You were introduced to the UNIX file system and
directories in Chapter 1. Hard disks are divided
into file systems and directories. These exist to group information into containers that categorize them. By organizing
or grouping files into directories, applications and users can find
their files when they need them. We will cover the creation of
directories and naming conventions later in the course. Directories
are created in one of four ways:
- They are created by the operating
system during installation.
Several standard Solaris directories are created when an operating
system (OS) is first installed. In the UNIX environment, these
include usr, dev, etc, export, kernel and others as shown in Figure . They are used by the OS to store files critical to the
operation of the computer including the kernel itself.
- They can be created by applications
during installation.
When applications are installed such as StarOffice ™,
directories are created automatically to give the application
places to store installation files and for use by the
application and users to store data files.
- The System Administrator can create
them.
When creating user accounts on a workstation or server, the System
administrator (Sysadmin) can create a particular directory or set
of directories depending on user needs.
- User can create their own
directories.
Users themselves can create directories providing they have proper
permission. By default, users have permission to create
subdirectories and files under their home directory. We will cover
directory and file permissions later in the course.
