If I understand you, you are asking to leave files at user_a or _b and but any
subdirs under that then delete the files at that level and higher. That is:
> /share_folder/user_a
/share_folder/user_a/txt1
/share_folder/user_a/txt2
/share_folder/user_a/dir1/txt1
/share_folder/user_a/dir1/txt2
/share_folder/user_a/dir2/txt3
/share_folder/user_a/dir2/txt4
In this case only those files located at dir1 or dir2 would be eligible for
removing.
Another point is you state files/folders. What I have seen so far only handles
the files. You would ave to either keep a count of number of entries under a
directory and subtract out when you delete a file. It becomes even more convoluted
when you could have another subdirectory under a subdirectory.
Here is the basic script already done, but I attempted to handle level of the
delete using 'tr' and counting the number of separators in your base and then if the
total number ws greater than 2 then the file could be deleted if > 30 days and
separator count greater 2. So here is one way to give it a shot. I am running under
xp prof. Without the tests, I had 625 files to delete while with the test that the
number of slashes had to be greater than 2, then dropped to 423.
Note: Does not address empty subdirectories!!
