@DarkWolf I use a bash GUI. It has options for Kodi, RetroPie, PIXEL desktop, MC File Manager, RP SetUp Script, System info, reboot & shutdown. Just pick the option and it launches. Any script could be launched from it, including the type proposed by the OP.
Another, option is for him to create the script and just set up a bash alias. So a special codeword or password could just be entered in the shell and the script would run.
So handy for people not familiar with the system. The Pi is basically the living room home entertainment system. In a computer not much bigger than a credit card. What a time to be alive!
