To install software on Linux systems, users will be using one of many installation-file formats. However, each Linux distribution only supports one or more types of installation files. For instance, RedHat-based systems use RPM files for installing new applications. A Debian-based system cannot read an RPM file. So, what if a RedHat user finds an application that they want to install, but the installation-file is a DEB file? Thankfully, there is a program called Alien that can convert installation-files.
