bout linux - flatpak on the command line
This baby looks up the desktop files of flatpak and makes some shell scripts in the current dir (be careful!).Again, excuse my php :) I just prefer it to python (sorry).
Run this thing in your home dir's bin and it'll make a shell script for every installed flatpak with the short command name.
So you can just go:
chrome
pianocheetah
...you get the idea :/
here
next: .deb install home
