Other Hello world Golang script

She-bangs are weird! The only issue is you can't use /usr/bin/env

TL;DR:

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

import "fmt"

func main() {
    fmt.Println("Hello world")
}

On FreeBSD, with go125 installed, the path should be /usr/local/go125/bin/go

Indeed, it works like a charm. I tried a bit different comment:

//usr/bin/env go run "$0" "$@"; exit; */
package main
import "fmt"
func main() { fmt.Println("hello from go")

- /bin/sh suspect
- /bin/tcsh suspect (I use this one)

Both run pretty much the same logic on ENOEXEC (ERR#8 in case you use truss(1))

Wow, that's really interesting! From now on, I'm doing C-scripting only

prog.c

/*usr/bin/cc "${0}" && ./a.out ${@}; exit;*/
#include <stdio.h>

int
main(int argc, char **argv)
{
    int i;
    
    for (i = 1; i < argc; i++)
        printf("argv[%d]: %s\n", i, argv[i]);
    return (0);
}

$ ./prog.c hello world
argv[1]: hello
argv[2]: world

LOL it works!
