prompter: How do I install apps on Linux?

assistant: How you install apps is determined by your Linux distribution and package manager. Here are some examples for common Linux distributions:

Debian- and Ubuntu-based distributions:
```sh
sudo apt install <package name>
```

Red Hat Enterprise Linux, CentOS, Fedora, and other RPM-based distributions:

Using yum:
```sh
sudo yum install <package name>
```

Using dnf (next-generation yum):
```sh
sudo dnf install <package name>
```

Packages that aren't available in your package manager must be manually downloaded and installed.

prompter: I am new to Linux and am not that good with computers. Where should I type these commands and what is a package manager? I think I am using Ubuntu as my Linux distribution.

assistant: In Ubuntu you need to enter these commands into your Terminal application. You can find the terminal by pressing the Super (Windows) key on your keyboard and then typing 'Terminal'. Alternatively you can press CTRL + ALT + T to immediately open the default Terminal application.

Once the terminal is opened, you can enter the commands previously mentioned to install new software.

Please feel free to ask me if you require any further assistance.

prompter: how can i know which linux i'm using ?

prompter: so if I'm building an installer script of my package for all Linux users, how can I run it without knowing which distribution it is?

assistant: This depends on the distribution you're using. Many beginner-friendly distros have "app stores", such as Ubuntu's Software Center or Pop!_OS's Pop!_Shop.

If you can't find anything like that, you might need to use a command-line package manager. Most common distributions are based on Debian and thus use `apt`, which does have a graphical version called Aptitude. Other possibilities include `rpm` for Fedora and `pacman` for Arch-based systems, as well as the cross-platform solutions `flatpak` and `snap`.

Rarely, you'll need to install apps from third-party websites instead of a centralized repository. If your downloaded file ends in `.deb` or `.rpm`, it's a package for Debian or Fedora respectively. If it ends in `.appimage`, it's a portable app that doesn't require installation; simply make it executable in the file properties window. If it has no extension at all, you can try that too, but it might need other files to be in the same folder as it.

prompter: how can I tell which distribute I have

prompter: how would i go about knowing which distribution i'm using ?

assistant: The process of installing apps on Linux depends on the specific Linux distribution you are using. Here are some common methods:

1 - Package Manager: Most Linux distributions have a package manager that allows you to easily install and manage software packages. For example, on Ubuntu and Debian-based systems, you can use apt-get or the Ubuntu Software Center.
Snap packages: Snap is a universal package format that works across many distributions. You can install snap packages using the snap command.
2 - Flatpak: Flatpak is another universal package format for Linux. You can install flatpak packages using the flatpak command.
RPM packages: On Red Hat-based systems, you can install RPM packages using the yum or dnf package managers.
Source code: If a software package is not available through a package manager, you can often download and compile the source code yourself.

Note: It's always recommended to use packages from official sources, as downloading packages from unofficial sources could potentially harm your system.
