Hmm. Generally speak, if the file already exists, then the ownership
and modes are unchanged. Agreed it depends on the shell.

Agreed. When modifying or replacing a file it behooves you to understand
how to interact with the program(s) accessing to that file. It differs
depending on the program. You cannot treat a mailbox like a syslog file
and you cannot treat a syslog file like a multilog file, etc.
