 1   private void shell(String cmd)

 3           String[] cmds = { "/bin/sh", "-c", cmd };
 4           Process process;

 7           {
 8               process = Runtime.getRuntime().exec(cmds);

10              StreamGobbler errorGobbler = new StreamGobbler(process.getErrorStream(), "Error");
11              StreamGobbler outputGobbler = new StreamGobbler(process.getInputStream(), "Output");
12              errorGobbler.start();
13              outputGobbler.start();
14              try
15              {
16                  process.waitFor();
17              }
18              catch (InterruptedException e)
19              {
20                  e.printStackTrace();
21              }
22          }
23          catch (IOException e)
24          {
25              e.printStackTrace();
26          }
27      }

 

参数 cmd 为Linux命令。每次只能执行一条命令。

  1. Java Runtime.exec()注意事项
  • 永远要在调用waitFor()方法之前读取数据流
  • 永远要先从标准错误流中读取，然后再读取标准输出流

      2.最好的执行系统命令的方法就是写个bat文件或是shell脚本。
