Go/Golang Run embedded bash script or node/js,python,php,ruby etc

Since Go v1.16 there’s the embed package, a simple tool to embed files as filesystems of simple strings or []bytes.

While it has its downsides, I was recently met with a challenge. I’d like to run bash scripts I wrote because it’s more efficient to just run a bash script than breaking my fingers writing os/exec stuff.

Imagine the possibilities. You can now embed PHP, JS, all kinds of scripting languages in Go and execute those scripts without ever needing to write any of the embedded content to disk.

And while that’s nice, I do have a problem. How do you pass arguments like this?
Thanks to Jon Lundy this problem is solved.
