This tool is written totally in BASH to install the latest stable version of the Vivaldi web browser from their repo.
There are two versions which include one for DEB based 64-bit hardware systems (Debian, Ubuntu, Mint, etc) and one for DEB and RPM based systems running on either 32-bit or 64-bit hardware. The second script will auto detect the package manager type, system bit, and correct repo URL.
Both scripts will download the latest stable version, install Vivaldi, then remove the installation file. The programs are designed to run on their own however can easily be added to another script or called by one.
