linux command line.Start studying Linux Chapter 2.
