Bash Functions

There are two important functions of the shell that can make your work a lot eas-
ier:

The history function — To repeat a command that has been entered before,
press

↑

until the previous command appears at the prompt. Move forward

through the list of previously entered commands by pressing

↓

. To edit the

command line, just move the cursor to the desired position using the arrow
keys and start typing. Use

Ctrl

to search in the history.

The expansion function — Expand a file name to its full length after typ-
ing its first letters until it can be uniquely identified. To do so, type the first
letters then hit

Tab

. If there are several file names starting with the same

letters, obtain a list of them by hitting

Tab

twice.

First Example: Managing Files

Now that you know what a command looks like, which directories exist in SUSE
LINUX, and how to speed up things when using Bash, put this knowledge into
practice with a small exercise.

1. Open a console from the KDE desktop by clicking the shell icon.

2. Enter the

command to see the contents of your home directory.

3. Use the command

mkdir

(which stands for make directory) to create a new

subdirectory called

test

by entering

mkdir test

4. Now launch the KEdit editor by pressing

Alt

and entering

kedit

in the

input field. Type a few letters in the editor then save the file as

Testfile

in your home directory. Linux distinguishes between uppercase and lower-
case. For this example, use an uppercase T.

5. View the contents of your home directory again. Instead of typing

again,

just press

↑

twice and the

command should reappear at the prompt. To

execute the command, hit

Enter

. The newly created directory

test

should

appear in blue letters and

Testfile

in black. This is how directories and

files can be distinguished in a console.
