# . 执行程序,程序会卡在这里?以下是run_script.php运行程序：

#   # strval(): 用于获取变量对应的字符串值

#   # rand(): 返回随机整数

#   $random_string = strval(rand());

#   $random_string .= strval(rand());

#   # addslashes(): 在指定的预定义字符前添加反斜杠

#   $script_command = "./execute_command.sh \"".addslashes($script_link). "\" ".$random_string.".txt ".$lock_list;

#   # 获取系统执行结果最后一行

#   # system()第二个参数：如果提供的return_var参数，则外部命令执行后的

#   # 返回状态将会被设置到此变量中

#   $last_line = system($script_command." > /dev/null 2>/dev/null & ", $retval);

# . 对于Qt应用程序，个人觉得这里还是堵塞
