Relatively new to Go. Seems trivial, but I can't figure out how to detect the OS version. I know I can use runtime.GOOS and runtime.GOARCH to get the platform and architecture, but say I know I'm on linux but I want to find if I'm on RH6 vice RH7, etc. is what I'm trying to figure out.

相对较新。 似乎微不足道,但我不知道如何检测操作系统版本。 我知道我可以使用 runtime.GOOS runtime.GOARCH 来获取平台和体系结构,但是说我知道我在linux上,但是我想知道是否 我想弄清楚RH6上的m和RH7等。

    So there's this obscure Uname method in the syscall package that basically does it, at least on Linux. The struct it fills is a bit clunky and undocumented, but you can get the gist of it:

    import (
    // A utility to convert the values to proper strings.
    func int8ToStr(arr []int8) string {
        b := make([]byte, 0, len(arr))
        for _, v := range arr {
            if v == 0x00 {
            b = append(b, byte(v))
        return string(b)
    func main() {
        var uname syscall.Utsname
        if err := syscall.Uname(&uname); err == nil {
            // extract members:
            // type Utsname struct {
            //  Sysname    [65]int8
            //  Nodename   [65]int8
            //  Release    [65]int8
            //  Version    [65]int8
            //  Machine    [65]int8
            //  Domainname [65]int8
            // }

    BTW This doesn't work on the playground, probably because of the sandbox limitations, but works on Linux. Haven't tested other systems.
