Both the GNOME and KDE desktops include simple text editors that are excellent
for creating shell scripts.
The Kate editor is my favorite graphical editor for Linux. It is available in the openSUSE
KDE desktop under the Utilities menu area. Figure 8.3 shows an example of a Kate
session.
Kate allows you to cut and paste text using the mouse, as well as handle multiple versions
of a text file. Kate was designed for programmers. It incorporates easy editing features
with extra features such as highlighting programming elements within the text.

FIGURE 8.3 The Kate text editor.
When creating a shell script file, you must specify the shell you are using in the first line
of the file. The format for this is:
#!/bin/bash
In a normal shell script line, the pound sign (#) is used as a comment??”the line isn??™t
processed by the shell. However, the first line is a special case, and the pound sign
followed by the exclamation point tells the shell what shell to run the script under (yes,
you can be using a bash shell and run your script using another shell).
