Installing a Graphical Package Manager
When installing new applications, there are a few steps that need
to be taken:
1. Find out whether the application is compatible with
the OS.
2. Install any other pieces of software that this new
application requires.
3. Download the application from the Internet.
4. Install the application to the correct folders.
In Linux, the package manager handles all of this for you. You
can also use it to uninstall applications that you do not want
anymore. Package managers connect to repositories – online
libraries of software. And since Linux is open-source, most of the
software in these repositories is also open-source (and free).
The package manager that is built-in to Raspbian is accessed
from the command line. However, you can also install one that
runs in the graphical desktop environment.
One such tool is Synaptic. To install it, use the command-line
package manager:
1. On the Application Launcher, click LXTerminal.
2. Type the following command and then press Enter:
sudo apt-get install synaptic
3. When the process is complete, type the following
command and then press Enter:
exit
Search the file for a word or phrase Press Ctrl + F.
Undo the last change that you
made
Press Ctrl + Z.
Quit Leafpad Press Ctrl + Q.
