Run Go program as script

script.go

//usr/bin/env go run $0 "$@"; exit
package main

import (
	"fmt"
	"os"
)

func main() {
	fmt.Println("Hello world!")
	cwd, _ := os.Getwd()
	fmt.Println("cwd:", cwd)
	fmt.Println("args:", os.Args[1:])
}

Unfortunately, this does not work properly. The exit code is always 1 or 0.

@msoap There is no way to get the correct error code from go run, unfortunately. See here: https://stackoverflow.com/questions/55731760/go-os-exit2-show-a-bash-value-of-1

I tested (very briefly) on macos with os.Exit(1) and os.Exit(7). What I see in this env is that the exit code is propagated, and can be captured with $? in the calling shell.
