Using Sudosh with Golang
问题
我的程序的目的是执行一些任务，然后在最后以一个用户的身份进行 sudosh。
然而，当我用 Go 运行时，我得到了 sudosh: couldn't get your controlling terminal 的错误。
这是因为 sudosh 正在寻找一个控制终端，但找不到吗？在 Go 中是否可以实现这个功能？我正在将一个 Python 脚本转换为这个 Go 程序，在 Python 中它可以正常工作。
import (
"github.com/codeskyblue/go-sh"
"fmt"
"os"
)
c, _ := sh.Command("sudo", "sudosh", "bob").Output()
fmt.Println(c)
os.Exit(0)
修复方法
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
}
英文:
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
}

得分: 1
sudo2sh source显示它正在尝试调用ttyname，在go-sh.Command调用exec.Command(cmd, args...)的上下文中可能无法工作。
您可以通过直接调用ttyname进行测试，或者尝试实现一个TTYname()函数，就像这个线程中所示。
您还可以检查go-termutil的isatty函数来调试此问题（如此答案中所示）。
底线是：如果在exec.Command会话中ttyname失败，sudosh将始终返回该错误消息。
英文:
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.
