如何在D中进行系统调用并读取标准输出？ [英] How to make a system call and read the stdout, in D?

问题描述

我想尝试将 D 用于一些需要高性能的系统管理脚本（用于比较性能）使用python / perl等）。

I thought to try using D for some system administration scripts which require high performance (for comparing performance with python/perl etc).

到目前为止，在我看过的教程（dsource.org等）中找不到一个示例。

I can't find an example in the tutorials I looked through so far (dsource.org etc.) on how to make a system call (i.e. calling another software) and receiving it's output from stdout, though?

如果我错过了它，有人可以将我指向正确的文档/教程，或者提供它吗？

If I missed it, could someone point me to the right docs/tutorial, or provide with the answer right away?

推荐答案

好吧，那我当然找到了： http://www.digitalmars.com/d/2.0/phobos/std_process.html#shell （使用此处的探戈库： http://www.dsource.org/projects/tango/wiki/ TutExec ）。

Well, then I of course found it: http://www.digitalmars.com/d/2.0/phobos/std_process.html#shell (Version using the Tango library here: http://www.dsource.org/projects/tango/wiki/TutExec).

以前的版本s是与D 2.0兼容的版本（因此ubuntu附带了当前的dmd编译器）。

The former version is the one that works with D 2.0 (thereby the current dmd compiler that comes with ubuntu).

我现在使用dmd编译了这个小例子：

I got this tiny example to work now, compiled with dmd:

import std.stdio;
import std.process;

void main() {
  string output = shell("ls -l");
  write(output);
}
