问题 I want to look for the oldest directory (inside a directory), and delete it. I am using the following: rm -R $(ls -1t | tail -1) ls -1t | tail -1 does indeed gives me the oldest directory, the the problem is that it is not deleting the directory, and that it also list files.

问题 The rmdir() function fails if the folder contains any files.

问题 I have a share that is a "junk drawer" for end-users. They are able to create folders and subfolders as they see fit. I need to implement a script to delete files created more than 31 days old. I have that started with Powershell. I need to follow up the file deletion script by deleting subfolders that are now empty. Because of the nesting of subfolders, I need to avoid deleting a subfolder that is empty of files, but has a subfolder below it that contains a file. For example: FILE3a is 10

问题 I have an application with 2 directories (books and export). If we create a book or a page of a book in the application a directory is added with the id of the page (this is for uploading resources). If we delete a page, the page (and it's directory) is removed from the database and the filesystem. However this resulted in a session loss (even an application restart). I've looked up some thing on google and found the following link. It seems to be a problem in ASP.NET 2.0 (and 3.5). Does
