Installing Applications in Linux has Never Been Easier!
Adept Manager is a program that comes installed with Kubuntu Linux that allows you to manage installing and removing applications on your Linux system.
To use Adept Manager open the program from your “K Menu” under “System”. Once you have the program open you can use the “Search” utility at the top of Adept Manager to find the program you are looking for.
For our example let’s install Firefox. Type “Firefox” into the “Search” field and Adept Manager will return several search results that have Firefox in the name or description.
Scroll down the list and look for the current version of Firefox. (At the time of this writing the two current versions of Firefox are 2.0 and 3.0) From the list let’s select “firefox-2″. We can tell that we are selecting the correct package by checking the package “Description” in the right side column.
Once you click on the package name a menu will open up. In the menu click the “Request Install” button. Now click the “Apply Changes” button at the top of Adept Manager.
Adept Manager will now install the selected software onto your system. You will see a prompt that displays the download status as Adept Manager downloads the needed files for installation. Once the files have been downloaded, Adept Manager will install the new software onto your system.
When Adept Manager has finished installing the new software you can locate the application through your K-Menu under the appropriate menu category. In this case, Firefox should be located under the “Internet” menu.
You have now successfully installed a new program in Linux. You can use Adept Manager to install a wide variety of programs for Linux if you are using Kubuntu.

There are over 130 Linux distributions (versions) and they can be administered (managed) by Linux Graphical User Interface (GUI) utilities – or by using Linux commands.
Linux GUI utilities give you a “point-and-click” interface for doing Linux administration tasks, like working with the Linux file system (to make directories and copy files), and to create Linux users. However, they are slow and awkward to use – and even worse, they are different from one Linux distribution to another!
On the flip side, Linux commands are virtually identical from one Linux distribution to another. So, when you learn a Linux command in one Linux distro, that same command will work in all 130+ Linux distros.
However, new Linux users often have difficulty learning how to use Linux commands to administer the Linux OS (operating system). This is because most Linux training materials are poorly written by Linux techies that don’t know how to write in plain English for people new to Linux.
Linux Tips: When you get Linux training, don’t spend time learning Linux GUI utilities – learn how to use Linux commands, even though they are a bit harder to learn than GUI utilities.
Linux Command Names
Linux command names are often an abbreviation of what the command does. For example, the rm command stands for remove.
Linux command names and command options are “case sensitive”. Lower case letters need to be typed in lower case and vice versa. You must type in a Linux command and the options of the command, exactly as shown.
Linux Tips: Be sure to put a space between the Linux command name, its options, and what the Linux command is being run “on”, such as the name of a file.
Linux Command Name Examples
Here are some Linux command examples. The task is described and then the Linux command name is shown.
make (create) a directory – the Linux command is md
create new Linux users – the useradd command is used for this
search the Linux file system for information – the Linux command is grep
see the “type” of a Linux file – the file command displays this information
see the names of new Linux users, currently working on the system – the Linux command is users
find Linux directories and files in the Linux file system – the command for this is called find
Linux video tutorials are an easy and fast way to get Linux training and actually “see” how to use Linux commands.
When you watch a Linux video tutorial, you get to see, hear and do! You see and hear how to run a Linux command and you can even pause the presentation so you can run the Linux command yourself!

Regular Ubuntu Linux Users and the (Lack of Use of the) root User
When you install Ubuntu Linux, you create a user, which is the “first” user and you can also create more users if you need to. When you create the “first” user, you assign this user a password – and this one is very important!
It is required to log in to the desktop (at the Linux GUI login prompt) as the “regular” (non-root) user – and this password is also required to be able to do the equivalent of logging in as the root user – when you’re working at the Linux prompt a terminal emulation window on the desktop.
By default, the root use is not “enabled” (not available) in Ubuntu and so you can’t log in as this user – which is an innovative thing – as it stops anyone from logging in to the desktop as this user – which should never be done!
Example of Running the Linux sudo Command – To Start Working as the root User

The /usr/share/doc Directory Path
The Linux doc (for documentation) directory is the parent directory for a few hundred subdirectories that contain information regarding software components. All of the subdirectories begin with the name of a software package and may end in “-x.x.x”, where the “x”s are numbers that show the current version number of the software.
For example, there may be a subdirectory below doc named bash-x.xx. The x.xx in the directory name, such as 2.05, shows the current version of the bash (Bourne Again Shell) installed on your system.
Linux Commands Training Tips: The Linux System Administration commands, concepts and tasks covered here apply to ALL other Linux distributions, including: Red Hat, Ubuntu, Kubuntu, Edubuntu, Slackware, Debian, SUSE, openSUSE – and Fedora.
Each of the subdirectories below doc, such as bash-x.xx contain help text files regarding the software components installed on your system.
A huge amount of useful information is included in these directories in files with names like: README, FAQ, INTRO and NEWS. If you are having difficulty with a software component, or even if you just want to know more about it, this is a good place to look for help and information.
