Operation Manual

If HOWTOs are installed on your system /usr/share/doc also holds the

howto subdirectory in which to nd additional documentation on many tasks re-

lated to the setup and operation of Linux software.

/var

Whereas /usr holds static, read-only data, /var is for data which is written during

system operation and thus is variable data, such as log les or spooling data. For

an overview of the most important log les you can nd under /var/log/, refer

to Table “Log Files” (↑Start-Up).

/windows

Only available if you have both Microsoft Windows and Linux installed on your

system. Contains the Windows data available on the Windows partition of your

system. Whether you can edit the data in this directory depends on the le system

your Windows partition uses. If it is FAT32, you can open and edit the les in this

directory. For NTFS, openSUSE also includes write access support. However, the

driver for the NTFS-3g le system has limited functionality. Learn more in Sec-

tion 37.4, “Accessing Files on Different OS on the Same Computer” (page 614).

22.2 Writing Shell Scripts

Shell scripts are a convenient way of doing all sorts of tasks: collecting data, searching

for a word or phrase in a text and many other useful things. The following example

shows a small shell script that prints a text:

Example 22.1

A Shell Script Printing a Text

#!/bin/sh ❶

# Output the following line: ❷

echo "Hello World" ❸

❶

The rst line begins with the Shebang characters (#!) which is an indicator that

this le is a script. The script is executed with the specied interpreter after the
