I use the advanced package tool (apt) eveytime I want to install a new app or search for software in my default repositories. But, what is apt for people that don't know?
What is apt
apt is used in debian based distributions to handle the installation and removal of software. It automatically downloads the specified packages, resolves their dependencies and installs them. The fact that apt has been ported to Mac OS X for some of its own package management system tells us that it is a very important package manager tool.
The Ubuntu Linux system I use makes use of the advanced package manager tool. I find it very useful to use and it helps me to manage my software in a very efficient way. For example, If I want to search if a specific package exists in the default repositories I use the following command.
sudo apt-cache search package_name
It the package exists it can be installed with the following command.
sudo apt-get install package_name
What command is used to update the packages? The following command is used to resynchronize the package index files from their sources.
sudo apt-get update
You can easily remove a package with the following command.
sudo apt-get remove package_name
A you can see apt is not a single program, it is a collection of tools. The sudo apt-get install package-name command works when the internet connection is available, but what happens if suddenly lose connection to the internet?
Have you ever been in a situation when you wanted to restore the same packages in your fresh Ubuntu installation but the lack of internet made it not possible for you to do that? I have been in this kind of situation and did not know what to do at that time.
Then I rediscovered the APTonCD tool.
What is APTonCD tool
I told you about APTonCD, but what is it? How can this tool help us? According to the official webpage of the APTonCD it is a graphical tool that can be used to save your packages you've downloaded via APT-GET or APTITUDE in a CD or DVD.
In other words the APTonCD tool can create a removeable repository which we can use on other computers that are not connected to the internet.
Why do I like APTonCD
I like and use APTonCD for the following reasons.
1. It is very easy to use and has a very clean user interface. In just a few click I can clone my packages and create a removeable repository.
2. It helps me to all downloaded packages (via apt-get, aptitude and synaptic) to restore later.
3. Install software in machines that don't have an internet connection. You can also share the packages with your friends, neighbours or other linux users.
4. I can take my favourite packages with me wherever I go. All this is done a few clicks. Installing your favourite packages on anytime wherever you are without the need of an internet connection, isn't that amazing?
