如何从java程序在终端运行命令? [英] how to run a command at terminal from java program?

问题描述

我需要通过 JAVA 程序在 Fedora 16 的终端上运行命令.我尝试使用

I need to run a command at terminal in Fedora 16 from a JAVA program. I tried using

Runtime.getRuntime().exec("xterm"); 

但这只是打开终端，我无法执行任何命令.

but this just opens the terminal, i am unable to execute any command.

我也试过这个:

OutputStream out = null;
Process proc = new ProcessBuilder("xterm").start();
out = proc.getOutputStream();  
out.write("any command".getBytes());  
out.flush(); 

但我仍然只能打开终端，但不能运行命令.关于如何做到这一点的任何想法?

but still i can only open the terminal, but can't run the command. Any ideas as to how to do it?

推荐答案

你需要像这样使用 bash 可执行文件来运行它:

You need to run it using bash executable like this:

Runtime.getRuntime().exec("/bin/bash -c your_command");

更新:正如 xav 所建议的，建议使用ProcessBuilder 代替:

Update: As suggested by xav, it is advisable to use ProcessBuilder instead:

String[] args = new String[] {"/bin/bash", "-c", "your_command", "with", "args"};
Process proc = new ProcessBuilder(args).start();
