With Java, run multiple commands in the same cmd.exe window
提问by singe3
I'm developing a Java application that will be run on a Windows computer occasionally. At some point I need to run a Cygwin prompt and performs some commands in it.
我正在开发一个偶尔会在 Windows 计算机上运行的 Java 应用程序。在某些时候，我需要运行 Cygwin 提示符并在其中执行一些命令。
I've found a topic where the Runtime class is used: http://www.javaquery.com/2011/03/how-to-execute-multiple-command-in.html
我找到了一个使用 Runtime 类的主题：http: //www.javaquery.com/2011/03/how-to-execute-multiple-command-in.html
However it doesn't launch a real cmd.exewindow, it's only run in background and the output is just printed on the Eclipse console.
但是它不会启动一个真正的cmd.exe窗口，它只在后台运行并且输出只是打印在 Eclipse 控制台上。
I'm looking for a solution to run a real cmd.exewindow and I need to pass as many commands as I want to that windows shell. Is this possible?
我正在寻找一个解决方案来运行一个真正的cmd.exe窗口，我需要向那个 windows shell 传递尽可能多的命令。这可能吗？

This one works... using && operator you can add one or commands to be executed in same command prompt
这个有效...使用 && 运算符，您可以添加一个或多个要在同一命令提示符下执行的命令
try {
Process p = Runtime
.getRuntime()
.exec("cmd /c start cmd.exe /K \"dir && ping localhost && echo end\"");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Consider the solution in herealso

Not quite sure , but if i properly understand your problem , try : for windows at java conifguration panel, there should be un-ticked the show console button.
不太确定，但如果我正确理解您的问题，请尝试：对于 Java 配置面板上的 Windows，应该取消勾选显示控制台按钮。

If you do not need to show a console on the screen, that is easy. You have some simple steps to follow :
如果您不需要在屏幕上显示控制台，那很容易。您可以遵循一些简单的步骤：
- start a
Processvia `Process cmd = new ProcessBuilder("cmd.exe").start(); - send your commands to
cmd.getOutputStream() - read the result of the commands from
cmd.getInputStream()and/orcmd.getErrorStream() - when finished with it close
cmd.getOutputStream(), and if necessary kill the process bycmd.destroy()
- 启动一个
Process通过`过程CMD =新的ProcessBuilder（ “cmd.exe的”）开始（）; - 将您的命令发送到
cmd.getOutputStream() - 从
cmd.getInputStream()和/或读取命令的结果cmd.getErrorStream() - 完成后关闭
cmd.getOutputStream()，并在必要时通过cmd.destroy()
Optionnaly, you can have output and error stream to be merged :
Optionnaly，您可以合并输出和错误流：
Process cmd = new ProcessBuilder("cmd.exe").redirectErrorStream(true).start();
then you simply ignore cmd.getErrorStream()and only read from cmd.getInputStream()
那么你只需忽略cmd.getErrorStream()并只读取cmd.getInputStream()
