Question

我有一个FTP服务器，我的操作员通过FTP页面手动更新它，我不确切知道他什么时候这样做。

我想编写一个脚本来确定修改了哪个文件夹，并返回创建或修改的新文件夹的路径。

我应该说他通常在某个路径中创建一个新文件夹或删除它们。

现在通过ftp_nlist我递归地读取所有文件和文件夹，然后检查数据库中的路径是否是新的，我保存它，或者从数据库中删除这一行。

请分享您的想法和代码以获得最佳评价。

您可以通过bash脚本find检查文件夹和文件的上次修改时间。以下是一些php示例：

exec('find . -mtime -1 -type d', $output);
// $output: list of folders modified within 24 hours
unset($output);

exec('find . -mtime -1 -type f', $output);
// $output: list of files modified within 24 hours
unset($output);

exec('find . -mtime +0 -type f', $output);
// $output: list of files modified greater than 24 hours
unset($output);

您应该检查这些选项-amin，-atime，-cmin，-ctime，-mmin和-mtime。

   -amin n
          File was last accessed n minutes ago.

   -atime n
          File was last accessed n*24 hours ago.  When find figures out
          how many 24-hour periods ago the file was last accessed, any
          fractional part is ignored, so to match -atime +1, a file has
          to have been accessed at least two days ago.

   -cmin n
          File's status was last changed n minutes ago.

   -ctime n
          File's status was last changed n*24 hours ago.  See the
          comments for -atime to understand how rounding affects the
          interpretation of file status change times.

   -mmin n
          File's data was last modified n minutes ago.

   -mtime n
          File's data was last modified n*24 hours ago.  See the
          comments for -atime to understand how rounding affects the
          interpretation of file modification times.
