Section 11.4:A Larger Picture of the Filesystem
Look around a little in the /usr directory. From your current location in /etc/skel, type:
[newuser@localhost /skel]$ cd /usr
[newuser@localhost /usr]$ ls
If you forgot, cd /usr moves you to the /usr directory and ls lists the files in that directory.
In /usr, you will see a number of directories that hold some of your system's most important pro-
grams and files (see Figure 11–8, Typing ls in /usr ).
Figure 11–8 Typing ls in /usr
In /usr/share/man, you will find the system manual pages; other documentation that is not cov-
ered by man pages will be found in /usr/share/doc and in /usr/share/info.
In /usr/X11R6, you will find files related to the X Window System, including configuration and
documentation files.
In /usr/lib you will find files which are considered libraries for your system. Libraries contain
commonly used code that can be shared by many programs.
Red Hat Linux uses the RPM technology of software installation and upgrades. Using RPM, either
from the shell prompt or through Gnome-RPM, is a safe and convenient way to upgrade or install soft-
ware. For more information about using Gnome-RPM, see the Official Red Hat Linux Customization
Guide.
