检查进程是否为 Go 应用程序（Linux/Unix）

Question

我正在使用 ps（特别是 psutil python 库）在我的 linux 机器上查看运行个进程的列表。我想确定哪些进程是运行 Go 应用程序（也就是说，它们是运行 Go 代码）。

下面是用 Go 编写的进程的 ps 输出。有什么表明是运行 Go代码吗？

Answer 1

简短的回答是否定的。编译代码时没有留下任何有关 language/compiler 生成它的信息。您可以查找 go-program 的症状，例如对您的 GOPATH 或其子目录的引用，但仅此而已。

Answer 2

除了@evanmcdonnal 的回答之外，还有一个（非常非常）hacky 的解决方案：

strings /path/to/binary/from/ps/output | grep 'runtime.gogc'

输出：

<snip>
runtime.gogc                                                                                            runtime.gogc   
runtime.gogc   
<snip>

这当然依赖于二进制格式不改变或以其他方式被混淆，这不是一个长期的好假设。我还假设 runtime.gogc 存在于所有 Go 二进制文件中（可能不存在）。

请注意，从操作的角度来看，非常很少有这样的有用信息。
