ProcessBuilder工具类及执行多条命令

            }
        }
    }

执行多条命令：

* List<String> commend = new ArrayList<>();
 * commend.add("/bin/sh");
 * commend.add("-c");
 * //   /bin/bash -c 7zzs x /usr/data/tmp/测试.zip -o/usr/data/tmp/one/ && convmv -f GBK -t utf8 --notest -r /usr/data/tmp/one/
 * commend.add("第1条命令 && 第2条命令 && 第3条命令 ..."); //这里可以实现执行多条linux命令
 * Process process = ProcessBuilder.exec(commend);
 * String message = ProcessBuilder.getOutput(process);
 * String error = ProcessBuilder.getError(process);
 * ProcessBuilder.destroy(process);
