在Golang中使用Sudosh

Question

my programs purpose is to do some tasks and then sudosh as a user all the way at the end.

However when running this with Go I get the sudosh: couldn't get your controlling terminal.

Is this because sudosh is looking for a controlling terminal and can't find it? Is this possible to do with Go? I am converting a Python script over to this Go program and it worked fine in Python.

import (
    "github.com/codeskyblue/go-sh"
    "fmt"
    "os"
)
c, _ := sh.Command("sudo", "sudosh", "bob").Output()
fmt.Println(c)
os.Exit(0)

sudosh: couldn't get your controlling terminal.

The Fix

import "os/exec"

func sudosh(name string) {
    c := exec.Command("/bin/sh", "-c", "sudo /path/to/sudosh " + name)
    c.Stdin = os.Stdin
    c.Stderr = os.Stderr
    c.Stdout = os.Stdout
    o := c.Run()
    o=o
}

Answer 1

sudo2sh source shows that it is trying to call ttyname, which might not work in the context of a go-sh.Command calling exec.Command(cmd, args...).

You can test by calling ttyname directly, or by trying and implement a TTYname() function as in this thread.
You can also check the isatty function of go-termutil to debug the issue (as in this answer).

The bottom line is: if ttyname fails in a exec.Command session, sudosh will always return that error message.
