相当于golang中python的utils.execute（）

Question

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?

Answer 1

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.
