# 1. 执行程序,程序会卡在这里?以下是run_script.php运行程序：
# $script_link = $found_app["Exec"];
# # 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);
# 2. 对于Qt应用程序，个人觉得这里还是堵塞
eval $filename > "tmp/"$outputfilename 2>&1
#Using a more unique string to detect if the script is completed
# 这行文字重定向到tmp下的输出文件尾
