Subject: Re: Any way to allow clobbering empty files when noclobber is set?
To: "zsh-workers@zsh.org" <zsh-workers@zsh.org>
Cc: Martin Tournoij <martin@arp242.net>
Content-Type: text/plain; charset="UTF-8"

The regular noclobber can use O_CREAT | O_EXCL to avoid races. How
would any of the proposed modifications work? That is, how to
implement unlink-if-empty without ever unlinking non-empty files? Or
how to implement clobber-if-empty without ever clobbering non-empty
files?
