shfmt is (mostly) a good idea, (even though it won't let me split the long android vlc command, should I reduce that line on a roundabout way?) but I don't like that it's lumped together with shellcheck. Even version bump has its own check!

[Derisis13]

I also suggest adding the -p argument to the shfmt check

Original idea of splitting long lines came from @medanisjbara please credit him whoever ends up merging this

On termux side, since spliting is good idea, what if it doesn't launch app, that's the only concern
