How to execute system commands (linux/bsd) using Java (5 个回答)

我想制作一个在后台运行 bash 进程的 java Web 界面。那么，在java中如何运行像“ls -al”这样的linux命令或运行bash脚本。是否有任何包或java插件能够在JAVA中调用OS命令？

谢谢大家

正如我在这里所示:Compiling a C Source through javacode using gcc

您可以使用ProcessBuilder来做到这一点:

String directory = "/home/user";
String[] commands = {"ls", "-al"};

ProcessBuilder pb = new ProcessBuilder();
pb.directory(new File(directory));
pb.command(commands);

Process p = pb.start();

OuputStream out = p.getOutputStream(); // to send other commands/data
InputStream in = p.getInputStream(); // to read console response
// process the streams
