Question

I am running a command through the os/exec package that is called like this:

out, err := Exec("ffprobe -i '/media/Name of File.mp3' -show_entries format=duration -v quiet -of csv=p=0", true, true)

The function I have written to execute command line calls is:

func Exec(command string, showOutput bool, returnOutput bool) (string, error) {
    log.Println("Running command: " + command)

    lastQuote := rune(0)
    f := func(c rune) bool {
        switch {
        case c == lastQuote:
            lastQuote = rune(0)
            return false
        case lastQuote != rune(0):
            return false
        case unicode.In(c, unicode.Quotation_Mark):
            lastQuote = c
            return false
        default:
            return unicode.IsSpace(c)
        }
    }

    parts := strings.FieldsFunc(command, f)
    //parts = ["ffprobe", "-i", "'/media/Name of File.mp3'", "-show_entries", "format=duration", "-v", "quiet", "-of", "csv=p=0"]
    if returnOutput {
        data, err := exec.Command(parts[0], parts[1:]...).Output()
        if err != nil {
            return "", err
        }
        return string(data), nil
    } else {
        cmd := exec.Command(parts[0], parts[1:]...)
        if showOutput {
            cmd.Stderr = os.Stderr
            cmd.Stdout = os.Stdout
        }
        err := cmd.Run()
        if err != nil {
            return "", err
        }
    }

    return "", nil
}

The strings.Fields command splits the command on spaces and that is used as the string array to pass to the exec.Command function. The problem is that it is splitting the filename into different parts because of the space when that filepath needs to stay together. Even if I format the string array correctly so the filepath is in one part, the exec.Command still fails because there is a space. I need to be able to execute this script to honor the filepath as one argument with spaces.

Well, I figured it out.

var parts []string
preParts := strings.FieldsFunc(command, f)
for i := range preParts {
    part := preParts[i]
    parts = append(parts, strings.Replace(part, "'", "", -1))
}

I needed to remove the single quotes from the arg passed into the exec.Command function.
