如何调试“退出状态1”在Golang中运行exec.Command时出错 [英] How to debug "exit status 1" error when running exec.Command in Golang

问题描述

当我运行下面的代码：

cmd := exec.Command("find", "/", "-maxdepth", "1", "-exec", "wc", "-c", "{}", "\\")
var out bytes.Buffer
cmd.Stdout = &out
err := cmd.Run()
if err != nil {
    fmt.Println(err)
    return
}
fmt.Println("Result: " + out.String())

退出状态1

exit status 1

如何获取更详细的信息？

推荐答案

解决方案是使用Command对象的 Stderr 属性。这可以这样做：

The solution is to use the Stderr property of the Command object. This can be done like this:

cmd := exec.Command("find", "/", "-maxdepth", "1", "-exec", "wc", "-c", "{}", "\\")
var out bytes.Buffer
var stderr bytes.Buffer
cmd.Stdout = &out
cmd.Stderr = &stderr
err := cmd.Run()
if err != nil {
    fmt.Println(fmt.Sprint(err) + ": " + stderr.String())
    return
}
fmt.Println("Result: " + out.String())

运行上面的代码，会清楚问题是什么：

Running the above code, would make it clear what the issue is:

退出状态1：find：-exec：no terminated;或+

exit status 1: find: -exec: no terminating ";" or "+"
