Why not *.sh files?

Why is every command in the `README`? I understand that it's "better" if we want to select individual commands, but what if we want to select all commands? I propose moving groups of commands to individual script files, each with its own category name, and have a `main.sh` that executes all scripts. This way, users can easily choose individual cmds, groups, or all simultaneously. I'm willing to open a PR, but I don't have time nowadays
