Debian-based installer script

[badders]

Hi All,
I've knocked together a (quite hacky) installation script, based on another I saw on here a long while ago, but with a few extra bits to automate it a little more.

Tested on Ubuntu 16.04 so far.

Please let me know if you spot any bugs I might have missed.

Code: Select all

#!/bin/bash

function show_help {
echo
echo
echo "MakeMKV Installer/Updater"
echo "========================="
echo
echo
echo "Options:"
echo
echo "-h | --help                               Show this help screen"
echo
echo "-f | --force                              Force Reinstall"
echo
echo "-k | --key                                Show MakeMKV Trial Key and exit"
echo
echo "-v | --version                            Print current/latest version then exit"
echo
echo "-i <version> |--install <version>         Install Version specified by <version>"
echo
exit 1
}
