Also i facing the below problem as well.

In my directory i am having many files and subdirectories. my directory is like below
drwxrwxr-x 5 root canusr 8192 Dec 5 12:50 tran

others dont have write permision

in side my directory the files i am having are
$cd tran
drwxr-xr-x 2 v1ftp cnur 8192 May 1 2007 v1ftp
drwxrwxrwx 3 v1ftp cnur 24576 Dec 24 06:00 v1
drwxrwxrwx 2 ham cnur 8192 Nov 6 09:28 itm
-rwxrwxrwx 1 scott cnur 1006258 Sep 19 15:33 7041012_cpy
-rwxrwxrwx 1 scott cnur 72928579 May 1 2007 uswst.gz

My question is :

When i use find and delete to delete the files that are 30 days old why the files 7041012_cpy and uswst.gz are not getting deleted .

Also the same find and delete command is deleting the file that 30 days old inside the dir v1

My Assumptions

Is that my directory is not having write permision the files in the dir is not getting deleted.


if so the how come the same command working and deleting the file inside the sub_directory.

Thanks,
Arun

All,

I have found some thing please correct me if i am wrong

1. If a file Doesnt have write permision we cannot delete the file
2. If a directory doesnt have write permision , We cannot delet eany files in sidethe directory.
3. If a directory doesnt have wrote permsion and its subdiretory has write permision we can delete the files inside the sub directory.

I am confused about this 3 rd point Even though the parent directory doesnt have write permision how unix allows the delete operation perform in it sub directory.

Thanks,
Arun
