FTP User Permissions

[rsanchezgar]

Hi, I have a CENTOS and need help for the next:

Is there any way to create a user permission in order to have a user to save on a directory a file but with no permission to delete anything. Thatīs because the user is uploading files via FTP but I need that the user donīt delete the file once the file is on the server..

Thanks for your support.

if the user can save in a directory, the user has write permissions there;
but any user with write permissions on a directory/file, can delete it also.
Your only hope I can see is to write a snoppy script, that changes permissions
once the user has finished writing.
