如何从JAVA运行linux命令？

Question

我想创建一个在后台运行bash进程的java web界面。那么，在java中如何运行linux命令，如＆＃34; ls -al＆＃34;或运行bash脚本。是否有任何能够在JAVA中调用OS命令的包或java插件？

全部谢谢

Answer 1

正如我在此处所示：Compiling a C Source through javacode using gcc

您可以使用ProcessBuilder来执行此操作：

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

您可以使用Runtime.exec()方法。
