Installing new software (Debian, Red Hat, Slackware)

[dos2unix]

rpm is usually for packages that are already downloaded to my drive.
yum has been depracated for quite a while, it still works, but may not in the next releases.
dnf is the standard way to download and install packages from internet repos.
