相当于golang中python的utils.execute()

I am newbie to golang and am currently working with binaries in python with utils.execute(). I have to convert the code to golang, what's the equivalent to it in go?

图片转代码服务由CSDN问答提供 功能建议

我是golang的新手,目前正在使用utils.execute()在python中使用二进制文件。 我必须将代码转换为golang,在go中等效于什么?

    You can check golang exec.Command, as in os/exec/example_test.go

    func ExampleCommand() {
        cmd := exec.Command("tr", "a-z", "A-Z")
        cmd.Stdin = strings.NewReader("some input")
        var out bytes.Buffer
        cmd.Stdout = &out
        err := cmd.Run()
        if err != nil {
            log.Fatal(err)
        }
        fmt.Printf("in all caps: %q
    ", out.String())
    }
    

    First parameter is the command you want to execute, the rest are the parameters.

    func Command(name string, arg ...string) *Cmd
    

    In that same os/exec/example_test.go, you will find examples on how to read the output, start a command or even do a pipe.
