大虾请进，如何用java调用linux操作系统下的命令行？

[freelarry]

比如说我想在java中实现 打一个tar包

请大虾指教

[doway]

Runtime.getRuntime().exec("dir -l");

谢谢楼上的，但在linux下呢？

import java.io.BufferedInputStream;
import java.io.IOException;

public class ExecLs {

static public void main(String[] args) {
String cmd = "ls"

try {
Process ps = Runtime.getRuntime().exec(cmds);
System.out.print(loadStream(ps.getInputStream()));
System.err.print(loadStream(ps.getErrorStream()));
} catch(IOException ioe) {
ioe.printStackTrace();
}
}

// read an input-stream into a String
static String loadStream(InputStream in) throws IOException {
int ptr = 0;
in = new BufferedInputStream(in);
StringBuffer buffer = new StringBuffer();
while( (ptr = in.read()) != -1 ) {
buffer.append((char)ptr);
}
return buffer.toString();
}

}
