Ruby Language Installation Linux—Installation using a package manager
Example
Probably the easiest choice, but beware, the version is not always the newest one. Just open up terminal and type (depending on your distribution)
in Debian or Ubuntu using apt
$> sudo apt install ruby
in CentOS, openSUSE or Fedora
$> sudo yum install ruby
You can use the -y option so you are not prompted to agree with the installation but in my opinion it is a good practice to always check what is the package manager trying to install.
