For an actually intentional, non-cursed version of this, see the nix-shell shebang [0]:
> #! /usr/bin/env nix-shell > #! nix-shell -i python3 -p python3Packages.pillow python3Packages.ansicolor > > # scale image by 50% > import sys, PIL.Image, ansicolor > path = sys.argv[1] > image = PIL.Image.open(path) > factor = 0.5 > image = image.resize((round(image.width * factor), round(image.height * factor))) > path = path + ".s50.jpg" > image.save(path) > print(ansicolor.green(f"done {path}"))
Just `chmod +x` and you have an executable with all dependencies you specify!
